Triphoris festivus, A. Adams, Proc. Zool. Soc., London, 1851, 
p. 278. Type locality—Port Lincoln (Mus. Cuming). Angas,

Triforis festiva, A. Adams, Tate and May, Proc. Linn. Soc., 
New South Wales, 1901, vol. xxvi., part 3, p. 387, Tasmania. 
Dredged in 40 fathoms off Beachport, 1 good, albino; 
in 6 fathoms off St. Francis Island, 3 poor. This is a lit- 
toral form. Taken on the beach Yankalilla, Gulf St. Vin- 
cent, Spencer Gulf, many good; and at Scales and Smoky 
Bays, and St. Francis Island in the Australian Bight, a few 
good. 
The type was probably an immature shell, which would 
have a flat base: when mature the species has a rounded base 
with two simple spirals, besides the supra-sutural peripheral 
band. It has a four-whorled, brown, acutely-conical proto- 
conch, the first turn of which is smooth, the others unicarin- 
ate with axial bars. The shell when apex and base are per- 
fect may be 3°5 mm. long and 13 mm. broad, or 64 mm. 
long and 2:1 mm. broad. In the larger forms a threadlet 
arises in the later whorls between the two spiral pearl rows 
and becomes a third smaller row.

Dredged in Gulf St. Vincent, 11 poor; 14 fathoms, Ard- 
rossan, 1 good; 55 fathoms, Cape Borda, 3 poor: 90 fath- 
oms, Cape Jaffa, 2 perfect; 110 fathoms, Beachport, 2 poor. 
Taken on St. Francis Island beach, 2 poor. 
This seems to be a deeper-water form than 7. festiva. 
The protoconch may be brown instead of white as in the type.

Dredged in 9 fathoms off Edithburgh, 3 good; in Gulf 
St. Vincent, depth unrecorded, 14 good; in 55 fathoms off 
Cape Borda, | poor; in 110 fathoms off Beachport, 1 poor. 
Taken on St. Francis Island beach, 22 good. 
Mr. Hedley gives the length of his type as 67 mm., but 
some of my specimens reach 9°2 mm.
