Strebloceras cygnicollis, Hedley, Proc. Linn. Soc., New South 
Wales, 1904, part 1, p. 189, pl. vilii., figs. 12 to 14. Type locality: 
—Port Jackson. Pritchard and Gatliff, Proc. Roy. Soc., Victoria, 
1906, vol. xviii. (N.S.), part 2, p. 56, recorded for Victoria. 
Dredged in 55 fathoms north-west of Cape Borda, 4 alive, 
1 dead. 
The smooth glassy embryonic portion beyond the marked 
varix is not equally thin-walled throughout, but the spire and 
the proximal fifth are solid, and then the very thick walls 
gradually thin towards the varix.

pb= (p0Triphora tasmanica, Tenison-Woods. Var. lilacina, Verco 
var. aureovincta, Verco, 
This exquisitely pretty little shell was taken in perfect 
condition in 55 fathoms off Cape Borda. 
It has a golden band like 7. regina, Hedley, but in- 
stead of colouring the most anterior spiral of pearls, it orna- 
ments the smooth spiral plait in front of this, and so is found 
in the suture and on the base of the body-whorl. Its proto- 
conch is that of 7'. tasmanica, and has not the spicular form 
of 7. regina. It is very deeply-coloured purple, like the var. 
lilacina, Verco. One example, perfect, of eight’ whorls, was. 
taken.

FELZOR ovapostrema, n. sp. Pl. xxx., figs. 1 and 2 BOS 
Shell immature, of eight whorls, including the proto- 
conch of two whorls, the first nearly smooth with a round 
projecting apex, the second with two stout prominent keels, 
gradually becoming nodular. In the first spire-whorl arises. 
a faint third spiral, posterior to the others (whence the specific 
name), which continuously enlarges till it nearly equals them 
in size. They are crossed by axial lire, about fourteen in the 
last whorl, both axials and spirals being well marked, the 
latter%he stouter, and being tuberculate at their intersection. 
The peripheral spiral is prominent and subtuberculate, it is 
visible in the earlier sutures, but not in the later; two flat 
obsolete plaits curve round the base. Colour white. 
Dim.—Length, 3°1 mm.; breadth, 1°2 mm. The largest 
example, immature, is 5°2 mm. 
Locality. —Dredged in 55 fathoms off Cape Borda, type: 
with 7 others, some quite fresh, all immature; in Gulf St. 
Vincent, 1.
