1Q4 • CYSTIGNATHUS ORNATUS. 



small, very dark coloured, and placed in a dark vitta, or blotch, which extends 

 from behind the orbit to within a short distance of the shoulder. 



The body is short, of a delicate dove-colour above, with two or more oblong 

 spots of dark brown, margined with yellow, on each side of the vertebral line; 

 below these, and on each flank, are three smaller spots, likewise margined with 

 bright yellow, the anterior one being the largest; these, with a smaller one above 

 the vent, form a triangle on each flank; several bright yellow spots, also disposed 

 in a triangular form, with the apices directed forwards, are concealed by the 

 thighs. The inferior surface of this animal is silver-white, and except on the 

 throat, every where granulated; about the throat are a few indistinct points of 

 black; the anterior and middle parts of the abdomen are white, with a slight 

 tinge; the posterior third approaches to flesh-colour. 



The anterior extremities are short, dove-coloured above, with a few distinct 

 dark bands placed transversely on the fore-arm, and a black spot at the elbow; a 

 black line runs from the inferior and upper part of the shoulder towards the lower 

 jaw; the fingers are four in number, distinct, nearly equal, and the thumb seems 

 less inclined to turn backwards than usual. The posterior extremities are also 

 rather short, dove-coloured above, with transverse bands of dark brown: on the 

 anterior part of the thigh are several small yellow spots; on the posterior surface 

 these spots are so numerous and so closely approximated, as to resemble at first 

 view a yellow waving line. The whole under surface of the thighs is flesh- 

 coloured and granulated; the inferior surface of the legs is also flesh-coloured, 

 with a few yellow dots; the toes are five in number, not palmated, the two outer 

 ones only are united at the base. 



Dimensions. Length of body from the snout to the vent, 1:1- inches; of the 

 thighs, 5 an inch; of the leg, -^ an inch; of the tarsus and toes, nearly i of an inch.
