822 A CONTRIBUTION TO THE IlEHPETOLOGY OP QUEENSLAND, 



NOTE ON HETEROPUS. 



Heterojms fuscus, Gr. In the light of the description of H. 

 fuscus now in our hands (B. M. C. Liz., 2nd ed. vol. iii. p. 283), 

 the writer has no difficulty in accepting the identification with it 

 of his H. niaculatus. The account of the variations in colouring 

 shown by the lizard might, however, have been amplified with 

 advantage. 



Heterojius rostralis, m., is by no means to be identified with 

 H rhomboidalis, Pet., a rather common lizard on the North Coast. 

 S. rostralis has the interparietal distinct. 



Seterojnis bicarinatus, Macl., ( = //. albertisii, Pet. and Dor.) is 

 not infrequent at Herberton. 



Heteropus peronii. Considered as a Lygosoma, this species 

 must lose the duplicate name peronii. R. lateralis, m., is quite 

 distinct. Myophila vivax placed in the same synonymy, is a 

 naked-eyed seine. IT. blackmanni, m., is fairly identifiable by the 

 description given 1. c. p. 286. We may call it therefore either Lygo- 

 soma blackmanni or Heteropus peronii, according to our judgment. 



The following key to the Queensland species may be useful : — 

 Palpebral disc not larger than the ear orifice. 

 Interparietal distinct. 



Dorsals tri-or quadricarinate, or nearly smooth. 



Toes cylindrical, with broad lamellae fuscus. 



Toes compressed with narrow lamellae rostralis. 



Dorsals bicarinate bicarinatus 



No interparietal rhomboidalis. 



Palpebral disc larger than the ear orifice. 



Dorsals sharply keeled 



Doi'sals bicarinate peronii. 



Dorsals tricarinate 



First supraocular longer than the second vertebralis. 

 First supraocular shorter than the second 



Scales in 28 rows lateralis. 



Scales in 32 rows jjectoralis. 



Dorsals smooth or feebly keeled 



Scales in 30 rows inundus 



Scales in 34 rows tetradactylus.
