1893.] MR. O. THOMAS ON MAMMALS FROM CENTRAL PERU. 335 



premolars only |, the anterior one above perhajps lost, and not 

 really absent normally. Lo\yer incisors 4. 



Measurements of the type, an aged female in alcohol : — Forearm 

 34-5 mm. ( = 1-35 in.) ; head and body 46; tail 28; head 18; ear from 

 notch 14-5; both ears, tip to tip across head, 2-5"5 ; tragus 4; 

 metacarpus of third tiiiger 35, of iifth 22 ; lower leg 8 ; hind 

 foot 7. 



Hah. Central Peru. 



This interesting little species differs widely from any of the 

 previously knoA^ii Xeotropical Nuctinomi, and seems to approach 

 some of the members of the group called Mormopterus by Peters, 

 notably in the exti-eme reduction of the keel of the ear-conch, and 

 in the absence of the upper anterior premolar ; in fact, of all the 

 known species, the Austrahan N. norfolcensis. Gray, appears to 

 resemble it most nearly, although whether this resemblance really 

 amounts to relationship, I am not at present prepared to say. 



It is with great pleasure that I connect with this new Bat the 

 name of its disco\erer, M. Kalinowski, to \Ahose la.bours we owe 

 the valuable collection of small Mammals described in the present 

 paper.

As the synonymy shows, Dobsou and Alston liaA^e each thought 

 it necessary to use a different name for this species, different 

 both from each other and from that of the original describer, 

 Gray. On reviewing the whole case, it appears to me that Dobson 

 was right in considering the species named yeoffroyi sufficiently 

 characterized by the diagnosis given by Gray under the generic 

 heading of " Anoura," A. yeoffroyi being the only species. This 

 being the case, it is also clear that Anura must be used for the 

 genus, as the name had not been previously used in a generic sense 

 in zoology. For both genus and species, therefore, I use the 

 earliest name, verified as the identification is by the existence of 

 Gray's type specimen. 



The occurrence of this species in Peru confirms the reported 

 identity of Tschudi's " Choeronycteris peruana" with it.
