South Australian Shells. 
This description recalls that of C. yatesi Crosse Var. B., Gulf 
St. Vincent, 14 fathoms; also MacDonnell Bay, Robe, and Beach- 
port, 150 fathoms. 
C. raphaeli Tenison-Woods 1876. “Raphael’s Clanculus!* 
Small, depressedly conical, rather solid; blackish olive, but tes¬ 
sellated with white at sutures; whorls four to five, flattened,, 
girdled with irregular spiral granulose lirae, sometimes alternat¬ 
ing and sometimes with minute granulose lines intervening, gran¬ 
ules larger at the margins; shell covered all over with minute 
transverse oblique lines; last whorl subacutely angular at the peri¬ 
phery; suture canaliculate; base flattened, ornamented with spiral 
granulose lines and oblique striae; umbilicus white; mouth quad¬ 
rate, silvery, pearly, conspicuously lirate; columella wide, con¬ 
spicuously tuberculate anteriorly; lip dentate. Height 6, diam. 6 
mm. Beach. Gulf St. Vincent. (Type locality—George’s Bay, 
Tasmania). This is probably a variant of C. yatesi Crosse, 
C. philomenae Tenison-Woods 1875. Depressedly conical, 
white; whorls five, at the suture canaliculate, concave, with both 
margins beaded, within the margins three to four lirate; lirae with 
round shining granules, interstices very finely obliquely striate; 
last whorl acutely angulatc and margined; base flat, spirally 
granulosely lirate; aperture obliquely squared; outer lip lirate 
within; columella unidentate and corrugated; umbilical margin 
spirally dentate. Height 10, diam. 11 mm. Gulf St. Vincent* 
(Type locality—Tasmania). A very distinct white shell with 
moniliferous whorls rising in stages. (Tenison-Woods). This al¬ 
so is probably a variant of C . yatesi Crosse. 
C. purpuratus Pilsbry 1889 (= C. yatesi var. purpuratus 
Pilsbry). “The Purple Clanculus.” Smaller but more solid 
that C. yatesi yet rather larger than C. dunkeri ; uniform deep 
purple; uppermost lira of granules much the largest, so that the 
upper part of each whorl projects abruptly beyond the lower part 
of the whorl above, as in yatesi , which character separates it 
from typical dunkeri; mouth oblique; columella subcanal iculate- 
posteriorly without teeth on its free edge, has a large sometimes 
bifid tubercle at anterior extremity; outer lip lirate-dentate all 
round and is thick and the aperture somewhat contracted by 
the dentations; even when quite small the mouth has the above 
characters, whereas in yatesi the shell is nearly lull grown before 
mouth is well formed. Height 8, diam. 11 mm. Gulf St. Vin¬ 
cent to Streaky Bay, beach and dredged to 55 fathoms. (Type 
locality—Tasmania). Like C. yatesi Crosse, this shell has two 
well tuberculate ribs and three less tuberculate between; the 
mouth however is rather more strongly dentated.
