56 Mr. O. Thomas on 
the face more than in Glossophaga, less than in Charonycteris, 
the general form being also intermediate between these two. 
Zygomata absent. Bony palate extending backwards almost 
to the level of the most anterior point of the glenoid facets. 
Nose-leaf as in Glossophaga, but shorter. Ears and tongue 
as in that genus. Interfemoral membrane well developed, 
equal to that of Cheronycteris. Wings to the terminal part 
of the metatarsals. Calcar distinct. 
This genus adds another to the group of Glossophagine 
bats, of which there are now eight genera, all closely allied 
and only distinguished from each other by the various propor- 
tions in which they divide some half a dozen characters. The 
cheek-teeth range from 4 to 6 above and 5 to 6 below; but 
it is not always quite easy to tell whether, when the number 
is below 8, the missing teeth are premolars or molars. On 
the whole, in the present case it seems fairly clear that the 
missing teeth above are the anterior premolar and the poste- 
rior molar, and that the latter tooth is missing below. This 
would make the formula as above given and similar to that of 
Leptonycteris. 
On the whole, important as the number of teeth may seem 
to be, { am inclined to consider Lichonycter’s most nearly 
allied to Cheronycterts, from which, as from Glossophaga, 
Monophylius, Lonchoglossa, and Anura, it differs by the 
reduction of its cheek-teeth to the number possessed by 
Leptonycteris. Phyllonycteris has the same total number in 
the lower jaw, but they have been differently assigned to 
molars and premolars (P. 5, M. 3), a point on which J can at 
present express no opinion. 
Lichonycteris obscura, sp. n. 
Size and general appearance of Glossophaga soricina. 
Nose-leaf about equally high as broad. Ears short, evenly 
rounded off above, their outer margin concave below the tip 
and notched again below opposite the tip of the tragus, 
Antebrachial membrane mostly naked above, but the basal 
third of the forearm is thickly clothed with fur, and some of 
this extends on to the membrane ; metacarpal bone of thumb 
hairy ; rest of wings naked except along the sides of the body 
to a line from the middle of the humerus to the middle of the 
femur. Interfemoral membrane extending to the level of the 
end of the tibiz, its upper surface naked. Tail reaching to 
the level of the knee, its tip appearing on the upper surface of 
the membrane. Below, the antebrachial membrane is hairy, 
as is the basal third of the forearm, and the wings between 
the humerus and the flanks.
