In size this species is intermediate between J', carolinensis and V. snbidatns. The 

 ear is nuked, less rounded, and more pointed than either of the other ch)sely allied 

 species. The tragus is very narrow, linear, and less than half the length of the ear. 

 The tail is inclosed in the interfemoi-al memhrane, except the penultimate joint, 

 which is free. The anterior upper fore teeth, instead of being sub-simple, as in the 

 , V. carolinensis, or bilobate, as in V. suhulatus and F. montanus, are simple. 



Color. — The nose, upper lip and upper jaw are black; Wings dark brown. The 

 back is sooty browu; on each shoulder, at the insertion of the w^ing, there is a cir- 

 cular black spot about 4 lines in diameter; on the under surface cinerious brown. 



J)imensions. — Length of head and body, 2 inches 5 lines; length of tail, 1 inch; 

 length of spread, 8 inches 8 lines; height of ear posteriorly, 4 lines; height of tragus, 

 If lines.

 brane, which is naked; feet very small; toes short and slender; nails sharp and 

 much curved; hair soft and downy. 



Color. — The ears, wings, and interfemoral membrane are black. The fur on the 



ba<'k is black from the roots to near the extremities, where it is so slightly tipped

Californian hat. — With long silky bairs; tragus more than half the length of the

Description. — Anterior upper fore teeth bilobate. Head small; nose sharp; ears 

 of moderate size; erect, rather narrow, and pointed. Tragus linear, attenuated. 

 Wings of moderate length, which together with the ears are naked. Interfemoral 

 membrane with a few scattered hairs; feet small; nails slightly hooked. Tail pro- 

 jecting a little beyond the interfemoral membrane. 



Color. — The pelage, which is unusually long for the size of the body, and very soft 

 and glossy, is, on the upper surface, dark plumbeous from the base, and broadly tipt 

 with light yellowish brown; on the under surface the color is a little darker, owing 

 to the outer extremities of the hairs being more narrowly edged with the prevailing 

 color on the back, exhibiting the darker shades beneath. The ears and tragus are 

 blackish — the nose, chin, wings, and interfemoral meml)rane dark brown. 



Hah. — We have obtained but a single specimen, which Avas cajitured at California.
