a light anterior and lateral margin, and a cream colored spot 
near the sutural margin ; body white, with from 31 to 34 annular 
black cross-bands, which are much broader on the back than on 
the abdomen ; lower surface of the head with longitudinal dark 
streaks. 
Of the three specimens examined in the preparation of this 
description, two were obtained through the kindness of Mr. A. 
Zietz, of the South Australian Museum, Adelaide, who collected 
them in the neighbourhood of Port Augusta, S.A., and who 
further informs me by letter that he has since received specimens 
from Port Pirie, S.A. The third specimen was collected by 
Mr. A. J. Campbell, of Melbourne, in West Australia, and 
forwarded to the Institution for identification. As the Museum 
Library does not at present possess a copy of the letterpress of 
Jan’s I conog rap] hie generate des Ophidiens , I have taken this 
opportunity of describing in detail this very distinct species. The 
largest specimen examined measured nearly ten inches.

The length of the head is three and two-fifths the total length. 
The eyes are situated at an equal distance from the tip of the 
snout and the superior angle of the gill-opening, and their 
diameter is one-half of the length of the snout, and iour-sevenths 
of the interorbital space, which is slightly concave. Nasal organs 
} pierced in the lower half of a bifid papilla, with only one opening 
on each side. Dorsal profile broad. The distance between the tip 
of the snout and the origin of the dorsal fin is four-sevenths c>£ 
the total length : the snout is two-thirds of the distance between 
the posterior dorsal ray and the origin of the caudal fin, and is 
equal to the height of the caudal pedicle immediately behind the 
anal fin, which is situated entirely behind the dorsal :* the pectoral 
fins are short and rounded : the caudal, which is also rounded, is 
five-sevenths of the length of the head. The entire body and 
head, with the exception of the lips, armed with long blunt spines 
with a slightly nodular termination ; these spines materially 
* The origin of the anal fin is perpendicularly beneath a point behind 
the dorsal fin, equal to the base of that fin.
