S.A. NAT., VOL. XVI. 
April IOtii, 193S. By Bernard C. Cotton and F. A. Godfrey. 
from Western Australia. (Type locality — unknown. We desig- 
nate Port Victor, S.A.). The straightly conical form, flat base, 
indented around the axis, and the details of sculpture, easily 
separate it from allied forms. 
C. rubiginosum Valenciennes ( Trochus ) (— T. nobilis Phil- 
ippi 1846, preoccupied by Muenster 1835). PI. 1, fig. 8. “The 
Rusty Calliostoma.” Imperforate, acutely conical, rather thin; 
whitish buff, radiately flamed with brown and reddish; whorls 
ten, plane, protoconch eroded, smooth; adult whorls spirally 
cingulate, cinguli six, granose, the upper five cinguli small, lower 
eingulus wider, more prominent, subcrenate; last whorl acutely 
carinated; base, concentrically encircled by about seven or eight 
granose cinguli, alternately buff and rose coloured; mouth sub- 
quadrate, columellar lip spirally plicate; columella subarcuate, 
base subnodose, with a parallel groove. Height 22, diam. 22 
mm. Dredged alive at all depths from 9-22 fathoms in Back- 
stairs Passage, Gulf St. Vincent, Investigator Straits, and Spencer 
Gulf; one dead and broken shell was dredged in 150 fathoms 
off Beachport. Beach, uncommon, St. Francis Island. Also 
Western Australia — Albany beach 14.25 x 13 mm., and frag- 
ments up to 23 mm. in diameter; Geographe Bay beach 17.5 x 
16 mm.; dredged, Ring George Sound, and off Bunbury, 12-22 
fathoms. (Type locality— Western Australia. We designate 
Kino- George Sound). Specimen illustrated 30 mm. x 28 mm. 
C. splendidum Philippi. “The Splendid Calliostoma.” 
Rather sharply conical, somewhat swollen; whitish, variegated 
and spotted throughout with orange-yellow and purple-rose; 
whorls convexly sloping, regularly grain-ridged throughout. 
Height 30, diam. 27 mm. Dredged— Gulf St. Vincent, depth un- 
certain (Verco MSS) and Encounter Bay. (Type locality— 
Australia.' We designate Gulf St. Vincent). In colour this spe- 
cies partakes very much of the character of the preceding (rubi- 
ginosum), the purple-rose being more conspicuous, and broken 
up into blotches. The shell is of rather a lighter, more tumid 
growth, with the basal ridge more prominent than the rest 
(Reeve). 
C. ciliare Menke 1843 ( Trochus ) (= Zkyphinus castra 
Reeve 1863). PI. E fig. 9. Pyramidal, imperforate; fulvous, 
with red spots along the suture; transversely striate, decussated 
by very delicate striae; base plane; whorls flat, margined be- 
’ low, ciliate-fimbriate above; mouth ovate-lanceolate, outer lip 
callous-margined inside. Height 24, diam. 30 mm. Uncommon, 
dredged, Investigator Straits, Gulf St. Vincent, Backstairs Pas- 
sage, 13-17 fathoms; also Western Australia — Swan River, Es- 
perance, on Beach. (Type locality — North-west coast of Aus-
