C. allporti Tenison-Woods 1875 ( Zizyphinus ) (~ Trochus 
tinctus Watson). PL 1, fig. 1. “Allport’s Calliostoma/’ Tumid- 
ly conical, imperforate, rather solid; light translucent buff colour; 
dotted both on the spiral and basal cinguli with minute light 
chestnut spots; whorls about six, protoconch acute; adult whorls 
encircled by granular lirae, six on the penultimate and upper 
surface of last whorl, the beads distinct, rounded; base with 
about ten scarcely granulose concentric lirae; suture canaliculate; 
last whorl rounded at the periphery, slightly convex beneath; 
mouth obliquely quadrate, nacreous within; outer lip dir ate within; 
bidentate below; inner lip simple. Height 11, diam. 9 mm. 
Rare, on shore, Guichen Bay; dredged, Beachpoct, Cape Wiles, 
Royston Head, Backstairs Passage, 17-200 fathoms. (Type loc- 
ality — Islands in Bass Straits). A translucent, small, tumid 
shell, in habit much resembling a Thalotia. When immature the 
periphery is angular. Flindersian specimens from 100 fathoms 
and deeper are smaller, more delicate in form and sculpture. 
One from 100 fathoms off Cape Pillar is a typical deep water 
form. 
C. columnarium Heclley & May 1908. “The Cape Pillar 
CaUiostoma.” PI. 1, fig. 2. Rather solid, imperforate, turb- 
inate, angled at the periphery; buff colour; three spiral keels ap- 
pear on the second whorl, then increasing in number but decreas- 
ing in strength, till behind the aperture they are represented 
by twenty engraved spiral lines extending from the suture to the 
centre of the base; the spiral keels are decussated by faint ob- 
lique growth lines; whorls five-and-a-half, including a protoconch 
of a whorl-ancl-a-half, which is tilted, malleated, and concluded 
by a small varix; aperture oblique, rhomboidal; outer lip simple; 
columella thickened, insertions joined by a thin callus. Height 
7.5, diam. 8 mm. Dredged in 100 fathoms off Cape Wiles. 
(Type locality — 100 fathoms, seven miles east of Cape Pillar, 
Tasmania). In general appearance this resembles C. legratidi 
Tenison-Woods, but differs by blunter keel and the distant en- 
graved spirals. 
C. hedleyi Pritchard & Gatliff 1901 (not C. ornatum Lam- 
arck [Trochus] from Port Elizabeth, South Africa). “Hedley’s 
Calliostoma.” PI. 1, fig. 3. Conical, imperforate, apex acute; 
yellowish-brown, with reddish markings either in maculations or 
spots; whorls eight, convex, often tumid below the well defined 
suture; protoconch smooth; first two adult whorls tre.llised; follow- 
ing whorls with spiral, irregularly granular threads of unequal 
size, usually six on the antepenultimate, increasing 'by division of 
some of them to eight on the penultimate whorl and twelve on the 
body whorl abov^e the periphery at the outer %, ttyelve to sixteen
