AMPHIBIANS AND REPTILES. LIZ 
cave. Tympanum rounded, close behind and partly below eye, 
and a trifle shorter than horizontal diameter of same. Skin per- 
fectly smooth over entire body. A number of rather large pa- 
pillz around vent, most numerous and large just below. From 
tip of snout on each side a glandular fleshy keel to eye, and em- 
bracing nostril in its course. From behind eye this keel larger 
and pale in color, and extends back to postinguinal region. In 
their courses these keels will be seen slightly concurrent with 
outer profile, as viewed above, and with their greatest divergence 
at ovoid bulge of same. Just along edge of upper lip a pale 
elevated glandular keel extends back till above axilla, and it 
begins on side of tip of snout. Vocal vesicles developed. Fore 
limb inserted about */; in length of head and trunk, compara- 
tively large and robust, and when appressed reaches beyond 1n- 
sertion of hind limb a trifle. Fingers 4, large, attenuate, not 
webbed, swollen towards bases and upper surfaces only towards 
latter convexly depressed a little. Third finger longest, 2% in 
rest of arm, and first finger subequal. Second finger shortest, 
and fourth but little longer. Large tubercle on base of hand dis- 
tinct, and tubercles distinct at articulations of outer 3 phalanges 
of second and fourth fingers, present only at articulation of sec- 
ond phalange of first finger, and second and third articulations 
of third finger. Hind limb very long, femoral region robust, and 
equals tibial. Space between tip of fourth toe and heel 114 in 
rest of hind limb measured to vent. Fourth toe longest, very 
slender, and measured to incision of longest web, 51% in rest of 
limb to vent. Web of hind limb extending on fourth toe all 
space except 2 terminal phalanges. ‘Tubercles at articulations 
of phalanges of fourth toe 4, 2 on fifth, 3 on third, 2 on second 
and 1 on first. Fifth toe perhaps a trifle longer than third, and 
others graduated down to first. Cuneate tubercle well developed 
at base of first toe. Vent superior. Color in alcohol dull drab- 
brown above, creamy-white below, hind limbs more deeply col- 
ored, and throat and belly whiter. Back with rather elongated 
black blotches, a little irregular, and also extending on sides. 
Upper surface of hind limbs marked with similar colored bars 
and spots, most numerous on upper femoral region. Fore limbs
