DESCRIPTION OF A NEW SPECIES OF BAT OF THE GENUS CAROL- 

 LIA, AND REMARKS ON CAROLLIA BREVICAUDA.* 



Harrison Allen, m. d. 



Carollia is one of the most common of the South American leaf-nosed 

 bats. Notwithstanding its wide range of distribution (it is found from 

 Mexico to the southern limit of Brazil, in.chiding the Antilles), the type 

 of the genus is that of the single species also. 1 have recently' examined 

 this form — Carollia hreHcauda — with the object in view of determining 

 whether or not an exampU' of Carollia in the collections of the National 

 Museum might prove to be new. 



The facts which led me to sui)pose that this might be the case were 

 the following: 



The specimen was smaller than C. brevicauda ; the color was of a light 

 chestnut-brown tint, instead of the ashy shade of G. brevicauda. The 

 interfemoral membrane was not incised. The nose-leaf was relatively 

 small, delicate, with entire, rounded nostrils, and the lower border 

 sharply defined to a point near the median line, where a small naked 

 space alone was seen. 



I have had a knowledge of these facts for a long time, but I hesitated 

 to describe the form as new, for in general appearance in the propor- 

 tions of the membrane, in the form of the ear, in the markings of the 

 wing membranes, and the shapes of the terminal phalanges the two 

 forms appeared to be essentially the same. I had but a single speci- 

 men — a young male from Costa Eica. I concluded that before describ- 

 ing it an examination of all the specimens of Carollia should be made. 

 A large number of specimens of the genus were available for the pur- 

 pose from the coll«^tions of the Museum of Comparative Zoology, but 

 unfortunately nine only of the twenty-six examples were in good con- 

 dition. 



From among these a young male was found, and I was thus able to
