Turbo supragranosus. 



Trochus (Gihlula) supragranosus, Smith, Journal Linn. Society, 

 London, Zoology, Vol. XII, p. 558, pi. XXX, fig. 15. 



Hab. Barnard and Fitzroy Islands, North East Australia ; 

 Sue and Duugeness Islands, Torres Straits ; Makera Harbour, 

 San Christoval; also, Florida Island, Solomon Islands, found 

 under stones ; Percy Island No. II, North East Australia, brought 

 up in the dredge from 18 fathoms. 



Mr. Edgar A. Smith remarks that one of the chief peculiarities 

 of this species is that the spiral liras on the last whorl near the 

 middle run in pairs ; the lirations on the spire become granulose 

 as the apex is approached ; the brown or pinkish brown stripes 

 which flow downwards from the suture are interrupted somewhat 

 by the transverse sulci, and thus appear as oblong dots on the 

 lirsB. On the back of the body whorl, not far from the lip, is a 

 large brown or pinkish brown stain. Mr. Smith places it in the 

 family of Trochidce. I have examined the operculum and find it 

 to be calcareous, therefore place it in the family Turhinidce. In 

 1865, I found it very plentiful .at Florida Island ; a great number 

 of specimens were obtaind at Darnley Island, in Torres Straits, 

 (dead) at the depth of 25 to 30 fathoms ; a few also were obtained 

 at Palm Island, North East Australia, at 8 fathoms sandy mud 

 bottom, specimens lighter in colour. 



DRAWINGS BY AUSTRALIAN ABORIGINES.

Plates 15 and 16. 



The drawings on sheets of bark, which I have laid before the 

 Society this evening, were obtained from the natives on Essington 

 Island, on the north coast of Australia. The aborigines of the 

 Australian continent appear to have been in the habit of painting
