136 Mr. N. Rosen on the Lizards in the 



Gtlir. (Cat. Liz. i. p. 384), except the coloration. Lighter 

 beneath. Tail dark, with narrow indistinct li<>;hter (white?) 

 rings. In the ' Catalogue of Lizards' A. caudicinctua^ Gtiir., 

 is described as having regular black rings, narrower than the 

 interspaces between them. 



37. Amphiholurus reticulatus^ Gray. 

 West Australia {K Hoist, 1896-97). 



Twenty-three specimens (all from West Australia) are 

 preserved in the collections. They vary very much, forming 

 a continuous series, from such as have no trace of a nuchal 

 crest to those in which it is distinct and rather well-developed. 

 In some specimens the ventral scales are feebly but distinctly 

 keeled. Tiie coloration also is very variable. In other 

 characters they agree with the description of A. reticulatus, 

 Gray. — I have not been able to separate them into varieties 

 or species, and I have therefore referred them all to A.reticu- 

 latus, Gray.
