CLANCULUS CARINATUS, A. Adams, Proc. Zool. Soe. 1851, 
p- 162; Tryon, vol. xi. pl. 14, fig. 24-26.—Port Elizabeth. 
CLANCULUS PUNICEUS, Philippi, Conch. Cab. p. 73, pl. 
14, fig. 2.—Natal coast (Krauss). Distribution: Red Sea, 
Zanzibar, Senegal, &e. I have not met with this species 
among South African shells; it is nearly allied to, if not a 
mere variety of C. Pharaonis.

Conch. 1889, vol. vi. p. 11, pl. 1, fig. 16.—Port Elizabeth. 
CLANCULUS WALTONE, Sowerby, n. sp., pl. 2, fig. 45. 
—Testa breviter conica, fuscescens, maculis minutis nigro- 
fuscis irregulariter aspersa; anfractus 54, convexiusculi, 
liris spiralibus granulatis (in anfr. penult. 4, lira minima 
interveniente) ornati, sutura canaliculata sejuncti ; anfractus 
ultimus obtuse angulatus; basis leviter convexa, liris granu- 
latis circ, 9 ornata; umbilicus profunde excavatus; columella 
obliqua, supra et infra angulata; apertura leviter obliqua, 
subquadrata, fauce iridescens. 
Diam. 11; alt. 84 millim. 
Hab. Port Elizabeth (Crawford). 
Somewhat resembling C. carinatus and C. Laceyi, with 
the ridges crisply granulated. In form it is more elevated 
and inflated than CU. carinatus. 
CYCLOSTREMA ROTUNDATA, Sowerby, n. sp., pl. 2, fig. 47. 
—Testa orbiculata, anguste umbilicata, albida, subpellucida ; 
spira obtusa, sutura canaliculata; anfractus 4, convexi, 
spiraliter striati; anfractus ultimus rotunde convexus : aper- 
tura leviter obliqua, subcircularis. 
Diam. 24; alt. 14 millim. 
Hab. Port Elizabeth. 
A little white shell, of which the true generic position 
is uncertain. The species varies a good deal in form, and 
in the width of the umbilicus, which in some specimens is 
nearly closed. 
CYCLOSTREMA INFLATA, Sowerby, n. sp., pl. 11, fig. 48.— 
Testa inflata, anguste umbilicata, tenuis, alba; spira parva, 
acutiuscula, gradata; sutura profunda; anfractus 4, primi
