1865.] MOLLUSCAN FAUNA OF SOUTH AUSTRALIA. 161 
Fam. TRITONID. 
27. TRITON BARTHELEMYI. 
Triton barthelemyi, Bernardi, Journ. de Conch, 1857, p..55, pl. 1. 
Si; 
Station. Amongst rocks at low tides. 
Hab. Cape Northumberland ; Gipps Land, Victoria. 
This large species bears considerable affinity to 7’. spengleri, Lam., 
from New South Wales; they differ, however, in the form of the 
aperture, in the number and character of the transverse ribs, and in 
the shape and sculpture of the upper whorls. 
28. TRITON SUBDISTORTUS. 
Triton subdistortum, Lam. Anim. sans Vert. (Deshayes’s edit.) ix. 
p- 638. 
Station. Amongst rocks at extreme low tides. 
Hab. Port Elliot, South Australia. 
This species appears to range from King George’s Sound to Tas- 
mania. It is not found on the coast of New South Wales north of 
Cape Howe. 
29. *TRITON WATERHOUSEI. 
Triton waterhousei, Ad. & Ang. Proc. Zool. Soc. 1864, p. 35. 
Station. Dredged on an oyster-bank. 
Hab. Port Lincoln, and Encounter Bay. 
This shell differs from 7’, spengleri in the squamato-pilose epider- 
mis, in the broad flattened varix of the outer lip, and in the double 
lire of the whorls.

30. Triton (Simputum) auovyt. 
Triton quoyi, Reeve, Conch. Icon. pl. 19. f. 93. 
Station. From 1 to 3 fathoms, on sandy shores, amongst the 
Zostera, or grass-wrack, so common in the gulfs beyond tide-marks. 
Hab. St. Vincent’s and Spencer’s Gulfs. 
I have received a large variety of this species from Tasmania. 
Fam. Buccinip&. 
No typical form of Buccinum has, as yet, been found on the South- 
Australian coast. The species known all belong to the genus Comi- 
nella of Gray, included under the subfamily Nassine. 
31. CoMINELLA COSTATA. 
Buccinum costatum, Quoy et Gaim. Voy. de -l’Astrol. Zool. ii. 
p- 417, pl. 30. f. 17-20. 
Station. Crawling on the sands at low spring tides. 
Hab. St. Vincent’s and Spencer’s Gulfs. 
This shell, in a young state, is very variable in colour. B. acuti- 
nodosum, Reeve, a closely allied species to B. costatum, does not 
appear to me to belong to the South-Australian fauna ; it is probably 
from the west coast of New Holland.
