Head large, its width less than twice the distance from the end 

 of the snuut to the orbit ; snout longer than in G. verticillatus, 

 measuring 1| or If the diameter of the orbit and considerably more 

 than the distance from the orbit to the ear-opening; forehead 

 concave ; ear-opening oval, oblique, its vertical diameter generally 

 less than half the diameter of the orbit. Body and limbs rather 

 more elongate than in G. verticillatus ; digits free. The scales on 

 the head and back similar to those of G. verticillatus, but smaller ; 

 upper labials 12 to 14, first entering the nostril ; lower labials 10 

 to 12, gradually decreasing in size; chin-shields 3 to 5 on each 

 side, smaller than the labials, the inner pair generally longer than 

 the mental. Back with 10 or 12 longitudinal series of mamilliform 

 tubercles. Throat covered with exceedingly small granules ; ven- 

 tral scales larger than in G. verticillatus. Praeanal pores 11 to 16 

 altogether. Tail like that of G. verticillatus, but the scales on the 

 upper surface much smaller, the annuli being composed of 10 or 11 

 transverse rows of scales ; the large scales on the lower surface of 

 the tail are much dilated transversely, forming generally two 

 symmetrical series. Brown or brownish grey above, marbled with 

 darker, ^ith or without transverse rows of A\hitish spots, — a 

 character of the young in this and the preceding species, but which 

 may hei'e persist throughout life ; sometimes a linear, A-shaped 

 dark brown mark on the head ; tail annulate with darker and 

 lighter rings; lower surfaces whitish, generally dotted or variegated 

 with greyish. 



From snout to vent 7g inches ; tail 7.

Head moderately large, oviform ; snout longer than distance 

 between eye and ear-opening, about ]| diameter of the orbit; 

 forehead concave ; ear-opening oval, oblique, its greatest diameter 

 one third that of the orbit. Body and limbs moderately elongate ; 

 digits feebly dilated for the genus, with a rudiment of web. Snout 

 covered with rather large granular scales, the rest of the head with 

 very small granules intermixed with scattered larger ones ; nostril 

 pierced between the rostral and first labial ; upper labials 10 or 11, 

 lower labials 9 or 10 ; mental subtriangular ; a large median pair 

 of chin-shields, about three times as long as broad, bordered by a
