DESCRIPTIONS OF NEW GENERA, SPECIES AND SUB-SPECIES OF BIRDS FROM PANAMA, COLOMBIA ANDECUADOR * By E. W. NELSONThe first of January, 191 2, E. A. Goldman, of the Biological Sur-vey, Department of Agriculture, was again detailed on the Smith-sonian Biological Survey of the Canal Zone. Tie returned to Pan-ama in January and remained there until the last of June passingmost of this period in collecting birds and mammals on the slopesof Mount Pirri on the Pacific side of eastern Panama, near theColombian border. Mount Pirri is the highest point (with an alti-tude of over 5,200 feet) of a rather narrow and isolated mountainridge lying southeast of San Miguel Bay and on the southwest sideof the Tuyra Valley. The extreme headwaters of the Tuyra Riverrise on its slopes. The ridge is connected southerly with the moun-tain divide between the valleys of the Tuyra in Panama and of theTruando River in Colombia. Mount Pirri is heavily forested andalthough on the southern, or Pacific, side of Panama it receives thebenefit of moist air currents from the Carribean so its summit isshrouded in fog most of the year while it has an extremely heavyrainfall.Previous to Goldman's work no zoological collector appears tohave visited this interesting mountain. Work was done from itsbasal lowlands to the summit and many birds and mammals not be-fore known from Panama were taken, a number of which are newto science. Many species from the South American fauna appearto here reach their northern limit and are unknown in the CanalZone or its adjacent mountains, only about 150 miles away in adirect line by land. In the present paper three apparently new-genera and twenty-four new species and subspecies of birds are de-scribed from the slopes of Mount Pirri and its bordering lowlands.In addition two new birds from Colombia and Ecuador and onefrom western Panama are included. 'Idle new mammals have beendescribed by Goldman," and later a faunal paper will probably bepublished covering the total results obtained in this district.
1 This paper is the sixteenth dealing with the results 1 if the Smithsi mian Bio-logical Survey of the Panama Canal Zone.2 Smithsonian Misc. Coll., Vol. Go, No. 2, 1912, p. [8.Smithsonian Miscellaneous Collections Vol. 60, No. 3

National Museum, Biologi-cal Survey Collection, from Mount Pirri (at 5,000 feet altitude),head of Rio Limon, eastern Panama ; collected March 5, 19 12, byE. A. Goldman (collector's number 15293).Distribution.—Known from type locality only.General characters.—Apparently most closely related to G. bour-cieri but entire top of head and nape rich rufous.Description of type.—Forehead cinnamon rufous shading intorich chestnut between eyes and thence into rich reddish chestnutover entire crown and nape ; upper side of neck dark olivaceous graystrongly washed with dark vinaceous ; interscapular area dark,slightly metallic Indian purple ; upper side of rump wings and tailbrownish chestnut darker and browner on scapulars ; rump and tail,with a slight vinaceous tinge over all ; exposed part of primaries andalula dusky gray ; sides of head below eyes from base of lowermandible to include ear coverts pinkish buff and bordered from billback along lower side of cheeks by a strongly marked black line
;
chin and throat. white shading posteriorly into vinaceous gray whichcovers under part and sides of neck and anterior two-thirds ofbreast ; posterior part of breast pale dingy gray finely maculated withpale huffy ; middle of abdomen dingy white ; sides of breast, Hanksand axillaries dark grayish grown ; under tail coverts like posteriorpart of breast but a little darker ; bill black ; feet and tarsus (in driedskin) dark red.Measurements of type.—Wing, 144; tail, 87; culmen, 16; tarsus,44.Remarks.—-This species is based on a series of five specimensall of which agree in the rufous crown and nape. It appears to be aforest species of the higher slopes of the Mount Pirri range whereit was plentiful.

National Museum, Biologi-cal Survey Collection, from Marraganti, in the lowlands 150 mileseast of Canal Zone, Panama ; collected April 4, 1912, by E. A. Gold-man.Distribution.—Known from type locality only.General diameters.—In colors and color pattern extremely close tochrysochlorus from Brazil but red on head a lighter shade; earcoverts paler olive; stripe from nostrils back along side of head andneck much richer golden, nearly orange yellow ; under parts of bodybarred with deeper and richer ochraceous yellow between duskybars ; rectrices olive green, dusky only along shafts and at tips in-stead of almost entirely dusky as in chrysochlorus; size larger.Description.—Entire top of head and nape bright poppy red, lesscrimson than in chrysochlorus; rest of upper parts including topof wings and upper side of tail, except the dusky brown shafts andtips of feathers, bright olive green ; a narrow line on lores, broaden-ing to include eyes, upper half of cheeks and auriculars light olivebrown, this area limited posteriorly by downward extension of red ofnape which touches upper border of a rich bright golden yellowstripe extending from nares back below cheeks and lower border ofauriculars and along sides of neck ; malar patch red like crown andcontinued posteriorly by a broad stripe of olive along sides of headand neck below the golden yellow stripe; chin and throat dullergolden buffy than in chrysochlorus ; rest of under parts narrowly butstrongly barred transversely with ochraceous yellow and olive, barsnarrowest immediately below yellow throat patch becoming broadestand palest yellow on abdomen and under tail coverts ; bend of wingplain buffy yellow, narrowly barred at base of primaries on top witholive and buffy yellow ; axillaries deep orange buff ; inner webs ofsecondaries and primaries entirely deep cinnamon buff basally butthis color gradually narrowing to a point on inner margin of innerwebs, reaching half way to tips of two first primaries and graduallyincreasing to near tips of inner webs of secondaries (in chrysochlorusoutside of bend of wing plain yellow ; cinnamon of inner webs ofprimaries and secondaries paler and extending three-fourths ormore of length toward tip of primaries) ; tail in present form olivegreen like back with dusky shafts and tips to feathers, in chrysoch-lorus tail almost all dusky.
4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60Measurements of type.—Wing, 123.5 ; tail, 69 ; oilmen, 23 ; tarsus,20. Measurements of adult male from Chapada, Matto Grosso,Brazil (American Mus. Nat. Hist.) : Wing, 117; tail, 71; oilmen,21 ; tarsus, 20.Remarks.—The present form bears a surprisingly close resem-blance to chrysochlorus of Brazil but tbere is a wide gap in theknown range of the species southeast of the present type locality.Only a single individual, the type, was seen at Marraganti duringGoldman's brief stay there.AULACORHAMPHUS C^RULEIGULARIS COGNATUS, subsp. nov.Mount Pirri ToucanType.—No. 232544, adult male, U. S. National Museum, Biologi-cal Survey Collection, from Mount Pirri (at 5,000 feet altitude)head of Rio Limon, eastern Panama; collected March 5, 1912, byE. A. Goldman (collector's number 15292).Distribution.—Known from type locality only.Subspecific characters.—Similar to A. cceruleigularis but top ofbill at base entirely black with no trace of chestnut colored areaabout nasal openings characteristic of that bird.Description.—Like cceruleigularis but black on base of bill ex-tends entirely across in front of nostrils completely replacing thechestnut area in front of nostrils of that form ; forehead greenishalmost like middle of back ; crown and top of neck slightly moreolive than forehead but much less olive than in cceruleigularis andless strongly contrasted with green of back ; blue band from eyeto throat along base of mandibles distinctly narrower in presentform ; size same as in cceruleigularis.Remarks.—The present bird is evidently also a close relative ofA. cyanolccmus from which it differs mainly in the restriction of theblack on the upper mandible. These toucans, including ccerulei-gularis, are probably all subspecies of the same bird ranging fromCosta Rica to Ecuador. The present subspecies is based on a seriesof seven specimens.MOMOTUS CONEXUS RECONDITUS, subsp. nov.Chestnut-bellied MotmotType.—No. 238084, adult male ( ?) , U. S.

NO. 3 NEW BIRDS FROM PANAMA AND VICINITY NELSON 5Distribution.—Known from Marraganti and Boca de Cupe, easternPanama.Subspecific characters.—Most like .1/. conexus from the CanalZone but much darker ; back dark olive green with a darker andmore chestnut-rufous suffusion; outside of wings darker green;under parts also much darker and more chestnut, especially onabdomen.Measurements of type.—Wing, 123; tail, 230; culmen, 37; tarsus,28.5.Remarks.—M. conexus and the present subspecies are muchnearer to M. subritfesceus than to lessoni. In fact it is almost cer-tain that when specimens from intermediate localities are collectedthey will show that conexus and reconditus are subspecies of sub-rufescens. The fact that conexus from the Canal Zone retains cer-tain distinctions of color pattern characteristic of subrufescens withno sign of intergradation toward lessoni is a strong indication of thespecific distinction of these birds. In M. lessoni the black ear patchis narrowly edged above and below by the same color as that on theforehead while in subrufescens, conexus and reconditus this earpatch is bordered above by the same color as that of the forehead andbelow by a much deeper and richer blue like that of the nape ; thesethree forms also agree in having the abdomen clearer rufous thanthe neck and breast which are distinctly greenish ; in lessoni thereverse of this distribution of color exists and the breast is morerufous and less greenish than the abdomen. M. c. reconditus isbased on two specimens, the type and one other from Boca de Cupe inthe same district.ELECTRON PLATYRHYNCHUS SUBOLES, subsp. nov.Darien MotmotType.—Xo. 232536, adult male, U. S. National Museum, Bio-logical Survey Collection, from Cana (at 2,000 feet altitude), easternPanama; collected March 9, 1912, by E. A. Goldman (collector'snumber 15336).Distribution.—Known from type locality only.Subspecific characters.—Size of E. p. minor but bill longer and nar-rower; rufous on head, neck and breast lighter and more buffy
;
green on back clearer and brighter than in either platyrliynchus orminor and upper side of tail bluish; abdomen blue.Description of type—Top of head and neck rnsty cinnamon-rufous paler than in minor; under side of neck and fore breast apaler and duller shade of same with an overlying tinge of green
6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60
a thin patch of bluish green on chin ; the usual black breast spot
;
lores and area under and behind eyes black ; back nearly grass green ;upper tail coverts bluish green ; top of wings mainly bluish green butouter borders of primaries distinctly bluish ; upper side of tail brightbluish green, varying to cyanine blue on ends of tail in certain lights,the blue on tail much stronger and clearer than in minor; a poorlydefined margin of bluish grass green about posterior border ofrufous on breast changing to cserulean blue with a greenish tinge onabdomen and a greener shade of same on under tail coverts. Billnarrower and longer than in minor and black to tip, thus lackingthe pale horn colored tip of latter.Measurements of type.—Wing, 116; tail, 177; culmen, 45; tarsus,17-Remarks.'—This subspecies differs strongly from E. p. minor,the most striking differences being in its long slender bill, palercolors and the distinctly bluish cast of the top of the wings and tailand the blue abdomen. The present bird agrees with minor in sizeand is thus much smaller than typical platyrhynchus. Hartert givesthe measurements of a typical specimen of the latter from Paramba,Ecuador, as follows: Wing, 130; tail, 223; culmen, 49; tarsus, 20.The bill of subolcs is actually as well as proportionately narrowerthan in either of the forms named above. This form is based on asingle specimen. GOETHALSIA,1 gen. nov.Apparently nearest Goldmania, the three or four middle undertail coverts being shorter than usual and specialized as in that genus,silky white in color and forming a tuft of overlapping or " nested "and strongly decurved stiff plumes about twice as long as in Gold-mania and more plume-like nearly to base of feathers ; other undertail coverts normal and differently colored from middle ones butproportionately smaller than usual ; this strong character present inboth sexes and in the young as in Goldmania; primaries mediumwidth, broader than in Goldmania, normal in all conditions ( ?) andouter primary distinctly longer than next one ; tail emarginate, nearlythree-fifths the length of wing ; bill slightly broadened and ridgedat base, terete elsewhere and same length as head ; nostrils operculate,feathering of forehead extending out about two-thirds of length ofEarned in honor of Colonel George W. Goethals, head of the PanamaCanal Commission, to whom the scientific workers of the Biological Surveyof the Canal Zone are deeply indebted for prompt and courteous assistance inprosecuting their work.

Color: Maleson head and body mainly plain metallic green above and below ex-cept buffy-rufous mask on chin and lores and buffy whitish onposterior abdomen; primaries purplish black; secondaries rufous,dark-tipped as in Eupherusa; tail feathers pale rufous buffy withexposed parts of middle feathers dark bronze green and same coloron tips of other feathers decreasing proportionately in width to a finenarrow margin on outer feather on each side.Type of genus Goethalsia bciia, sp. nov. (monotypic).GOETHALSIA BELLA, sp. nov.Goethals' Humming-birdType.—No. 238672, nearly adult male, U. S. National Museum,Biological Survey Collection, from Cana (at 2,000 feet altitude),eastern Panama; collected March 16, 1912, by E. A. Goldman (col-lector's number 15371).Distribution.—Known from extreme eastern Panama only, Cana(2,000 feet) and Mount Pirri (to 5,000 feet).Description of type.—Top of head dull dark bronze green shadinginto a brighter bronze green on neck and back and into golden bronzeon rump ; longer upper tail coverts dark coppery bronze ; lores andmalar area dark reddish rufous shading into reddish buffy on chin ;lower parts, from chin to include front of abdomen, clear brightmetallic green ; crissum buffy and buffy whitish, except tbree or fourmiddle under tail coverts which are much longer than other covertsand specialized into satiny white overlapping, rigidly decurved plumesas in Goldmania but much longer and broader, or more developedbasally ; sides of neck and body greenish bronze ; posterior flanksreddish buffy; primaries purplish black; secondaries rusty rufoustipped with dark bronzy purplish (similar to pattern of Euphcntsa) ;tail mainly rusty buffy but exposed parts of two middle feathersdark bronze green and lateral feathers tipped with proportionately,decreasing amounts of same to a narrow edging on tip of outerfeather on each side.Adult female.—Similar to male but smaller and under parts ofneck and body nearly uniform ochraceous buffy with metallic greenfeathers confined to sides of breast ; less dark bronze green on tailfeathers, two outer pairs entirely reddish buff}'.Measurements of type.—Wing, 52; tail, 29; culmen, 17.Remarks.—Although the wing characters are different in tbepresent bird from those of Goldmania the similarity of the curious
8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60
modification of the middle under tail coverts in the two genera,present in both sexes and in the immature plumage appears to indi-cate a close relationship. Unfortunately the only specimens of thepresent species are two slightly immature males and an adult female,so it is impossible to determine whether the outer primary of thefully adult male is or is not modified near the tip. Goldman collectedthe type of this new genus and species at Cana at an altitude of 2,000feet in March, and during the same month and in May collected twoothers on Mount Pirri at 4,500 and 5,000 feet altitude.
ERIOCNEMIS FLOCCUS, sp. nov.Wool-tufted Humming-birdType.—No. 238295, adult male, U. S. National Museum, Biologi-cal Survey Collection, from east slope of Mount Pirri (at 5,000 feetaltitude), near head of Rio Limon, eastern Panama; collected April12, 1912, by E. A. Goldman (collector's number 15488).Distribution.—Known from type locality only.Specific characters.—A plainly colored species resembling E.aurciicc in size and general color of upper parts ; lower parts muchgreener with gray borders to feathers, whitish abdomen and dingypinkish huffy leg-tufts, latter with a stringy, woolly appearance.Description of type.—Top of head dark green, clear and dull onforehead and changing on crown, nape and sides of head, and to a lessextent on neck, to greenish coppery bronze ; wing coverts a little richerbronze than sides of neck ; all of back to tail coverts clear brightmetallic grass green with a slight trace of bronze ; upper tail covertsbright rich golden bronze ; under parts, from chin to abdomen,clearer and more brilliantly iridescent green than back but with aslight wash of bronzy and feathers along under side of chin, neckand breast, except on sides, narrowly bordered with dull grayishwhite, giving a scaled appearance in certain lights ; white edging tofeathers increases posteriorly and leaves middle of abdomen dullwhitish ; under tail coverts green like feathers of breast and similarlyedged with grayish white ; leg patches more stringy and less puffedthan usual and dingy pinkish-buffy white in front, and more of adingy smoky buffy posteriorly ; wings purplish black, with a narrowrufous-buffy margin at bend ; tail dark steel blue-black, with a slightbronzing on middle feathers ; tail deeply emarginate.Description of adult female.—Similar to male but much more andclearer white on under parts, including broader edgings to feathers

of neck and breast and larger abdominal area ; outer tail featherswith small apical whitish tips.Measurements of type.—Wing, 61 ; tail, 385; culmen, 21.Remarks.—This species is based on eleven specimens from thetype locality. It appears to be quite distinct from the known mem-bers of the genus but has a close superficial resemblance on the upperparts to E. aurelicu but the colors are brighter than in that species,Its entirely buffy, and not very fluffy, leg puffs are a strong character.PH^THORNIS ADOLPHEI FRATERCULUS, subsp. nov.Brown Pigmy Humming-birdType.—No. 232530, adult male, U. S. National Museum, Biologi-cal Survey Collection, from Cana (at 2,000 feet altitude) easternPanama; collected Feb. 28, 1912, by E. A. Goldman (collector'snumber 15230).Distribution.—Known from type locality only.General characters.—Close to P. a. saturatus of western Panamaand Costa Rica but distinctly darker above and below, crown moresooty brownish, upper tail coverts darker and more chestnut andlight tips of tail feathers narrower. Although this form is based on asingle specimen it differs so strongly from the scries representingneighboring forms there is little doubt of its being distinct.THAMNISTES ANABATINUS CORONATUS, subsp. nov.Rufous-crowned AntshrikeType.—No. 238537, adult male, U. S. National Museum, Biologi-cal Survey Collection, from Cana (at 3.500 feet altitude), easternPanama; collected June 6, 1912, by E. A. Goldman (collector's num-ber 15845).Distribution.—Panama, from Veragua to the Colombian border,Subspecffic characters.—More richly colored than T. a. saturatus,with crown dull rufous contrasting with olivaceous brown of back,and under side of neck and upper breast dull ochraceous huffy. ntrasting with the olivaceous buffy of rest of under parts.Description of type.—Crown and nape dull chestnut rufous ; entireback brownish olive; top of wings, upper tail coverts and tail rustychestnut becoming browner on terminal half of wings from primariesto tertials ; concealed spot of bright orange rufous on back narrowlymargined posteriorly with black; chin, under side of neck and forepart of breast dei aceous buffy plainly contrasting with theolivaceous buffy of resl 1 E tinder parts which become paler along
IO SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60
median line and darker and more olive on sides ; sexes alike except ab-sence of concealed orange rufous spot on back of female ; size aboutas in saturatus.Remarks.—A series of sixteen T. a. saturatus from various CostaRican localities, including the type, agree in having the crown andback of practically the same color and in having the under parts ofneck and body nearly uniform. Five specimens from Calobre (Ver-agua), the Canal Zone, and Cana near the Colombian border, agreein having the crown distinctly more rufous than back and the underside of neck and fore breast ochraceous buffy contrasting with re-mainder of lower parts. The specimen from Calobre, Veragua,western Panama, in the U. S. National Museum is evidently thebasis for the statement by Mr. Ridgway that in T. a. saturatus thepileum is sometimes deep russet. As stated above this specimenbelongs to the present subspecies and is even darker and morestrongly marked than any of the other examples, including the type.DYSITHAMNUS MENTALIS SUFFUSUS, subsp. nov.Olive-sided AntvireoType.—No. 238043, adult male, U. S. National Museum, Biologi-cal Survey Collection, from Mount Pirri (at 4,000 feet altitude),eastern Panama; collected May 6, 1912, by E. A. Goldman (collec-tor's number 15676.)Distribution.—Known from upper slopes of Mount Pirri only.SubspeciHc characters.—Males most like typical mentalis but muchless yellow below, more as in septcntrionalis, pale grayish whiteof under side of neck extending farther back (over front of breast) ;sides, breast and body much, more extensively olive green, limitingthe yellow mainly to abdomen ; flanks dull olive green ; under tailcoverts dull yellow or yellowish buffy ; the female most like that ofsemicinercus from Bogota but top of head rather duller rusty andrest of upper parts more greenish olive (less tinged with brownish) ;breast and sides of body dingy brownish olive-greenish, becomingbrowner on flanks and buffy on under tail coverts ; abdomen lightyellow washed with brownish olive from sides ; size large.Measurements of type.—Wing, 62; tail, 40; culmen, 16; tarsus,19-5-Remarks.-—The type of D. m. septcntrionalis from Vera Paz,Guatemala, is a much paler and grayer bird than the large seriesfrom Costa Rica and western Panama which have been referred toit. Should more material from Guatemala show that this difference
NO. 3 NEW BIRDS FROM PANAMA AND VICINITY NELSON IIholds between the birds of the two areas the southern bird may re-quire separation as a distinct subspecies. The present form is basedon a series of ten specimens.HERPSILOCHMUS RUFIMARGINATUS EXIGUUS, subsp. nov.Rufous-winged AntvireoType.—No. 238539, adult male, U. S. National Museum, Biologi-cal Survey Collection, from Cana (at 3,500 feet), eastern Panama;collected June 6, 1912, by E. A. Goldman (collector's numberI5844)-Distribution.—Known from type locality and from Boca de Cupeat 250 feet above sea level on the adjoining lowlands.Subspccific characters.—Smaller than H. rufimarginatus withlarger bill ; the male differs in having a broad black band extendingas a continuation from black crown and nape down middle of backand rump, this black on back varied with a slight mixture of thebordering gray ; cheeks, chin and throat white without trace of yel-low suffusion ; female browner above and deeper yellow below.Description of male (type).—Top of head, back of neck and ex-tension of same in a broad band down middle of back and rumpblack, this black band varied by slight mixture of gray especially onthe front of shoulders ; sides of neck as well as sides of both backand rump gray ; broad superciliary stripe of dull white with fineblack edges to feathers ; blackish loral spot and black postocularstripe ; sides of head below eyes, chin and throat, dull white, feathersslightly margined with blackish and no yellow suffusion ; medianpart of breast and abdomen dull pale lemon yellow ; sides of breast andflanks much paler and grayer ; wings black with bright white ter-minal spots on coverts forming two wing bands, that on lesser covertsbroken, on greater coverts larger and more uniform ; two inner-most tertials strongly edged with white, other tertials, secondariesand primaries edged with rufous chestnut ; middle pair of tailfeathers dark gray with narrow black shaft line broadening sub-terminally and tipped with white ; outer pair of feathers black withterminal half of outer web and fifth of inner web white, other tailfeathers black with small white tips ; female with top of head andpostocular stripe chestnut; back and rump brownish olive gray; tailwith more white on tips and outer webs of all but inner two pairsof feathers than in male; wings and entire under parts similar tomale but deeper yellowish with a wash of pale huffy on sides ofbreast.
12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60Measurements of male {type).—Wing, 48; tail, 37.5 ; oilmen, 15 ;tarsus, 18.5.Remarks.—I have seen no specimens of H. r. frater, which wasdescribed from Sarayacu, Ecuador, but so far as the characters ofthis form are given in descriptions it appears to differ from the pres-ent form, although von Berlepsch and Hartert state that adult speci-mens from the Caura River have the interscapular region black, ap-parently as in the present form (Nov. Zool. 1902, p. 75). Goldmancollected only two specimens of this bird, a fine adult male and fe-male. GRALLARICTJLA FLAVIROSTRIS BREVIS, subsp. nov.Darien GrallariculaType.—No. 238069, adult male, U. S. National Museum, Biologi-cal Survey Collection, from Mount Pirri (at 4,500 feet altitude),near head of Rio Limon, eastern Panama; collected May 1, 1912, byE. A. Goldman (collector's number 15630).Distribution.—Known from upper slopes of Mount Pirri only.Subspecific characters.—Generally similar to typical ftavirostrisbut smaller with much larger bill ; upper parts with less brownishsuffusion, the crown more olive grayish ; back nearly plain olive andoutside of wings darker and more olive brown ; tawny ochraceousof under side of neck, breast and sides of body about the same, butwith black edgings to feathers usually well marked but narrower andless numerous on both throat and breast than in typical ftavirostris.Measurements of type.—Wing, 64; tail, 26; oilmen, 16.5; tarsus,24.Remarks.—This subspecies is based on four specimens, three ofwhich are much alike but the other lacks the dark edges to feathersnf neck and breast as in costaricensis, but the ochraceous of these
1 tarts is lighter and yellower, the upper parts greener and less brown-ish olive, and the size smaller with larger bill.MARGARORNIS BELLULTJS, sp. nov.Beautiful MargarornisType.— No. 238070, adult male, (J.

rest of under parts olive brown with numerous black bordered gut-tate white spots.Description.—Top of head and neck dull olive brown each feathernarrowly bordered with dusky ; back and lesser wing coverts burntumber with broad blackish shaft lines on wing" coverts, and obscurelymarked narrow dark shaft lines on back ; greater wing coverts andexposed parts of scapulars, secondaries, upper tail coverts and top oftail bright rufous chestnut, dullest on wings; greater coverts withblackish shaft lines; primaries edged externally with rusty brown,shaded with olive ; sides of head and neck, including malar region,brown like top of head and marked with a supraocular stripe ex-tending back to nape; ring around eyes and streaks along sides ofhead and neck pale yellowish white ; chin and throat white ; rest ofunder parts nearly uniform olive brown (with a slight tinge ofreddish on flanks, becoming stronger on under tail coverts) withnumerous bright yellowish white guttate spots sharply edged withblack, the spots largest along median line, smaller on sides and be-coming shaft streaks on under tail coverts ; posterior white marksof abdomen smaller and with slight or no dark margins ; inner websof secondaries and all but two or three outer primaries mainly richorange buff; inner side of wing at bend and axillaries pale buffywith black borders to feathers except on some axillaries, and undersecondary and primary coverts.Measurements of type.—Wing, 76; tail, 71 ; oilmen, 14.5; tarsus,20.Remarks.—This well-marked species is nearest perlata but appearsto be distinct from any heretofore described. The spots on the underparts resemble those of perlata but are much smaller and fewer andthe general color of the under parts is browner and less washed withrufous. On the back the two are very distinct. This species isbased on six specimens, all from Mount Pirri. In some specimensthe dusky shaft streaks on the back are much more prominent thanin others and one specimen has a few small scattered yellowish whiteshaft streaks on the posterior part of the neck or extreme !'n 1the back.

Specific characters.—Above dark olive greenish, darkest on topof head and on upper tail coverts ; wings and tail blackish slate colornarrowly margined with dull olive green ; lores and narrow ringaround eyes dingy yellowish ; sides of head olive green like back,under side of neck and breast dingy fulvous—almost olive—buffyshading into olive greenish on sides of breast and changing abruptlyinto canary yellow on abdomen and under tail coverts, yellow paleston tail coverts and darkest next breast ; bend of wing dark olivegreen ; axillaries pale dull yellowish ; bill dusky above yellow below
;
feet and tarsi dusky horn color.Measurements of type.—Wing, 62 ; tail, 49 ; culmen, 10 ; tarsus,12.3.Remarks.—The present species, represented in the collection byfive specimens, differs strongly from other known members of thegenus in the green back, light olive-fulvous breast and bright yellowabdomen, thus reproducing a style of coloration found in Empidonax.An immature specimen taken at the type locality, March 13, has con-spicuous dark buffy edgings to the wing coverts, forming two wingbars ; narrow grayish white edgings to outer borders of tertials andsmall buffy gray tips to points of tail feathers. In the adult thewings and tail are plain, or with scarcely a trace of edgings to thefeathers. This species appears to be most closely related to M.olivaccus Berl. & Stolz. of Central Peru but is distinguished by theclearer yellow of the abdomen and other characters.PRJEDO, 1 gen. nov.Generic characters.—Small flycatchers closely related to Aphano-triccus Ridgway, but with a strong resemblance in coloration toEmpidonax; bill proportionately broader and much thinner or moreflattened than in Empidonax, broad and depressed at base with well-marked ridge along top ; outline of sides slightly convex subbasallv ;compressed and hooked at tip with a well-marked notch ; rictalbristles fine and weak extending along top of upper mandible three-fourths its length ; nostrils open, rounded and set well forward onmandible (about one-third of distance from feathering of foreheadto tip) ; under mandible slightly keeled with broad rounded inter-ramal area extending forward as far as anterior border of nostrils;point of wings short, longest primaries only a little more than halfthe length of culmen longer than secondaries ; tenth or outer pri-mary equals third and also equals the longest secondaries ; ninth pri-

Specific characters.—Close to II. Havicollis but smaller with yellowareas a rich dark cadmium yellow.Description of type.—Top and sides of head, including ear coverts,top and sides of neck, anterior half of back, top of wings and uppertail coverts dull black, of a more intense or less sooty shade than intypical flavicoUis; chin, sides of head up to lower border of eyes,fore neck, under tail coverts and posterior half of back, includ-ing rump, rich dark cadmium yellow ; under side of body white,nearly pure along middle and grayer on sides ; indistinct and partlyhidden black bars on whitish feathers immediately back of yellowarea on upper breast ; axillars and basal part of inner webs of pri-maries and secondaries pure white.Measurements of type.—Wing, 66; tail, 48; culmen about 1 1.5(broken) ; tarsus, 16.5.Remarks.—A nearly mature male collected by Goldman at Cana,eastern Panama, May 22, 19 12, agrees with the type in the intensecadmium color of the yellow areas except the under tail covertswhich are mainly lemon yellow but contain new cadmium coloredfeathers showing the paler color to be a mark of immaturity. Twospecimens of this subspecies examined.VIREOLANIUS EXIMIUS MUTABILIS, subsp. nov.Panama Shrike VireoType.—No. 238507, adult female, U. S. National Museum, Bio-logical Survey Collection, from Cana (at 3,000 feet altitude), easternPanama; collected June 11, 1912, by E. A.

NO. 3 NEW BIRDS FROM PANAMA AND VICINITY—-NELSON 21yellow about like chin and throat ; in type of eximius the under partsare a nearly uniformly darker greenish than in the present form.Measurements of type of eximius (sex?).—Wing, 75; tail, 48.5;culmen, 19; tarsus, 21.Measurements of type of mutabilis (ad. J)—Wing-, yo ; tail, 44;culmen, 17.5 ; tarsus, 21.5. Owing- to the sex of the type of eximiusbeing unknown it is impossible to decide whether the differences insize shown in these measurements are due to sex or not.Remarks.—Through the courtesy of Mr. Witmer Stone, Curatorof Birds in the Philadelphia Academy of Natural Sciences, I havebeen able to make direct comparison with the type of eximius. Itwas formerly mounted and shows some signs of fading, but the re-tention of the yellow practically unchanged on the superciliary stripeand chin and its absence on the abdomen and under tail coverts indi-cate that it never existed on these last named parts, and thus differsstrongly from the present form in this character as well as in therestricted area of yellow on the chin and throat. The back of thetype of mutabilis is more bluish green than in the type of eximiusbut this may be due to fading in the latter. From the foregoing itappears that notwithstanding any fading that may have occurred inthe type of eximius the present form differs from it sufficiently to berecognized as a geographic race. The type is the only specimenseen by Goldman and these birds are apparently scarce in easternPanama.BASILEUTERUS MELANOGENYS IGNOTUS, subsp. nov.Mount Pirri WarblerType.—No. 232972, adult female, U.

Goldman (collector's number 15539).Distribution.—Known from type locality only.Subspccific characters.—In general similar to typical meianogenys,but superciliary line pale greenish yellow and broader in front whereoccupying most of forehead ; lores black but remainder of sides ofhead and chin pale greenish yellow (like under side of body) finelyflecked and mottled with black, the black heaviest on malar regionand immediately below eyes ; back distinctly greener and under partswith a stronger greenish yellow suffusion ; size smaller with pro-portionately larger bill.
22 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60Measurements of type.—Wing, 56; tail, 56.5; culmen, 12; tarsus,20.Remarks.—This form is based on a single specimen which is sostrongly characterized by the yellow superciliary line, restriction of •black on the sides of the head, and much more greenish back and yel-lower under parts that it evidently represents a well-marked sub-species.

Description of type.—Entire upper parts, including a broad post-ocular streak, tops of wings and tail tawny brown : wings indis-tinctly barred with dusky brown ; top of tail feathers with transverseseries of small dusky spots and imperfect bars more regularly placedthan in ochraceus; lores, chin and sides of head below eyes frommalar region back to include lower two-thirds of ear coverts andlower part of sides of neck bright ochraceous but not so rich as inligea; supra- and postocular streak, ending abruptly at posteriorborder of ear coverts, ochraceous burly ; middle of throat, under sideof neck and breast dull ochraceous buffy; abdomen dull white; siiof breast and flanks ochraceous brown ; under tail coverts dullochraceous indistinctly and irregularly barred with dusky.Measurements of type.—Wing, 44 ; tail, 27.5 ; culmen, 14.5 ; tarsus,Remarks.—Although the present species is much like ochraceusyet owing to the two species belonging to high mountain areas widelyseparated by lowlands it is probable that intergradation does notoccur. Goldman only secured a single specimen and saw one otherduring his stay of nearly a month on Mount Pirri so they appearto be uncommon. The present bird is much less reddish fulvous thanT. ochraceus ligea from Chiriqui and differs from it more than fromtypical ochraceus. Compared with T. solstitialis paliidipectus ofwestern Colombia festinus is smaller, with longer bill and brightermore reddish ochraceous on sides of head and neck and upper partsof head and body, and less strongly marked bars on wings and tail.MYADESTES COLORATUS, sp. nov.Varied SolitaireType.—Xo. 232601, adult male, U.
