Bight. Dredged in 6 fathoms, and in 15 fathoms off St. 
Francis Island in poor condition; in 20 fathoms, Gulf St. 
Vincent and Investigator Strait, few, mostly dead; in 25 
fathoms, Spencer Gulf, 1 moderate: in 40 fathoms off Beach- 
port, 7 perfect and 19 good: in 55 fathoms, Cape Borda, 
7 moderate; in 62 fathoms off Cape Borda, 1 poor: in 110 
fathoms off Beachport, 2 good, but somewhat decolourized. 
It is not a common shell in our waters or on our beaches. 
Angas, in Proc. Zool. Soc., Lond., 1865, p. 172, gave its 
station as ‘deep water,” Gulf St. Vincent. This would mean 
something less than 25 fathoms. It is found perfect as deep 
as 40 fathoms and moderately good up to 55 fathoms, but 
beyond that poor. 
Hedley says, /oc. cit.:—‘‘No specimens examined afford- 
ed an opportunity for describing the protoconch.” I may 
add, therefore, that it is elongate and pointed of 44 whorls, 
which are convex, and have near their middle two carine, 
very close together, the lower of which enlarges and forms 
the lower of the two pearl rows in the first spire-whorl; the 
upper carina rather later deflects rather abruptly upwards 
and forms the upper row. The protoconch is axially closely 
lirate. The shell when adult may vary from 81 mm. to 
41, and may when of equal length vary distinctly in obes- 
ity, and also in the roundness of the lower part of the body- 
whorl.

This shell is usually longer and narrower than the ave- 
rage typical shell, is less rounded in the body-whorl, and 
has the sutural furrow rather more distinct, but in all these 
respects both the type and the variety vary. It is not a dead 
and bleached shell, but is taken quite white in a perfectly 
fresh condition. But some few specimens are uniformly very 
faintly brown, some have only the base slightly brown, some 
are just tinted brown over a greater or smaller vertical ex- 
tent of the spire, or over the centre of the whorl for one or 
two turns, proving it probably only a variety. 
It is taken perfect on the beach at St. Francis Island 
and Scales Bay on the West Coast; in 6, 15 to 20, and 35 
fathoms off St. Francis Island, 14 fathoms off Ardrossan, 20 
fathoms Investigator Strait, 45 fathoms off the Neptunes, 
55 fathoms off Cape Borda, 40 and 110 fathoms off Cape 
Borda; while in poor condition it is found in 130 fathoms 
off Cape Jaffa, and in 150 fathoms off Beachport. My dredg- 
ings have yielded more good specimens of this variety, and 
to a greater depth, than of the typical Jf, angasi, Crs. and 
Fischer.
