AMPHIBIANS AND REPTILES. 67 
measured from eye-sockets, 5; width of mouth 17%; fore limb 
a little more than head, though not quite equal to its length when 
measured to posterior bifurcation of gular fold; hind limb 8 in 
entire length of body; head and trunk 1% in tail, latter measured 
from just after vent to tip. Body depressed both above and be- 
low, especially elongated and slender. In form more or less 
cylindrical, with rounded or convex edges. Trunk not swollen, 
rather slender. Costal grooves 14, counting 1 at axilla and an- 
other at groin. Posterior or inguinal really a bifurcation of 
thirteenth groove. Grooves absent from pelvic region, and only 
a few traces of obsolete ones near base of caudal along its sides. 
Scapular groove really a posterior bifurcation of gular fold, and 
in turn sending bifurcation to shoulder or axillary groove. Gular 
fold well developed and sloping somewhat forward on neck be- 
low. On back above a slight median groove from occiput to base 
of tail, and lateral or costal grooves widely separated from it on 
Long Tailed Salamander. Spelerpes longicauda (Green). 
each side by smooth convex area of back, which is not in any 
way keeled. Belly and lower surface also smooth, costal grooves 
in no way encroaching. ‘Tail very long, slender, ending in a long 
acuminate point, compressed, and both upper and lower edges 
convex, not keeled. In transverse section tail would be more or 
less entirely ellipsoid. Head large, broader than greatest width 
of body, depressed both above and below, and greatest width 
opposite posterior portions of eye, parotid region not swollen. 
In profile obtuse, and angle forming a little superior in depth of 
head. Snout broad, a little more than twice as broad as long, 
projecting much beyond closed mandible, and its edge evenly con- 
vex as viewed from above. Eye a little ellipsoid or elongated, 
not especially elevated, rather small and placed near first third
