Show 1867.] MR. G. F. ANGAS ON AUSTRALIAN MOLLUSCA, 189 It is very rare, the few specimens known having been obtained on the rocks at Long Bay. Length 2 inches. 17. TRITONIUM (CABESTANA) DOLIARIUM. Triton doliarius, Lam. Anim. sans Vert. vi. p. 641. T. africana, A. Ad. (Ichaboe). A South African species, of which a few examples, evidently con-specific, have been found along the coast of New South Wales. Length 1 inch 6 lines. 18. BURSA (APOLLON) LEUCOSTOMA. Ranella leucostoma, Lam. Anim. sans Vert. ix. p. 542. Triton leucostoma, Quoy et Gaim. Voy. de l'Astrolabe ; Reeve, Conch. Icon. Ranella, pl. 1. f. 4. This fine large Ranella, which has so much tbe appearance of a Triton, seems to be an aberrant form, partaking of the characters of both genera. It is pretty common amongst the crevices of the rocks at low water about Port Jackson, and the coast of New South Wales generally. It is also found in Tasmania, and, according to Dieffen-bach, in New Zealand. It varies in colour from dark chocolate with banded varices to a pale reddish fawn-colour, and is covered with a short olive-green epidermis. Length 3| inches. Fam. BUCCINIDJE. Subfam. NASSIN^E. 19. EBURNA (ZEMIRA) AUSTRALIS. Eburna australis, Sow. Conch. 111. f. 5 (not Cancellaria spirata, Lam.). This very interesting shell, which belongs to the subgenus Zemira of H. and A. Adams, has been confounded by many authors with the Cancellaria spirata of Lam. They are, however, very distinct shells. Z. australis appears never to have been found anywhere but in Port Jackson, where it is rare and an inhabitant of deep water. My specimens were dredged at a depth of 8 or 10 fathoms, inside the north Head. The outer lip has a small tooth near the fore part, and the columella is smooth and truncated at the base. Length 8 lines. 20. *CoMINELLA ADELAIDENSIS. Buccinum adelaidense, Crosse, Journ. de Conch. 1864, p. 276, pl. 11. f. 6. This is the only species of Cominella I have met with in Port Jackson. It is of a whitish colour, transversely ridged, with the whorls coronately plicate below the sutures. Middle Harbour. Length 1 inch 2 lines. |
