Genus LONCHOPHYLLA Thomas. 
1908. Lonchophylla Thomas, Ann. and Mag. Nat. Hist., 7th ser., XII, p. 458, 
October, 1903. 
Type-species. — Lonchophylla mordax Thomas. 
Geographic distribution. — Brazil and Venezuela. 
Number of forms. — Two species of Lonchophylla are known. 
Characters . — Like Glossophaga , but zygomatic arch incomplete; 
inner upper incisor higher than wide and more than double the bulk 
of outer tooth, which stands by itself near middle of space between 
large incisor and canine; lower incisors with narrow trifid cutting 
edges, the outer separated from canine by a space nearly equal to the 
length of its crown ; and last upper molar nearly as large as either of 
the others, its parastyle short. 
Species examined. — Lonchophylla mordax Thomas and Z. tlxomasi 
J. A. Allen. 
Remarks.— This genus is well characterized by the incomplete 
zygomatic arch, and by the form of the incisors both above and below. 
Externally it resembles Glossophaga.

phaga , but upper incisors much smaller and of equal length, the outer
