Three specimens of this snake were collected, all with thirty-eight rows of 
scales only (B.M.C. 41 to 45); in structure and colouration they agree fairly well 
with the description of the type, but differ somewhat in the shape of head-shields 
from the B.M.C. figure, and to a less extent from each other. 
The species is evidently a variable one. We have in our collection a specimen 
from Townsville, Q., also with thirty-eight rows of scales, which cannot in any way 
be distinguished from these.
