CHILONYCTERIS. 39 
In the first genus, Chilonycteris, the nose-leaf is very little developed, being repre- 
sented by a wart on the top of the broad abruptly-truncated muzzle; a large portion of 
the lower lip, however, is deflected and covered with warts, which extend towards the 
angles of the mouth. The crown of the head is moderately elevated, the ears pointed 
and connected at their base; and the second lower premolar is very small. Several 
species are known, of which three have been found in Central America :— 
1. Ch. personata. Lower third of inner margin of ear-conch thickened and 
divided by a notch from the upper two'thirds. Forearm 175. Fur brown, 
lighter beneath. 
2. Oh. rubiginosa. Lower third of inner margin of ear-conch not thickened, con- 
tinuous with upper two thirds; a transverse rounded projection on the 
muzzle. Forearm 2-45. Fur variable, rusty-red to blackish-brown. 
3. Ch. davyi. As in last species, but the wing-membranes attached along the 
spine instead of to the flanks; back behind the shoulders naked. Forearm 
1"°85. Fur dark reddish-brown. 
Owing to the peculiar attachment of the wing-membrane, the last species has been 
made the type of a distinct genus, Pteronotus of Gray*; but it does not appear to 
differ from the rest in any other respect. 
Nothing has been recorded of the habits of the species here described; but Mr. 
Osburn has given an account of those of their West-Indian congeners, Ch. macleayi, 
Gray, and Ch. parnelli, Gray +. Their food appears to consist principally of Coleoptera.

Hab. Guatemata (Mus. Berol.?).—Venezvena?; Brazil. 
Among the Bats collected in Brazil by Natterer, and described after his untimely 
death by Wagner, were the present and the next species, each of which has since proved 
to range considerably to the northward. Ch. personata goes at least as far as Gua- 
temala, whence there is a specimen in the Berlin Museum?; but it is probably not 
abundant there, no examples being found in Mr. Salvin’s large collections.
