1 50 Description of new Species of Reptiles. 



small ; body swollen ; skin of the back minutely granular, of the 

 belly smooth ; legs rather short ; toes 4.5, short, warty beneath, 

 quite free; the hind wrist with a large, oblong, compressed, in- 

 ternal tubercle ; the base of the inner finger with a conical wart, 

 ending in a small acute bony process ; tongue large, entire be- 

 hind. 



This genus has many of the characters of Cystignathus, but differs 

 from it in being warty and swollen, and in having short toes like a 

 Toad. 



Heleioporus albo-punctatus. Lead-coloured (in spirits), with white 

 spots ; beneath dirty white, with some small white warts at the 

 angle of the mouth ; legs smooth. 



Inhab. Western Australia. 



Cystignaihus dorsalis. The palatine teeth in a single large straight 

 line, just behind the inner nostrils ; tongue large, slightly nicked 

 behind ; the tympanum nearly hid under the skin, gray-brown 

 (in spirits), marbled with dark irregular spots, with a while 

 streak down the middle of the forehead and front of the back ; 

 sides pure white, spotted and marbled with black, beneath white ; 

 toes elongate, slender, tapering ; back part of thighs brown, white 

 speckled. 



Inhab. Western Australia. J. Gould. 



This species is very distinct from C. Peronii and C. Georgiamis, the 

 two Australian species described by MM. Dumeril and Bibron. It 

 agrees with the former in the disposition of the palatine teeth. 



Elaps Gouldii, Gray. Pale yellowish ; the scales of the back small, 

 six-sided, with a dark anterior margin, giving the back a netted 

 appearance; top of the head and nape black, with a yellow spot 

 on the rostral scale on each side just before the eyes ; head small ; 

 the occipital plates large, elongate ; the nasal plate triangular ; 

 one moderate anterior, and two subequal posterior ocular shields ; 

 six upper and lower labial shields, the fourth under the eyes ; eyes 

 small, pupil round. 

 There is an indistinct small yellow spot behind the upper part of the 

 eye ; but this may be an accidental variety, as the spots on the two 

 sides are not equally defined. 

 Inhab. Western Australia. 



This species resembles Cala?naria Diadema, which is also found in 

 Western Australia ; but it is larger, and the head is larger in compa- 

 rison with the body, and in this species it is the base of the scales, 

 while in the latter it is the outer margin that is dark.
