REPORT OF NATIONAL MUSEUM, 1898. 



head is poiuted and depressed; the height scarcely two-thirds the 

 width, which is rather more than two-thirds the head to the ear. The 

 tibial joint is very short; all the limbs unusually feeble; the fore legs 

 extended forward do not reach to the eye, while in G. muUicarinatus it 

 reaches to the nostrils. 



The upper parts are of a light yellowish olive; the back with about 

 ten transverse broad bars covering two or three rows of scales; the 

 tail with about twenty-nine or thirty of the same. These are of a darker, 

 more reddish olive than the ground color, suffused with brownish black 

 behind, less conspicuously in front and the interval spotted with dark 

 brown. They are margined posteriorly (on the edges of scales) with 

 clayey white. Several of those along the middle of the back are 

 broken above and the branches displaced or alternating. On the sides 

 the posterior black border of the dorsal bars with their whitish edging 

 is continued down to the fold on a single scale. There is almost nothing 

 of this, however, on the side of the tail, except a slight shade of the 

 lighter portion. The sides of the same are marked alternately with seven 

 or eight olive and white spots, the former edged before and behind with 

 black. The plates of the head above are blotched with dark brown. 

 There is no trace of a dusky wash along the sides. The under parts 

 are olivaceons white, each scale, except along the middle of chin and 

 throat, with a black spot. 



Dr. Boulenger identifies this species with the G. {Elgaria) JdngiiGYAy 

 ( G. multifasciatus of Dum;.a'il and Bibron ). He, however, describes that 

 species' as having six or eight median dorsal series of scales, keeled, 

 which is not the case with the G. nohilis.
