RECORDS OF IV. A. MUSEUM. 
I have also found the same structure in E. striolata and E. whitei. 
A knife passed between the fleshy lobes, however, shows the true 
condition of the bones. 
Localities. — Eight specimens are before me, six adults and 
two young. The Type, together with three other specimens, was 
presented to the Trustees of the Australian Museum by Mr. W. D. 
Campbell, who collected them at Perth. There are also three other 
specimens collected by the same gentleman at Boulder. A single 
specimen, figured on PI. XXVII, Fig. 2, and Text Fig. 4, is in the 
Collection forwarded by Mr. Woodward, but is unfortunately with- 
out data. 
Type : — In the Australian Museum, Sydney. Reg. No. R.

Head small, sub-cuneiform. Snout rounded, acutely produced 
in profile, three to four times as long as the obital diameter, with a 
slightly projecting labial ridge. Eye small ; the lower eyelid with 
a transparent disc. Ear visible, minute, but generally covered 
with scales. Rostral twice as broad as high, highest in the mid- 
line; forming an arcuate suture with each nasal. Nostril pierced 
in the centre of a large swollen nasal which forms a moderate 
suture with its fellow. Fronto-nasal once and one-quarter to once 
and three-quarters as broad as long, forming a broad, curved suture 
with the frontal. Praefrontals small and widely separated ; some- 
times united with the posterior loreal and in contact with the 
second and third, or the third upper labial. Frontal large, much 
broader than the supraocular region ; a little longer than broad ; 
almost as long as its distance from the end of the snout ; in contact 
with the first supraocular. Supraoculars two, first much the 
larger. Three or four supraciliaries, the first one sometimes very 
long. Upper eyelid represented by a row of very small inbricate 
scales between the supraciliaries and the orbit. A group of small, 
irregular prae- and postocular scales. Frontoparietals separated 
by the interparietal ; about as large as the first supraocular, larger
