tuberclcs. irregulaiiy scattered ; ventral scales imbricate, smooth, 10 in 

 a line as long as the nose, the scales on tlie cliin granulär. Male with 

 a series of femoral pores, interrupted in the middle by a short interspace, 

 6 — 9 on each side, Tail very depressed and flattened, in one specinien 

 as l)road as the neck, in the other considerably narrower, tapering to 

 a tine point, and covered with smooth imbricate scales, arranged in 

 verticils round the tail and intermixed \Yith large, pointed nail-like 

 tul)ercles in six longitudinal lateral series, three on each side: the 

 tubercles in the outermost series are the largest, forming a serrated 

 «dge on each side of the tail ; the scales on the under surface of the 

 tail are larger than those on the upper; of the latter there are about 

 7 transverse rows in a verticil, of the former only 2 — 5: there are 

 no transversely enlarged median plates on the under surface of the 

 tail, the merlian inferior scales, however, being larger than the lateral 

 and regularly placed in pairs. 



Pale greyish brown above with live dark wavy transverse bands 

 on the back, two on the posterior part of the head, and 7 — 10 broad 

 dark crossbands on the tail ; the head marbled with black, a narrow 

 dark line from the nose tlirough the eye to the Shoulder; the under 

 surfaces uniform whitish, on the tail marbled with black. 



Two specimeiis, botli niales, 



Measurenients : Total length 115 and 100 mm; length of tail 

 60. 50 mm: head to ear-oiiening 14, 13mm; nose .6,2, 6 mm: diameter 

 of eye 3,5, 3,3 mm: width of head 11, 10 mm: fore limb 18, 17 mm; 

 bind limb about 25 mm: largest breadth of tail 10, 6,5 mm. 



The two specimens are very like each other, and there is no doubt 

 about their belonging to the same species. The larger si)ecimen, however, 

 has, as shown aV)ove, a considerably l)roader tail than the other: it 

 may be that this character varies with age. The larger specimen has 

 also somewhat larger granulös, especially on the nose, and only 6 femoral 

 pores on each side, instead of 9 in the^ smaller specimen. 



The new species. kindly revised by Dr. G. A. BoULExaER, for 

 which I heg to express my sincere gratitude, seems to me to come 

 rather near to H. granti, described by Boulenger from Socotra, 

 but differs from it by fewer lamellae under the toes, by the very much 

 depressed tail. and by the quite unlike scaling of the tail.
