Hah. Central Queensland (Herbert-River district). 



Go-types in the Christiania Museum. 



The variability in the presence or absence of white rings round 

 the limbs of this species is a very remarkable characteristic, 

 and has been thought to be of specific value by Mr. De Vis, who 

 has separated the non-ringed form from the other under the name 

 of Ps. mongan. On a renewed examination of the typical specimens, 

 however, I must agree with Dr. CoUett in looking upon these rings 

 as of too little importance to distinguish animals otherwise so 

 precisely, identical.
