NATURAL HISTORY OF VICTORIA. 



[^Reptiles. 



its black upper uicargin easily clistiuguislies this beautiftil little snake 

 from all others. It has been supposed hitherto to be peculiar to 

 Tasmania, but it certainly (like the H. superbus., also supposed not 

 to occiu' on the mainland) is a not uncommon species about Mel- 

 bourne. 



I subjoin particulars of four specimens to show the small range 

 of variations in the scales and plates. This species is too small to 

 produce any serious injury by its bite. 



The figured specimen is that from Yarra-bank, while the one fi-om 

 Bullarook Forest was remarkable for a more general rusty reddish 

 coloring. 



The head only has been figured of this species before.
