258 ON THE GLOSSOPHAGINZ. 
Notes on the Skeleton.—Ribs thirteen ; first costal cartilage not wider than the rib. 
Humerus with pectoral crest relatively high, one-half the diameter of distal end of bone. 
The sternal crest after careful removal of the pectorals is very high and apparently with- 
out notch, but the greater part of the interpectoral septum is membranous. The phalanx 
of the second digit about as in Vespertilio. The metatarsi and first row of phalanges of 
toes equal. . 
Measurements.—Forearm, 36 mm.; foot and thumb of same length, viz., 8 mm.; fore- 
arm, 1.35 mm. 
BRACHYPHYLLINA. 
I propose to establish the Brachyphyllina to include the genera Brachyphylla, 
and Phyllonycteris,* forms which have hitherto been assigned separate groups in the Phyl- 
lostomidie, the first named to the Stenodermata and the second to the Glossophagina. 
Brachyphyllina. 
Leaf-nosed bats with tip of tongue retaining clump of papille extending across 
dorsum. In the Glossophagina the papille are arranged not only at the tip but the 
sides for great lengths. The minute first upper premolar wedged in between the 
canine and large second premolar; coronoid process acute, raised high above the level 
of the condyloid process. Mesopterygoid fossa deep, apex answers to the junction of the 
anterior and middle third of the zygoma. Nasal bones high, arched, defining a depres- 
sion between them and the maxilla. Sagitta entire with well-defined pretemporal crests. 
The glands of muzzle continuous behind nose leaf. Thumb large, one-fourth the length 
of the forearm, nearly. Auricle narrow, oval with pointed tip. Tragus coarsely serrate 
entire length of outer border. Upper lip hairy, without warts. Lower lp with shallow 
median groove, margined with large warts. Lips not fringed internally. 
BrAacHYPHYLLA. 
Upper central incisors very much larger than the laterals. Length of forearm, 65 
mm.; that of thumb, 16 mm., this being about one-fourth the length of the forearm as in 
Phyllonycteris. Grinding surfaces of molars with numerous large mammillations, cuspi- 
dation distinct. Angle of lower jaw quadrate, massive ; nostril entire, the wide outer 
margin and the side of the rudimental nose leaf continuous. Tragus entire on inner 
border. The tail rudimental, one-fourth the length of tibia, and concealed im the inter- 
femoral membrane. 
Dental formula: i. ¢— ce. +— prm. #— m. 3 = 20. 
* T have not studied Riinophylla, but the conclusions arrived at after reading the accounts of Peters and Dobson 
induce me to place the genus in the same alliance with genera just named. But in the absence of material I am com- 
pelled to confine my comparisons to Grachyphylla and Phyllonycteris.
