THE FAMILIES AND GENERA OF BATS.

the crown of the inner tooth is longer in proportion to its height, less 
oblique on cutting edge, and less concave posteriorly; the second 
upper molar is narrower on lingual side; the lower incisors are 
slightly smaller and more widely spaced, and the lower premolars are 
broader in proportion to their length. Skull (fig. 25) with rostral 
portion relatvely broader than in Phyllonycteris poeyi , and palate 
wider anteriorly. Between Reithronycteris and Phyllonycteris there 
appears to be no tangible difference in the tongue, though both are 
readily distinguishable by this character from Erophylla.

Type-species. — Phyllonycteris bombifrons Miller. 
Geographic distribution . — Bahama Islands and Greater Antilles. 
Number of forms . — Four species of Erophylla have been described : 
E. bombifrons (Miller), E. planifrons (Miller), E. santacristobalen- 
sis (Elliot), and E. sezekorni (Gundlach). 
Characters . — Like Phyllonycteris , but calcar distinct, though short, 
inter femoral membrane extending to calcar, noseleaf with upright 
portion represented by an evident, pointed, median projection; skull 
with zygomatic arches complete, and lower molars all distinctly 
cuspidate and with noticeable cutting edge. Incisors, canines, and 
lower premolars essentially as in Phyllonycteris , except that pm 4 
is relatively larger and much more noticeably concave on inner sur- 
face. Upper molars (Plate IX, fig. 2) differing from those of Phyl- 
lonycteris in the greater height and more trenchant character of the 
outer main cusps and the more distinct concavity of the crowns. In 
m 1 and m 2 there is no trace of the rudimentary mesostyle. First 
lower molar with a low, but distinct, posterior cusp, and an outer 
slightly trenchant ridge high enough to cause the concave surface to 
be directed somewhat inward. Second and third lower molars like 
first, but considerably shorter, the anterior and posterior cusp rela- 
tively more developed and their cutting edge near middle of crown 
instead of at outer border. 
Species examined . — I have examined all the known species. 
Remarks .- — This genus is well differentiated from Phyllonycteris 
by the structure of its calcar and interfemoral membrane and by its 
distinctly cuspidate second and third lower molar. The species are 
also distinguishable from Phyllonycteris poeyi by the sharply pointed
