10. GYMNODAOTl'LTJS. 37 



Head rather large, oviform ; snout longer than the diameter of 

 the orbit or the distance between the eye and the ear-opening ; fore- 

 head and loreal region concave ; ear-opening suboval, vertical, about 

 one third the diameter of the e3'e. Body moderately elongate, de- 

 pressed. Limbs rather long ; digits moderately elongate, cylin- 

 drical in the basal, compressed in the distal phalanges ; the plates 

 under the basal phalanx very small, little larger than the surround- 

 ing tubercles. TIead covered with convex granules, largest on the 

 snout and temples ; rostral quadrangular, not quite twice as broad 

 as high, with median cleft above ; nostril pierced between the 

 rostral, the first labial, and three nasals ; nine to eleven upper, and 

 as many lower labials ; mental triangular or pentagonal ; a pair of 

 large chin-shields forming a long suture behind the point of the 

 mental, in contact externally and posteriorly with two smaller 

 pairs. Body covered above with large juxtaposed subequal tubercles 

 arranged in more or less regular transverse series ; these tubercles 

 flat or very slightly keeled, generally with a small raised point in 

 the centre. Abdominal scales round, smooth, subimbricate, much 

 smaller than dorsals. Males with enlarged prseanal and femoral 

 scales, but without pores. Tail cylindrical, tapering, covered with 

 uniform smooth scales arranged in rings. Eeddish brown above, 

 with narrow white, black-edged cross bars ; the first semicircular, 

 extending from one eye to the other across the nape ; a second on 

 scapular region, two on the body, and a fifth on sacrum ; similar 

 bands forming annuli round the tail ; lower surfaces whitish.

18. Gymmodactylus albofasciatus. (Plate IV. fig. 3.) 



This species resembles G. deccanensis strikingly in size, pro- 

 portions, and colour, but the following characters will at once 

 distinguish it. The dorsal pholidosis is not composed of uniform 

 large tubercles, but of intermixed smaller and larger tubercles, the 

 latter being mostly feebly keeled ; the small scales on the limbs 

 and upper part of the tail intermixed with larger keeled tubercles. 

 The ventral scales are larger, tubercular, and feebly keeled. No 

 chin-shields behind the median pair. The tuberciilar plates under 

 the basal phalanx of all the digits much more developed. The 

 ground colour of the upper parts is darker than in our specimens of 

 G. deccanensis, chestnut-brown.
