AMPHIBIANS AND REPTILES. 81 
overlapped by posterior part of upper. No distinct lower lip 
or groove. No gular groove or postrictal grooves. Parotid 
region not swollen. A series of small teeth in jaws. Vomerine 
or palatine teeth as a double series longitudinally, converging 
anteriorly, and joining after running close together between 
internal nares. In size these teeth minute like those in jaws. 
Tongue small, slightly free along sides, but not at posterior and 
anterior ends, and surface finely papillose. Internal nares about 
as far apart as bony interorbital space, and each with an outer 
groove towards edge of jaw. Exterior nostrils perhaps a trifle 
closer together than interior nares, and rather high on each side 
of snout in front. Internasal space convex and _interorbital 
largely flattened or level. On top of head 2 ridges enclosing a 
long lenticular open groove closed in front on muzzle and rather 
open behind at occiput. On each side of these ridges a shallow 
groove. Loreal region slightly concave. Canthus rostralis dis- 
tinct. Skin roughened with numerous semitransparent horny 
points on upper surface of body, and lower surface smooth. On 
side of head behind eye a series backwards of 4 pits. First 
near eye and last in position of first branchial fissure. In form 
pits shortly linear and curved as if made by an instrument with 
a. short curved edge. Distances between equal, or about same 
as eye-diameter, though first much closer to eye than its own 
length. Fore limb inserted about first ?/,, in body, and when 
pressed back reaches 34 of space to hind limb. Digits narrowly 
triangular, pointed, not swollen at tips, depressed, and with very 
slight membrane between toes. Third finger longest, 3 in rest 
of arm, first shortest, and fourth shorter than second. Hind limb 
inserted first 3/, in body, robust, and when pressed back reaches 
% to tip of tail. Third toe longest, fourth but little shorter than 
third, second shorter than third, first shortest, and fifth but little 
longer than first. Vent asa callosity directly after hind legs, and 
region about it swollen. Color in alcohol rich pale brown above, 
paler or light on lower surface, this latter also including some 
of limbs. Back, tail and limbs above finely though rather sparsely 
dotted with jet-black. A series of about 3 or 4 spots down 
side of back, with an annectant small whitish or yellowish dot
