~ AMPHIBIANS AND REPTILES. a 
first third in head. FEjyelids rather thin, ball of eye itself not 
much elevated. Mouth broad, gape straight, and when viewed 
below its profile more evenly convex than that of upper jaw. 
Lips hard and rather firm, upper with but a trifle of swelling on 
each side. A single series of nearly even small teeth around 
edge of each jaw. Palatine teeth in a transverse series, separated 
into a right and left patch, which is annectant at their approxti- 
mation at each end of parasphenoid series so as to form an 
abrupt rectangle. Tongue a nearly circular disk, free, supported 
on a slender pedicel like a mushroom. Internal nares minute, 
placed close in front of middle of each transverse patch of pala- 
tine teeth, and each giving off a well-defined narrow groove 
extending out to margin of jaw externally. Distance between 
internal nares a little greater than bony space between eyes. 
External nostrils not very high along edge of snout and a trifle 
further apart than bony interorbital space. Internasal space 
convex and interorbital space flattened. Occipital region slightly 
convex. Skin lustrous and perfectly smooth. No indications of 
glands secreting a milky juice but skin everywhere beset with 
closely-set shallow pits. A circle of pores around eye extending 
anterior to those on side of head to nostrils, and more crowded. 
Lower edge of mandible encircled by a single series of pores, and 
2 other nearly straight series start from point of chin and diverge 
backwards. Fore limb inserted near first seventh in body, 
reaches 14 of space to hind limb, and rather short. Digits 
feeble, rather depressed, with convex surfaces, elongately tri- 
angular, and tips rounded, though not disk-like. No webs, 
tubercles or keels to digits. Third finger longest, about 4 in 
rest of arm, first shortest, and. fourth a little shorter than third. 
Hind limb inserted nearer tip of tail than that of snout by space 
equal to about length of gape. Fourth toe longest or about 41% 
in rest of leg, first shortest, second and fifth subequal, and a 
little shorter than third. Vent close behind insertion of hind legs 
as a longitudinal slit. Color in alcohol brownish above and pale 
or dull creamy-brown below. Back mottled entirely with large 
‘well-defined slaty-dusky blotches or spots, some more or less 
confluent, though all larger and more conspicuous than else- 
where, In size they attain nearly that of eye-ball. On snout
