AUSTRALIAN SNAKES. 
79 
The geographical range of this species is very extensive; it inhabits 
almost every part of Australia, except the southern districts. The 
markings vary considerably in different individuals, hut in all, complete 
rings are formed, the black hands being generally as large again as the 
white ones. Examples occur in which the black marks narrow very much 
on the belly, and others which have the head-shields rather irregular; still 
it is difficult to find sufficient corresponding characters to warrant the 
establishment of a separate species. Since writing this, a very young 
Vermicella has been received from the Upper Burdekin, collected by Mr. 
Bainbird, for which we propose the specific name of lunulata, provided 
that older specimens, when discovered, will present the same markings. 
Our figures are somewhat enlarged.
