J. yminanensis differs from J. variegata in the larger size of its scales generally, 

 a character which is especially discernible in the scales on *the throat. It is also 

 distinguished from that species by its proportionally shorter toes, and from J. 

 swinhonis by its much shorter legs {see table), to which, however, it approaches 

 in the large character of its scales. In J. variegata the sublingual scales are 

 nearly smooth, while in this species they are strongly keeled. 



The small J. planidorsata is distinguished by the numerous enlarged spiny 

 scales on the side of the head, and by the presence of from six to seven v- shaped 

 enlarged spiny scales, crossing the back from the upper portion of the side and 

 connected together at their free ends by a more or less interrupted longitudinal line 

 of enlarged scales. The first transverse line occurs on the nape, but the last is 

 reduced to a large spiny scale. The scales of the dorsal transverse bands are in a 

 single row. The scales on the middle of the body are smaller than those on the 

 dorsal surface and not so spiny. The planidorsate character is due to the trans- 

 verse and longitudinal lines of enlarged scales. I was at first^ incHned to regard 

 J. planidorsata as the young of J, variegata, but the foregoing description of its 

 characters, which is drawn up from the type, conclusively proves that the two 

 species are distinct, and that the late Dr. Stoliczka,^ was correct in questioning 

 the accuracy of my first determination. 



J. nigrilahris, Peters, from Borneo is a nearly allied species to J. planidorsata, 

 but devoid of the transverse bands of enlarged scales, but with the same form of 

 crest and the same hirsute appearance. 



Since I expressed the opinion some years ago that the J. microlepis of Jerdon 

 was probably the female of J, variegata, Gray, I have examined not only the 

 type in the British Museum, but have myself procured the species alive in the 

 Botanical Gardens, Calcutta, where it may have been introduced from Darjeeling 

 or elsewhere, either in the q^^, or alive in the cases of orchids and other plants that 

 are yearly received at these Gardens. The Calcutta specimen I have compared with 

 the type of T. microlepis, with which it perfectly agrees. 



I was for some time under the impression that this lizard from Calcutta might 

 prove to be the Otocryptis {Ftyctolcemus) gularis, Peters^ which was purchased as 

 coming from Calcutta. I therefore forwarded the Calcutta specimen to Professor 

 Peters, who kindly compared it with O. gularis, and pronounced it distinct, remark- 

 ing that O. gularis has no gular fold, but on each side three arched furrows 

 just before that place where J. microlepis has the gular fold, and that the latter 

 is nearly related to J. nigrilabris, Peters, from Borneo, yet distinct.
