254 ON THE GLOSSOPHAGINA. 
The Teeth—Wide interval between upper incisors. The central as described by 
Dobson, is smaller than the lateral. But in two specimens examined by me the centrals 
were larger than the laterals. Both teeth are inconspicuous and scarcely raised above 
the gum line. The palatal surface of the slender canine flat. Of the two premolars 
present, the first possesses both anterior and posterior cingules and without increase of 
width back of the cusp. The second is without posterior cingule, but is widened 
back of the cusp. The first molar with paracone extending the entire length of 
the tooth, but sloping from before backward. Protocone and’ mesocone without buccal 
fluting or palatal ridges. The second molar as the first, but the protocone ends at the 
beginning of the mesocone. The third molar as the second much smaller and all parts 
rudimental. 
The lower incisors deciduous. The slender canine with rudimental lingual cingule 
which does not extend beyond the level of the lateral incisor. The first premolar close 
to canine with cingule subequal to the cusp. The second and third premolars with cusp 
much larger than the prominent cingules. The first molar with protocone and paracone 
almost coalesced ; the protocone well advanced. The posterior border of the tooth is 
furnished with a prominent cingule apparently developed from the hypocone. The first 
molar is separate from the third premolar and the second and third from one another. 
Chernycteris exhibits vertical muscle fibres in the endopatagium, the nerve markings 
of the interdigital spaces and the shapes of the terminal cartilage of the fourth digit in 
a manner quite the same as in G'lossophaga, though the structure last named is less spatu- 
late than in that genus. 
Measurements.—The first phalanx of the first digit shorter than the metacarpal; no 
phalanx is present in the second digit. The metatarsi and the first row of phalanges 
equal. 
Tongue attached to floor of mouth at the level of the space between the second and 
the third molars, or 12 mm. from the symphysis. Penis not pendulous. 
ANURA. 
Interfemoral membrane hairy ; tail absent; wing membrane attached to midtarsus ; 
calcar absent ; no phalanx to second digit; two warts on upper lip; groove in lower lip 
wide with many warts. First premolar large remote from canine. 
Dental formula: i. + — ¢. + — prm. 3 — m. 3 = 22. 
Resemblance to Lonchoglossa very close. The general appearance the same even to 
the shape of the terminal cartilages of the phalanges. Skull and number of the teeth 
the same. But it is held that the tail, calear and phalanx to the second digit all being 
absent, separate Anura from the genus just named,
