scales much smaller than ventrals, feebly keeled. A dorso- 

 lateral crest on each side of the neck. A well-developed 

 dorsal crest, beginning on the neck and extending on the 

 anterior part of the tail, composed of closely-set compressed 

 spines. Body covered above with very strongly keeled scales, 

 largest and more strongly keeled on the middle of the back, 

 not intermixed with enlarged scales. The keels converge 

 towards the vertebral line. Ventral scales very distinctly 

 keeled. The hind limb stretched forwards reaches beyond 

 the orbit. Limbs with keeled scales. About 55 pores, ex- 

 tending along the whole length of the thighs^ scarcely inter- 

 rupted on the prffianal region. Caudal scales equal, keeled. 



Brown above, head and body with irregular dark spots 

 and lines. Four large dark spots on the middle of the ante- 

 rior part of the back. Tail uniform brown. Lighter beneath. 

 Lower surface of head with smaller black spots and a large 

 one in the middle line reaching from snout to the gular sac. 

 The anterior part of belly and the middle of chest black. 

 Lower surface of fore limbs black.

West Australia. A single specimen, collected by Dr. N. 

 Hoist (Dec. 1896). 



This species seems to find a systematic position between 

 A. cristatus, Gray (Cat. Liz. i. p. 383), and A. caudi- 

 cinctus, Gthr. (Cat. Liz. i. p. 384). To^. cristatus^ Gray, it 

 is allied by the dorsal crest and the keeled ventral scales, but 

 these characters are more developed in this new species. In 

 A. cristatus, Gray, the crest is composed of a few widely 

 separated spines, the ventral scales are smooth or very feebly 

 keeled. This species has the crest composed of many spines, 

 in contact loith each others the ventral scales distinctly keeled. 

 In these points it is well separated from A. caudicinctus, 

 which has a very small nuchal crest, a slight dorsal ridge, 

 and smooth ventral scales. — With A. caudicinctus, Gthr., it 

 agrees in having the dorsal scales not intermixed with 

 scattered enlarged scales, as in A. cristatus.
