This species, first discovered in Taiti, is mentioned by M. Bavay 

 as being found in New Caledonia ; and I entertain little doubt as to 

 the correctness of the identification. The following characters are 

 taken from three specimens in the British Museum (South-Sea 

 Islands, Philippines, Agam) which agree in every point with Bibron's 

 original description : — 



Head much longer than broad ; snout obtusely pointed, longer 

 than the distance between the eye and the ear-opening, once and 

 two thirds the diameter of the orbit ; forehead slightly concave ; ear- 

 opening small, rounded. Body and limbs moderate, depressed. 

 Digits free, or with a very slight trace of web, moderately dilated. 

 A slight but distinct fold of the skin along the flanks, and another 

 bordering the hind limb posteriorly. Upper surfaces and throat 

 covered with minute granular scales, a little larger on the snout ; 

 abdominal scales moderate, imbricate. Nostril pierced between the 

 rostral and three small nasals ; twelve upper and nine or ten lower 

 labials ; mental large, triangular, in contact posteriorly with a pair 

 of pentagonal chin-shields, followed by a second smaller pair ; the 

 anterior pair of chin-shields in contact with the first infralabial and 

 with its fellow mesially ; the posterior pair separated from each other 

 and from the labials. Tail elongate, depressed, narrower than the 

 body, with sharp denticulated lateral edge ; the scales on the upper 

 surface very small, equal ; those on the lower surface larger, imbri- 

 cate, with a median series of large, transversely dilated plates. 

 Brownish-grey above, uniform or with small indistinct darker spots ; 

 lower surfaces uniform whitish.
