Head once and two-thirds as long as broad, slightly longer than the tibia; forehead concave ; frontal ridges distinct, divergent; upper head-scales rugose, not keeled ; scales on frontal ridges and supraorbital semicircles large, the latter in contact on the interorbital region; three large supraoculars, forming together a disk separated from the supraorbital semicircle by two series of small scales; occipital large, a little larger than the ear-opening, separated from the supraorbital semicircles by two series of small scales; cantlial scales four, loreal rows six ; six or seven upper labials to below centre of eye ; ear-opening large, vertically oval. Gular appendage very large, extending far back on the breast; gular scales smooth. Body compressed; no dorso-nuchal fold. Dorsal scales small, smooth or faintly keeled, irregular, juxtaposed ; lateral scales minute, granular; ventral scales larger than dorsals, smooth, juxtaposed. The adpressed hind limb reaches the eye; tibia as long as the distance between the end of the snout and the ear; digits moderately dilated; 20 lamellae under phalanges II and III of the fourth toe. Tail feebly compressed, not crested, once and three-fourths length of head and body. No enlarged postanal scales. Greyish above, with black wavy and vermicular lines; two parallel black lines on each side from shoulder to hip ; belly white ; gular appendage bright red. Total length....... 225 millim. Fore limb....... 37 millim.

A nolis l io g a ster . (Plate VI. fig. 2.) Head once and a half as long as broad, longer than the tibia ; forehead deeply concave ; frontal ridges strong, short, divergent; upper head-scales smooth or feebly keeled; scales of the frontal ridges and supraorbital semicircles large, the latter in contact on the inter orbital region or separated by one series of small scales ; three large, smooth or faintly keeled, transverse supraocular scales forming a single longitudinal series, in contact with the supraorbitals or separated from them by one series of small scales ; occipital larger than the ear-opening, separated from the supraorbitals by one or two series of scales ; canthus rostralis sharp ; canthal scales * For explanation of the Plates, see p 217. |
