BOIGA IRREGULARIS (Brown Treesnake). USA: COMMON
WEALTH OF THE NORTHERN MARIANA ISLANDS: Rota: Rota
Seaport (14.136502°N, 145.135351°E; WGS84). 3 September
2014. Shelwyn Taisacan, Robert Ulloa. Verified by G. Zug. USNM
581745. Snake (42 g, 810 mm SVL,1020 mm total length) captured
in a mouse-baited trap hung on the fence perimeter of the Rota
Seaport. Because the Northern Marianas Islands are historically
snake-free, these traps are used around ports and airports for
early detection of snakes that may stow away in vessels or aircraft
from Guam (60 km to the south), possibly evading quarantine
detections. Necropsy revealed no prey items in stomach or gas
trointestinal tract. Dissection at USNM confirmed the snake was
female. To our knowledge, this is the first incursion of a live Boiga
irregularis on Rota. Brown Treesnakes previously observed on
the island (N = 3) arrived in cargo already dead. The USGSBrown
Treesnake Rapid Response Team mobilized 4 September-20 Oc
tober 2014 to search the focal and surrounding areas for evidence
of a possible incipient population; no additional snakes were
found during this search effort.

CROTALUS CERBERUS (Arizona Black Rattlesnake). USA: ARI
ZONA: Mohave Co.: Cerbat Mountains ca. 1.2 km SE of Cherum
Peak (35.395166°N. 114.125314°W; WGS 84), 1905 m elev. 5 July
2014. Z. R. Mocarski. Verified by George Bradley. University of
Arizona (UAZ 57610-PSV. photo voucher). This specimen rep
resents the first vouchered report from the Cerbat Mountains.
Previously, this species was known from this range only from un
confirmed reports (Jones et al. 1985. Oecologia 66:595-601). This
specimen represents a ca. 25-km range extension to the north
west from the closest known locality in the Hualapai Mountains.
No suitable habitat exists between the two ranges. Rather dian
chaparral, a habitat type frequented by this species, Mohave
desert scrub prevails in the lowlands separating the Cerbat and
Hualapai mountain ranges. Specimen observed at 1600 h.
