AMPHIBIANS AND REPTILES. 113 
between tip of snout and shoulder, or about over first 34 of gape 
of mouth. Mouth large, and gape nearly horizontal. Lips thin, 
firm, and upper overlapping edge of mandible when mouth closes. 
Lower lip very firm, scarcely developed. Viewed below mouth 
broadly convex, slightly more so than upper profile of head, as 
snout and upper lip protrude a little. ‘Teeth obsoletely uniserial 
in upper jaw, and apparently absent from mandible. Vomerine 
teeth small, in 2 small patches a little convergent posteriorly be- 
tween internal nares, and patches but slightly separated. ‘Tongue 
thick, large, fleshy, surface finely papillose, and slightly notched 
along its posterior edge, at which region it is also free for about 
half its length. Internal nares placed equidistant to edge of bony 
interorbital width. External nostrils well within limits of bony 
interorbital space, and a little superior on front side of snout. 
Internasal and interorbital spaces more or less levelled, and me- 
dian depression very shallow. Loreal region slightly concave. 
Tympanum rounded, nearly circular, close behind eye above ric- 
tus. Skin warty, rather coarsely tubercular with finer granula- 
tions intermixed, except on loins, and anterior and posterior faces 
of thighs. Lower surface with granules distinct, and well-defined, 
though less conspicuous on throat, palms and neck. A prominent 
and distinct fold of skin across throat, and another across breast 
better developed. Fore limbs inserted about first third in head 
and trunk, rather short and stout, and reaching a little beyond 
groin, though not to end of trunk. Fingers 4, broad, depressed, 
dilated at tips into broad disks, and that on third finger nearly 
equal to tympanum in diameter. A slight web connects fingers 
at base. Third finger longest, about 224 in rest of arm, and 
others more or less subequal, with fourth a little shortest. Disk 
on inner finger smaller than others. Hind limb rather long and | 
slender, femoral and tibial regions of about equal length, and 
rest of limb about a third again as long. Toes well webbed, and 
with well-developed disks, those of first and second least devel- 
oped. Fourth toe longest, first shortest, second next in size and 
third and fourth about subequal. Vent superior. Color in alco- 
hol pale brownish, with slightly deeper gray-brown blotches on 
back indistinctly. Across element of each limb a pair of deeper
