48 CHIROPTERA. 
The Stenoderma cinereum of De Blainville’s ‘Catalogue Anatomique du Muséum * 
was first described and figured by Gervais?. Subsequently it was independently de- 
scribed by M. de Saussure?; but his S. tolteca has been identified with Gervais’s 
species by Mr. Dobson after a comparison of Mexican examples with the type in the 
Paris Museum?. 
14. VAMPYROPS. 
Vampyrops, Peters, Monatsb. Ak. Berl. 1865, p. 356. 
This genus is very closely allied to the last, but differs in its comparatively longer 
muzzle and in its dentition. There are two premolars and three molars on each side 
above and below; and these are divided into two longitudinal portions somewhat as 
in the genus Sturnira (p. 50). The two known species agree in coloration, being 
marked with white stripes on the head, and having a median white line down the back, 
but may be easily recognized by the following characters :— 
1. V. lineatus. Forearm 1-65. Fur extending on the membrane at least as far 
as a line drawn from the elbow to the knee; dark brown above, ashy-brown 
beneath, four broad white streaks on head, and one down back. 
2. V. vittatus. Forearm 2'-35. Fur not extending on the membrane beyond a 
line drawn from the elbow to the middle of the femur; dark brown, white 
stripes narrow. 
1. Vampyrops lineatus.

The smaller, and apparently the most widely distributed, of the two species of 
Vampyrops has a range extending from Paraguay to Mexico. Two specimens collected 
in the latter country by Dr. Heller, and preserved in the Vienna Museum, were 
described as a distinct species, V. hellert, by Professor Peters, who considered that they 
differed from V. lineatus in their smaller size and in the greater extension of the fur on 
the flying-membrane. He has lately informed me, however, that he now only regards 
them as representing a smaller variety of the present species.
