78 REPTILES. 



the glandular fold ; sides black-spotted ; beneath yellowish, throat 

 and chest finely dotted -with black. In the specimen from Madi'as, 

 the lateral dorsal bands are divided into rounded spots, and the 

 membrane between the fingers and toes is broader, but the tympanum 

 is as small as in the Ceylonese specimens. Length of body 2i" (adidt 

 female) ; length of hinder extremity 3i" ; length of front extre- 

 mity If".

Fingers very slightly webbed. Vomerine teeth in two more or 

 less oblique series, each beginning/rowi the front angle of the interior 

 nostrils. Skin of back smooth ; tympanmn nearly as large as eye ; 

 in adult specimens the skin of the hinder part of cro"mi and of the 

 forehead adherent to the skull, and nigose. Back with more or less 

 brownish spots, or with two cvu-ved narrow Hnes, forming an X- 

 shaped figure, and with a blackish stripe between the eyes ; never 

 with parallel bands. 



The direction of the series of vomerine teeth is liable to great 

 variation. There are specimens in the British Museum Collection 

 exhibiting two very convergent series, which, prolonged, would form 

 nearly a right angle ; others exhibit the vomerine teeth arranged 

 nearly in a straight line ; most of our specimens are intermediate 

 between these foims. No other character — neither of the form the 

 head, nor of the extremities, nor the coloration, nor the difference 

 of country — corresponds with these differences in the dentition.
