Dentition as in A. noveboracensis. Size larger; length 4 to 5.50; tail 2 
2.33 ; extent 10 to 15 inches, averaging 12 to 14; ear .33 to.50. Lips and 
ears marked with black ; body colors rich chocolate-brown, or smoky-fawn 
color, overlaid with white, giving a brilliant, hoary appearance. 
This is the only Bat known to inhabit the northern regions, as ob- 
served hy Kennicott. It is distributed over North America at large, but 
is most abundant in elevated regions and northern latitudes. Since 
1823, it has generally been known by Say’s name, V. pruinosus. Major 
LeConte showed it to be identical with V. cinereus, Beauvois, and restored 
the prior name. 
Mr. F. W. Langdon informed me that a specimen of this Bat, in the 
collection of the Cincinnati Society of Natural History, was captured at 
Coal Springs, Kentucky, three or four miles from Cincinnati. 
Atalapha (Nycticejus) crepuscularis, (LeConte) Coues, may occur in southern 
Ohio, as it is reported from Pennsylvania to Missouri, and south-west.

* Molar teeth multicuspid, with the cusps connected by deep re-entering ridges, which 
describe two elongated triangles, and with at least one extensive antero-internal 
ledge. Skull with the calvarium wide; broadest about the periotic region, with 
the foramen magnum sub-cireular or oblong; the occipital condyles variously di- 
vergent, with the par-occipital processes obsolete or wanting. Pelage very soft. 
(Soricoidea as opposed to EHrinaceoidea.)
