1870.~] Indian and Malayan Amphibia and Reptilia. 175 



very long and slender, about two-fifths longer than the third ; thumb 

 and inner toe are very short. 



Brownish olive above, usually with two series of small black 

 dots along the middle ; sides with a black band above, commencing 

 at the rostral, either uniform, or sometimes provided with white 

 spots and margined above and below with an indistinct pale 

 streak, continuing as a grey band with undulating margins to 

 the tip of the tail ; the lower half of the sides is in young speci- 

 mens yellowish and spotted with black, as are likewise the upper and 

 lower labials and the sides of the neck ; in full grown specimens all 

 these parts are densely marbled with blackish grey, the spots having 

 become more or less confluent ; the rest of the lower parts uniform 

 whitish ; the tail is in old specimens sometimes spotted with black ; 

 the legs appear to be above always spotted or marbled with 

 the same colour. 



I found this species very common at Martaban near Moulmein, 

 but I scarcely observed a single specimen south of Moulmein, nor 

 does it appear to extend further south into Welesley Province, 

 Theobald says that it is very common in the forests of Pegu. My 

 largest specimen measures 6f inches, of which the tail is 4 inches ; it 

 is proportionately longer in young specimens than it is in old ones. 



The species is very closely allied to H. indica, Gr r a y, {JEumeces 

 indicus apud Gr ii n t h e r, 1. cit. p. 89, non Mocoa Sikimensis, B 1 y th), 

 and I have given a detailed description of the former simply for 

 the purpose of a close comparison of the two, for they may possi- 

 bly turn out to be identical, the only appreciable difference of 

 B 1 y t h species from that of Gr r a y, as recorded by G- ii n t h e r, 

 being the larger number of supraciliaries and of the transverse 

 series of scales between the front and hind limb. Are the latter 

 really in such a small number present in H. indica as noted by 

 Giinther? If not, the two could scarcely be specifically different, 

 and if the locality of the Oumingian specimen from Ningpo be 

 correct, the species would after all seem to possess a wide geogra^ 

 phical distribution. 



H. maculata also occurs at the Andamans, though it is rare there,
