Californian Bat. — With long silky hairs ; tragus more than half the 

 length of the ear; color light yellowish-brown. 



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 projecting a little beyond the inter- 

 femoral menibrane. 



Color. — 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 tipped 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 membrane dark brown.
