Fingers veiy slightly webbed. Vomerine teeth in two more or 

 less obhque series, each beginning/rom the front angle of the interior 

 nostiils. Skin of back smooth ; tympanum nearly as large as eye ; 

 in adult specimens the skin of the hinder -^axt of crown and of the 

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

 brownish spots, or with two curved narrow Hues, 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 vomeiine teeth arranged 

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

 between these forms, No other character — neither of the form the 

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

 of country — corresj)onds with these differences in the dentition,
