ON THE GLOSSOPHAGIN A. 207 
The alveolar process so slender that it cannot be measured. The parts as viewed 
from in front embrace the floor of the nasal chambers at the premaxillary part and permit 
the median foramen to be seen. The zygoma without a trace of ascending process. The 
posterior palatal margin near the root of zygoma spinose ; the posterior palatal notch with 
conspicuous spines. Pterygoid process almost reaching tympanic bone and extends 
beyond the oval foramen. Mastoid process aciculate. Mesopterygoid fossa with incon- 
spicuous yomerine spine.  Basioccipital depressions shallow. |The coronoid process 
scarcely raised above the level of the condyloid process. The deflected hamular angle 
projects in a marked degree beyond the condyloid. The lower border of the masseteric 
impression is produced conspicuously beyond the border of the ramus. Symphysis with 
large keel. One skull 21 mm. long; face 8 mm. long; brain case 15 mm. long. 
Upper Teeth_—The small central incisors separated by wide interval, and each tooth in 
close contact with the large lateral. The central incisor with ovoid crown scarcely wider 
than neck ; the lateral incisor projecting below the level of the central with crown wider 
than neck and conspicuously oblique outer border. The interval between lateral incisor 
and the canine no greater than in other genera. Canine with inner surface flat. First 
premolar one-half the size of the others; separated from the canine and the second pre- 
molar, but nearer the last-named tooth. The second and third premolar triangular, with 
large basal cingules. 
The W-pattern of the molars discernible. In one specimen the long, sloping proto- 
cone with suggestion of hypocone, recalling the parts as in Macrotus ; in the second the 
teeth were without hypocone. Canine with rudimental heel. First premolar separate 
from the canine and second premolar. Second premolar separate from the first and third ; 
third premolar separate from the second, but contiguous to the first molar. First molar 
with cingule of the protocone extended forward, scarcely deflected inward and overlap- 
ping third premolar; protocone and paracone approximate, united at base. 
Lower Teeth.—First lower premolar without anterior basal cusp, and is, therefore, 
much smaller than the other premolars. In the entire series of premolars the main cusp 
is twice as high as the height of the basal cusps. The first and second molars of 
the same plan with the foregoing, the third being slightly the smaller. 
The lower teeth with jaw are figured by Leche (/.¢., Taf. I, Fig. 8). The first pre- 
molar is represented as being exactly like others of the series. This character would 
prevent the Lonchoglossa of Leche’s identification being received under Lonchoglossa 
caudifera of this essay. ; 
Variations.—The above description is based on two specimens, which were subject 
to some variation. In one the pretemporal crests did not unite. In one the cusps of the 
teeth were much worn.
