ceding snout. The round gutter at the back of the aperture 
is very marked. The varices do not run continuously from 
spire to spire as in Ranella, but stand one-fourth of the cir- 
cumference behind that in the spire below. 
An identical specimen was sent to me some years ago as 
from Japan by Mr. Sowerby under the name 7'riton ranel- 
loides, Reeve.

Dredged in 101 fathoms 80 miles west of Eucla, 1 imma- 
ture, 50 mm. by 27 mm., with a conical protoconch of four 
sloping convex whorls, the minute extreme apex appears to be 
absent; colour of shell, light bluish-grey, covered with a thin 
epidermis, like coarse muslin, with a minute erect hair at each 
intersection. Aperture quite white. Also, a mature shell 
90 mm. by 43 mm., solid, and lighter in colour than those 
from Tasmania.

The species was founded on several examples collected on 
St. Francis Island thrown up among the rocks, but none of 
them were full grown, and all of them were more or less rolled 
and damaged. But on May 27, 1912, the Federal trawler 
‘“Endeavour”’ obtained a perfect specimen from a depth vary- 
ing from 77 to 105 fathoms, about 40 miles west of the 
meridian of Eucla. It was inhabited by a hermit crab. It 
has nine whorls. The protoconch, comprising one and a 
quarter turns, is blunt, slightly excentric and smooth. The 
suture ascends for about a sixth of the circumference on the 
last whorl, and forms with a curved callosity on the inner lip, 
a narrow gutter at the back of the aperture. 
The aperture is obliquely axially ovate, narrowed pos- 
teriorly to a gutter and anteriorly to a short, wide, oblique 
canal. The outer lip is thin, simple, uniformly convex, 
slightly reflected, smooth within. The inner lip is an expanded 
glaze on the body-whorl, thickened internally into a curved 
callus, extending slightly above the back of the aperture at 
the suture; anteriorly the labium is thick, detached from the 
base of the whorl, and carried forward over the very valid 
varix of the canal to form a false, well-marked umbilicus, 
and to join almost at a right angle with the left margin of the
