ON THE GLOSSOPHAGIN®. 253 
tibia; the tip projects slightly beyond the interfemoral membrane ; wing membrane 
attached at a point midway on metatarsus. Nose leaf acuminate, sparsely hairy.  Inter- 
nareal pedicle with midrib ; below two warts at median line in the short lip; outer flange 
at the nostril broad, tumid and gland-bearing. The gland mass proper well defined, but 
not across the face back of the nose leaf. 
Tail two-thirds the length of the femur and appearing free above the interfemoral 
membrane. Vibrissee on muzzle very long. Fur everywhere silky. Above, tips dark 
brown, the remainder of hair lighter brown. Beneath, lighter in shade, light brown, 
unicolored. No. 399, Acad. Nat. Sci., is smaller than the specimen named. The 
length of forearm is 33 mm. (about 1/50), and shorter than that assigned Chernyc- 
teris minor Peters. ‘The calcaneum, however, is not as long as the foot. The central 
incisors are absent in the upper jaw. In other respects the specimen resembles C. mezi- 
cana. I do not identify this specimen with C. minor, but regard it as a variation of 
C. mexicana. 
The Skull.—Skull papyraceous ; the divisions of the cerebellum and cerebrum discern- 
ible through the periphery. Temporal ridge almost n7/, not forming union at any part of 
the sagitta. Fronto-maxillary inflation absent, but the inner wall of the orbit and the 
fronto-nasal depression unite to form a ridge which bears a foramen. Face vertex without 
median fronto-nasal pit, but in its place a flat surface which bears a median ridge. No 
groove indicating positions of the nasal bones, but the outlines are seen through the 
translucent periphery. The sides of the face uniformly convex. The upper border of the 
anterior nasal aperture incised. The lateral margins of the anterior nasal aperture 
scarcely produced; the groove between them and the eminence over the canine teeth rudi- 
mental. The simple infraorbital foramen over the first premolar tooth. 
Alveolar process in height one-thirty-first the width of the neck of the canine and 
one-thirteenth the vertical diameter of the anterior nasal aperture. Six inconspicuous 
ruge. Zygoma incomplete. The infraorbital foramen on same vertical line between the 
second and third premolars. Hard palate acutely arched in molar range. The posterior 
border near root of zygoma with slightly convex margin; oval foramen well in advance of 
the pterygoid free tip which reaches the tympanic bone. The tympanic bone not 
reaching the postglenoid process. The palatal bone extends to the anterior lacerated 
foramen before forming the large subacuminate notch. Pterygoid process convex out- 
ward, forming bulla-like recesses. The mesopterygoid fossa with a faint vomerine ridge 
which is continuous with the conspicuous basioccipital ridge. The coracoid process 
acute, deflected outward, the angle produced beyond the condyloid process, and con- 
tinuous with the depressed lower border of the masseteric impression. Symphysis with 
pronounced carination. Brain case, 16 mm, long; face, 14 mm. long; or the face almost 
as long as the brain case, ©
