times the colour is a very deep, almost blackish-brown, with a

Carinaria australis, Quoy & Gaimard. waa 
Quoy & Gaimard, Voy. de l|’Astrolabe, Zool., vol. ii., 
page 394, Pl. xxix., figs. 9, 13, 1833. The type specimen was 
dredged between New Holland and New Zealand in January, 
1827. Mr. Hedley supplied me with the following quota- 
tion from Voy. de |’Astrolabe, Histoire du Voyage i1., 1830, 
page 27:—“January 2, 1827, the zoologists collected some 
living carinarias, the shells of which attained a length of eight 
to ten lines.” The next day the vessel was 130 leagues from 
Port Jackson, on the way to Cook’s Straits, New Zealand. 
Allowing about a hundred to a hundred and fifty miles for the 
day’s run, we can fix the locality of the haul of Carinarias at 
about 158° H. longitude and 40° §. latitude. My single 
specimen was taken in January, 1905, in 104 fathoms, in 
sandy ooze, 35 miles south-west of the Neptune Islands, be- 
low the entrance to Spencer Gulf, in E. longitude 135°40°, and 
8. latitude 35:25°. So its habitat is extended some 22 or 23 
degrees to the west. It measures 10 mm. in length and 3°75 
in width. Several characters can be added to those given by 
the authors. The transverse ridges spreading fan-like from 
the posterior part to the carina increase in number by inter- 
calation of secondary and tertiary ridges. The carina is un- 
dulated in its proximal part, where it springs from the shell, 
but its distal edge is straight, not corrugated, and only at the 
back part, where the distal border has been worn or broken 
away, is it actually undulated at the margin. The aperture 
is oval, and is about twice as wide towards the posterior part 
as at the anterior. From within a portion of the protoconch 
can be seen projecting through the posterior wall of the shell 
somewhat obliquely and slightly to the right of the middle 
line. The record of this shell adds not only a new species and 
a new genus to the South Australian list of marine molluscs, 
but a new order of Gasteropods ; the Nucleobranchiata. At> 
lanta, another genus of this order, is also represented by an 
undetermined species taken in the same haul.

This is a fairly common species. It has been dredged 
alive at 14 and 25 fathoms in Spencer Gulf, and dead at 15
