Mr. Gray on new Reptiles from Australia. 91 



Heleioporus, Gray. Fam. Ranidae. 



Head short, swollen ; eyes large, convex ; palatine teeth in a 

 straight interrupted ridge between the two internal nostrils ; 

 teeth very 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, internal tubercle ; the base of the inner 

 finger with a conical wart, ending in a small acute bony pro- 

 cess ; tongue large, entire behind. 

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



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



Toad. 



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

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

 angle of the mouth ; legs smooth. 



I nhab. Western Australia. 



Ct/stignathus dorsalis. The palatine teeth in a single large straight 

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

 behind ; the tympanum nearly liid under the skin, grav-brown 

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

 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. Georgianus, 

 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 i:)lates large, elongate ; the nasal plate tri- 

 angular ; 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 Calamaria 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.
