-J 6 4 ON BATS FROM THE GOTTINGEN MUSEUM. [June 15, 



The presence of a single specimen in a collection labelled " Popayan " 

 is, of course, not sufficient grounds to extend the distribution of this 

 species to the Neotropical Region, the Chiroptera of which (with one 

 exception only, Vespentf/o serotinus, as I have shown ^) are quite 

 distinct from those of any of the zoological regions of the eastern 

 hemisphere. There are, however, in the same collection several 

 other specimens of species, evidently Neotropical, which are labelled 

 "Popayan" (to be referred to hereafter), and with which this speci- 

 men agrees precisely in the state of preservation. It is also note- 

 worthy that F. maurus has been found in Europe at very high ele- 

 vations only along the Alps; and in this respect the South-American 

 habitat given agrees very well, for Popayan is situated in an elevated 

 plain in the Andes, 6000 feet high. 



If, then, specimens of this species have really come from such 

 very distinct and distant zoological regions, and exhibit so few 

 differences, it becomes evident that we must consider the Oriental 

 representative of this species, described under the names Vesperuc/o 

 mordax, Ptrs., and V. austenianus, Dobson, as a distinct species, 

 which, although agreeing remarkably in general structure, and 

 even in the colour of the fur, with V. maurus, differs in its con- 

 spicuously greater size (forearm 1"'6), in the very shallow eniar- 

 gination in tbe upper half of the outer margin of the ear-conch, in 

 the considerably less degree in which the extremity of the tail pro- 

 jects from the interfemoral membrane, and in the much greater 

 development of the first u[)per premolar, which, although the second 

 premolar is also close to the canine, may be seen without difficulty 

 from without. 



Vespertilio nigricans, Wied. 



Two specimens referable to this species, one from Cordova, Ar- 

 gentine Republic, the other from Popayan, U.S. of Columbia. The 

 latter, an adult male, has the forearm I'S inches long, and the digits 

 proportionally longer, but in other respects quite agrees with speci- 

 mens from other localities in which the forearm rarely exceeds 1"35 

 inch. Can it be that individuals of this and of other species inha- 

 biting very elevated regions have larger wings to compensate for the 

 very rarefied condition of the atmosphere ?
