AMPHIBIANS AND REPTILES. 12% 
length of head and trunk, though processes not especially elevated. 
Head moderate, broad, well depressed above and below, though 
anteriorly a little convex. Snout broad, largely convex above, 
its length about half its width, and when viewed above with rather 
narrowly convex profile. Eye elongate, rather large, well ele- 
vated, and placed over 4/, length of gape or about first % in 
space between tip of snout and shoulder. Mouth large, gape 
straight and horizontal. Lips thin and upper overlapping edge 
of mandible all around when mouth is closed. Lower lip rather 
firm. When viewed below mouth rather elongately triangular, 
and rather broadly convex at symphysis so that protruding profile 
of upper jaw is seen as less convex. Symphysis of mandible with 
a slight fleshy projection fitting into a corresponding depression 
in front of upper jaw above, and on edge of lip along each side 
of process of mandible a slight indenture. Teeth in upper jaw 
fine, short, in a narrow band, better developed anteriorly, and 
more or less concealed. No mandibular teeth, edge firm. Vomer- 
ine teeth in 2 small closely approximated patches convergent pos- 
teriorly, and placed a trifle behind line between inner nares. 
Tongue large, ovoid, with bulge posterior, and posterior margin 
with a deep incision. Surface finely papillose. Sides and pos- 
terior part of tongue free. Internal nares placed a little further 
apart than outer. External nostrils conspicuous above on side 
of snout in front, much nearer its tip than eye, and internasal 
spacé a little greater than bony interorbital width. Internasal 
and interorbital spaces nearly evenly level. Loreal region slightly 
concave. Tympanum rounded, a little longer than deep, close 
behind and partly below level of eye, and its horizontal diameter 
about 34 of eye-socket horizontally. Skin smooth over most of 
body, back, especially sides from after tympani, and dorsal sur- 
faces of femoral and tibial regions more or less granular or papil- 
lose, though most coarsely so on costal region. No glandular 
folds on back. <A slight keel from below external nostril back 
till below tympanum. A groove, narrow and well defined, ex- 
tends from posterior margin of eye back over tympanum, and 
then down to posterior boundary of vocal vesicle. Vocal vesicles 
large and capable of considerable inflation. Fore limb inserted
