Till recently the only known example of this curious Bat was M. de Saussure’s type, 
which was captured on the Volcan de Orizaba close to the snow-line!. Unfortunately 
the skin of this unique specimen was lost, and the skull only was available for examina- 
tion by Professor Peters?. Mr. Dobson, however, has been fortunate enough to find two 
perfect specimens preserved in spirits in Mr. Salvin’s Guatemalan collections in the 
British Museum, and has thus been enabled to give a complete description of its 
external characters; from one of these examples our illustration is taken. 
11. GLOSSONYCTERIS. 
Glossonycteris, Peters, Monatsb. Ak. Berl. 1868, p. 364. 
This genus agrees with the next and with the West-Indian Phyllonycteris in the 
imperfect ossification of the zygomatic arch, which is consequently wanting in the 
prepared skull—a peculiarity not found in any other known Bat. In Glossonycterys 
the molars present a well-marked W-pattern, the very short interfemoral membrane is 
hairy both above and below, and the tail is externally absent. The only recognized 
species is dark brown above, greyish-brown below; and its forearm measures about 
1:65.

M. De Saussure having sent the Mexican Bat which he had called Anura ecaudata? 
to Professor Peters, it was determined by that zoologist to be a new species +, though 
he thinks that it may possibly be identical with Tschudi’s Cheronycteris peruana?. 
The type of this latter is unfortunately lost ; and as the original description and figure 
are insufficient for exact determinations, Mr. Dobson, finding that the type of Gray’s 
genus Anoura' belongs to this species, has adopted his trivial title of geoffroyi>. But
