1870.] Indian and Malayan Amphibia and R&ptilia. 173 



Eostral large, obtuse in front, forming a narrow suture with the 

 pre-frontal, which is contracted on either side and posteriorly ; 

 posterior frontals form a very narrow suture ; vertical, rather small, 

 rectangular in front, and posteriorly reaching to about the middle 

 between the eyes ; seven supraciliaries, prominent and strongly 

 arched, but the supraciliary edge itself is formed by about ten smaller 

 scales ; occipital sub-quadrangular, narrowly truncate in front, with 

 concave front sides, broadest and angular below the middle, and 

 slightly emarginated posteriorly ; it is followed by several large 

 post-occipitals, some of the temporals being also enlarged ; one 

 narrow, elongated supra-nasal on each side ; nostril large, rounded ; 

 2-3 loreals and 4 ante-oculars, the two upper ones being smallest ; 

 8 upper labials, the sixth largest, situated below the eye, 8 narrow 

 lower labials,the shields adjoining them being considerably enlarged, 

 and the first chin shield is single and largest ; lower eyelid with a 

 large transparent disk ; ear rather spacious, rounded without any 

 perceptible spines or granules. Scales round the middle of the body 

 in 37 longitudinal series, and there are about 60 transverse rows of 

 scales between the fore and hind limb. The scales on the sides are 

 only a little smaller than those on the belly and on the back ; all are 

 smooth, but with the lens many of the dorsal scales are seen in 

 reflected light, very slightly longitudinally grooved. A series of 

 eight scarcely larger scales forms the preanal edge ; sub-caudals 

 conspicuously enlarged. 



Colour uniform, iridescent brown above, most of the scales with a 

 large pale spot, and an indistinct pale band running from the nape 

 on each side of the back and disappearing on the tail ; below 

 uniform yellowish white, leaden grey on the tail. 



The only specimen figured was captured by me in a small temple 

 on the little island Pulo Tickos, situated just to the north of Penang 

 island ; a few other specimens, I saw on the shore, but they escaped 

 in crab holes under the refuse thrown out by the sea. A very 

 similar, or the same species, I have also observed on one of the 

 small islands near Singapore, but was not successful in capturing it. 



The Penang specimen is 7 T 3 g- inches, the tail measuring 4, the 

 posterior half appears to have been once injured, as the sub- 

 caudal scales become rapidly much narrower, but occupying nearly 

 the whole width.
