AUSTRALIAN SNAKES. 61 



eyes small, pupil roiuid. There is an indistinct small yellow spot behind 

 the upper part of the eye ; but this may be an accidental variety, as the 

 spots on the two sides are not equally defined. 



A single specimen in the Museum collection, probably from South 

 Australia. Capt. (now Sir George) Grey discovered the species on the 

 West Coast.

This species has been considered to be a variety of Hoplo- 

 cephalus gouldii ; this is not so, however, as the following description will 

 show : — 



Head depressed, scarcely distinct from trunk ; vertical five-sided, 

 with acute angle behind ; occipitals large, not much forked ; anterior 

 frontals triangular ; posterior frontals quadrangular, soinewhat larger 

 than the former. Six upper and six lower labial scales, smooth, rather 

 short, six-sided, lighter on the outer margin. 



Greyish brown above, yellowish white below ; the marks upon the 

 head vary in different individuals ; rostral, nasal, and anterior part of first 

 pair of frontals marked with black ; remaining portion of anterior frontals 

 and whole of posterior ones reddish, after which another black patch covers 

 the vertical, superciliaries and part of the occipitals; pupil subelliptical, 

 erect ; a third black spot covers the nape of the neck, about four scales 

 wide, but not reaching to the sides. In some of the specimens the second 

 black patch is continuous, leaving only the tips of the occipitals and the 

 scale between them reddish. 



Habitat, Port Lincoln, South Australia. Discovered by Mr. G. 



Masters.
