fathoms, 2 dead; Investigators Straits, 15 fathoms, 3 alive, 3

Syn.—T’. clathratus, Woods, according to Von. Martens (Zool. 
Rec., 152, 1875). 
Murex scalarinus, A. Adams, is identical or allied, according 
to Tryon. 
Hab.—Middleton Beach, very many (D. J. Adcock). Aldinga 
Beach (J. C. Verco). Dredged Spencer Gulf, deep water, many 
alive and dead (J. C. Verco). The Levens Beach, under stones, 
Tasmania (Miss Lodder). 
My dredged specimens are identical with some forwarded by 
Miss M. Lodder from Tasmania. Mr. Adcock’s, from Middle- 
ton, appear to be the same species, but have a blunter apex, and 
a shorter snout, probably because beach-worn; they are also 
slightly larger and stouter, perhaps because from a more exposed 
locality, and more manifest color bands. These bands are evi- 
dently variable in number ; some have three, one just below the 
suture, a second in the centre of the last whorl, a third below 
the periphery, and winding round the base. Some have only 
the lower two, others only the lowest, and some are destitute of 
bands.

Ref.—Proc. Roy. Soc. Tasmania, 1875, p. 136. 
Type specimen, Tasmania. 
Hab.—MacDonnell Bay (D. J. Adcock) ; Victoria. 
8. T. Flindersi, Ads. & Ang. (Purpura). 
Ref.—Proc. Zool. Soc., 1863, p. 421. 
Type from Yorke Peninsula, 8.A. 
The operculum is distinctly muricoid, and not purpuroid ; and 
Tryon is right in transferring it to Zrophon from Purpura. 
Woods suggests that 7. Llindersi, 7. littorinoides (Ten.-Woods), 
and 7’. propinqua (Ten.-Woods) may prove varieties only of the 
same species. The Malacological Section of the Roy. Soc. of S.A. 
are of opinion that the latter two are synonymous with Ricinwla 
Adelaidensis ; but 7’. Flindersi, is a distinct species. | 
Hab.—Along the whole coast of South Australia, on rocks 
from high to low tides
