Dentition :— 
1S, Cy pees Max 234 
Inner upper incisors conspicuously larger and longer than 
the outer ones, much thrown forward, broadly spatulate, close 
together, outer ones small, pointed, conical. Upper pre- 
molars and molars about as in Glossophaga, though markedly 
longer horizontally; last premolar with a well-defined in- 
ternal lobe. Lower incisors not deciduous, more or less 
overlapping one another, broad, with sharp indistinctly trifid 
edges. Lower cheek-teeth long and narrow, not overlapping, 
with small gaps between the premolars. 
Type LZ. mordaz, sp. n. 
This genus is no doubt nearly allied to Glossophaga, but 
may be distinguished by the absence of the zygomata and 
the unusual size and projection of the median upper incisors. 
From the development of these teeth and the size and per- 
sistence of the lower incisors it is evident that the tongue is 
less predominant at the expense of the incisors than is the 
case in the more specialized members of the group. 
Lonchophylla mordax, sp. n. 
General external appearance, 80 far as can be judged by 
skins, exactly as in Glossophaga soricina, except that the 
colour averages paler. The typeis near “ cinnamon-brown ” 
above, the bases of the hairs whitish, and “¢ wood-brown”’ 
below, but there is some variation in tone, and the darker 
specimens are quite as dark as the paler examples of Glosso- 
phaga obtained at the same place. 
Chin apparently without the usual deep central groove, but 
as all the specimens are skins, with the skulls extracted, this 
point is not exactly determinable. 
Ears rather more decidedly concave in the upper half of 
their outer margins than in Glossophaga. Noseleaf longer, 
the upper part of the lancet more sharply triangular, its sides 
evenly slanted, not concave. Proportions of limb-bones as 
shown by the measurements below. Size (apart from the 
very different length of head) and other characters as in 
Glossophaga.
