It ranges alive from the shore (Henley Beach, “with a 
purple mucus,” A. Zietz), to 12 fathoms Porpoise Head, and 
92 fathoms Backstairs Passage; and dead in perfect condi- 
tion in 104 fathoms 35 miles 8.W. of Neptune Islands. ;

Vincent Gulf, S. Aust.; Tryon, Man. Conch ix., p. 69, pl. 14, f. 
39, 1887; habitat, New Caledonia. 
Tryon defines it as “‘very minutely spirally striated,” but 
Crosse says “the intervals between the ribs are smooth.” No 
fine spiral lines could be detected by me on the two shells in 
the British Museum, labelled “8. delicatula, Cr. and F., 8. 
Aust., G. F. Angas,” on the back of the tablet being “S. | 
Aust. and New Zealand. Type.”

_give S. consors, Crosse and Fischer, Journ. de Conch., 1864, 
p- 347; 1865, p. 43, pl. iii., f. 11, 12, as a synonym; but the 
type shell in the Brit. Mus. shows a well-marked peripheral 
keel, which none of our S. Australian S. jukesiana possesses.

On the tablet in the Brit. Mus. is “Swan River, Austra- 
lia, on the sands, unique, Dr. Collie, type.” Our shells are 
identical with this; but one measures 22 mm., 7.c., 6 mm. 
longer than the type. Porpoise Head, 12 fathoms, 2 recent, 
2 dead ; Backstairs Passage, 20 fathoms, 1 recent.

This species, misidentified, was listed in Handlist of Aq. 
Moll. of S. Aust., Adcock, 1893, as No. 195, 8. amperialis, Sby. 
It is very rare. The Levens Beach, Spencer Gulf (W. T. Bed- 
nall) ; St. Vincent Gulf (D. J. Adcock).
