CHIROPTERA. 205 
The range of this species extends, according to Mr. Dobson, “ from New York to the 
Rocky Mountains, and southwards to New Orleans and to the West-Indian Islands 
(Cuba)”*. Dr. Allen mentions two specimens from Matamoras as included in the 
Berlandier collections, which Lieut. D. N. Couch purchased and presented to the 
Smithsonian Institution; and there is a skin in the British Museum said to be from 
Central America‘. 
ATALAPHA (p. 22).

A specimen of the frantzii variety of this species was taken by Mr. Forrer in the 
Tres Marias.—O. T.]

As I observed above, this Bat being found at least as far south as Matamoras, 
according to the limits now adopted it must of course be accepted asa member of 
our fauna. 
Atalapha intermedia is the type of Professor Peters’s subgenus Dasypterus ?, charac- 
terized by the possession of only one upper premolar on each side, and by the inter- 
femoral membrane being hairy on its anterior half or two thirds only. From the two 
other members of the subgenus, A. egregia, Peters, and A. ega (Gervais), it may be at 
once distinguished by its olive-brown fur, its obtuse and curved tragus, and by its 
interfemoral membrane being naked on its posterior third only. Its forearm measures 
about two inches. 
VESPERTILIO (p. 23). 
In 1866 Dr. H. Allen published some “ Notes on the Vespertilionide of Tropical 
America” *, In this paper he gave provisional names to several specimens in the Museum 
of the Smithsonian Institution which appeared to him to be new, observing that, ‘‘ should 
any or all of them prove to be old species, their descriptions can, without confusion, be 
added to the original meagre diagnoses, and may thus add to what little we know of 
these obscure animals.” Of the genus Vespertilio three of these species were described 
* Proc. Ac. Philad. 1866, pp. 279-288.
