Geoffroy Saint Hilaire,* under the above name, with the exception of a slight 
difference in the dimensions ; I will, therefore, add those of the present specimen, 
which is a female. It may be observed, that in the animal before me, the tragus 
of the ear is pointed, and not bifid at the apex, as represented in plate xi of the 
work quoted.

“ This bat was caught at Bahia, (latitude 13° S.) on the coast of Brazil, 
in consequence of its having flown into a room where there was a light. I

Description. — In size and colouring, this Bat very closely resembles the Ves- 
pertilio Pipistrellus of Europe ; the wings, however, are considerably broader 
in proportion ; the antibrachium, tibia, and tail, are each of them longer ; the 
tragus of the ear is also longer, and narrower. 
The muzzle is short and obtuse, and furnished on each side with numerous 
hairs, which, when compared with those of other parts, are of a more harsh 
nature. The nose is naked at the apex. The forehead is concave. The 
ears are narrow, and somewhat pointed, emarginated externally, and have 
about four transverse rugae : the tragus is elongated, narrow, and pointed, and 
has the outer margin very obscurely crenulated. On the chin there is a 
small wart, from which spring several stiffish hairs. The tail is about equal 
to the body in length, and has the extreme tip free. The fur is moderately
