Between 40 and 120 miles west of Eucla, about the 100- 
fathom line, 4 examples were taken. Two, which were mature, 
measured only 80 mm. in length by 32 mm. in breadth and 
71 mm. by 30 mm. One nearly mature, 65 mm. by 29 mm., 
and one immature, 53 mm. by 22mm. A specimen from Port 
Victor measures 105°2 mm. by 50 mm., and one from Victoria 
124 mm. by 59 mm.; so that the deep-sea examples are much 
smaller and proportionately narrower. But their colour is 
typical, though faint (all were dead shells). They all show 
the typical proximity and heaping up of three plaits, with a 
very small plait behind these, and a distinct anterior plait 
close to and almost forming the border of the canal, though 
this last was absent from the juvenile example. One of the 
mature individuals showed obsolete axial coste on the base 
of the body-whorl, just beyond the inner lip, so approxi- 
mating to var. kenyoniana, Brazier. Further east the trawler 
“Endeavour” had taken several examples of this variety, pro- 
bably to the east of Bass Straits, all dead. A mature micro- 
morph was 65 mm. long by 325 mm. broad, the largest was 
112 mm. long by 49 mm. broad. The coste are more numerous 
than in the type of the variety described by Brazier (19 to 20), 
54 being counted in the penultimate whorl. But their validity 
and their number vary in the examples examined. In the 
micromorph they are less crowded, and in another specimen 
they are almost absent from the body-whorl. The protoconch 
and ornament resemble those of the specific type. I have had 
one of these figured on pl. xiy., figs. 2, 3. 
Since writing the above Mrs. Agnes Kenyon has kindly 
lent me the type specimen of Brazier’s species for comparison. 
This can scarcely be said to have 19-20 obtuse ribs, as he 
describes it. On the body-whorl 44 axial coste can be 
counted, and none in the last inch from the aperture. These 
are rather sharp at their summits, but broad at their bases, 
and vary very greatly in their size and proximity. In the 
penultimate there are about 50, but they are so irregular 
in size and nearness that it is difficult to count them, and 
they scarcely can be called ribs, but are rather irregular axial 
costule. The figs. 2 and 3 on pl. xiv. are an almost exact 
reproduction of the type, though taken from an ‘‘Endeavour” 
specimen in my collection.
