DESCRIPTION OF A NEW SPECIES OF SHARK. 
By Arex. Morton. 
During the month I had brought to the Museum a 
peculiar-looking fish, having been found washed up on the 
beach at Bruny Island. On examination it proved to be a 
species of Centrina; at first I was inclined to believe it was 
C. salviani, but on closer examination it seemed to differ? A 
specimen of C. salviant having been found off the coast of 
New Zealand some few years back, I had a photo. of the 
Tasmanian specimen sent to Professor Hutton, F.R.S., 
Curator Canterbury Museum, Christchurch. Professor 
Hutton wrote, stating that, judging from the photo., he was 
inclined to think that the Tasmanian Centrina differed from 
the one in New Zealand, which he considered was Centrina 
salviant. Before finally deciding on making a new species, 
Mr. Ogilby, the able Ichthiologist of the Australian Museum, 
kindly undertook to compare the Tasmanian shark with the 
C. salviant in the Sydney Museum. After a careful exami- 
nation, Mr. Ogilby wrote, saying “that the enormous height 
of the dorsal fins, and their contiguity, the one to the other, 
separates this species at a glance from C. salviani; the scales 
also differ considerably.” I am very much indebted to Mr. 
Ogilby for his kindness in examining and furnishing me 
with the description. I propose giving it the specific name 
of bruniensis. 
CENTRINA.—Hach dorsal fin witha strong spine. Trunk 
rather elevated, trihedral, with a fold of the skin running along 
each side of the belly. Teeth of the lower jaw erect ; triangular, 
finely serrated ; those of the upper slender, conical, forming 
a group in front of the jaw. Spiracles wide, behind the eye. 
Two species, Centrina saiviani from the Mediterranean and 
neighbouring parts of the Atlantic and New Zealand. C. 
bruniensis, Tasmanian coast. 
Centrina bruniensis, Morton. 
Body oblong, with the back and sides rounded, and the 
belly flattened. Head small and strongly depressed, its 
breadth equal to the distance between the tip of the snout 
and the spiracle; snout short and obtuse, the distance be- 
tween its tip and the nearest point of the mouth less than 
that between the same and the anterior margin of the eye. 
Nostrils equidistant from the eye and the extremity of the 
snout. Hye large, with a strong bony supraorbital ridge,
