Chorophilus verrucosus, Cope, Proc. Amer, Philos. Soc. xvii. 1877, 
p. 87. 
Tongue large and wide behind, faintly emarginate. Vomerine 
teeth in two groups near the line of the posterior border of the 
choanee. Head narrow and acuminate; snout projecting acutely 
beyond the labial margin; canthus rostralis distinct, but obtusely 
rounded ; tympanum one fourth the diameter of the orbit. The 
hind limb being carried forwards along the body, the tibio-tarsal 
articulation reaches between the eye and the nostril. Skin of dorsal 
region tubercular, smooth warts of large and small size being irre- 
gularly crowded over its entire surface; belly granulate. Colour 
above leaden, with three longitudinal rows of darker, light-edged 
spots, extending one on each side and one on the median line; 
they are each composed of aseries of spots joined end to end; femur 
and tibia cross-barred ; upper lip dark plumbeous, with a series of 
five white spots ; a similar spot below the tympanum; inferior sur-

Tongue oval, slightly nicked. Vomerine teeth in two small 
groups behind the level of the choane. Head longer than broad ; 
snout subacuminate, prominent, twice as long as the diameter of the 
eye ; latter very small; canthus rostralis rather indistinct ; inter- 
orbital space a little broader than the upper eyelid; tympanum 
nearly as large as the eye. Fingers and toes moderately slender, 
latter with a slight rudiment of web; first finger shorter than 
second ; an indistinct outer metatarsal tubercle. The hind limb 
being carried forwards along the body, the tibie-tarsal articulation 
reaches hardly the tympanum. Skin granulate above and beneath. 
Yellowish olive above, with five longitudinal dark bands—the 
median bifurcating on the sacral region, the outermost extending
