SOQTH AFRICAN MARINE MULLUSCA. 23 



This is a very distinct species and not comparable with any 

 of the known forms. Of the transverse Avhite lines dotted 

 with brown about a dozen are conspicuous to the naked eye, 

 but the narrower intervening ones are hardly visible except 

 with the aid of a lens. The spire, which is very little raised, 

 is whitish, streaked and spotted irregularly with brown. 

 The apex is peculiar, consisting of two convex convoluted 

 whorls which rise as a sort of mamilla above the rest. 



^Clionella confusa n. sp. PI. VII, fig. 2. 



Testa C. rosariee similis, sed major, anfractibus plerumque 

 minus convexis, striis spiralibus vix conspicuis, cingulo infra 

 suturam majori, colore diversa. Longit. 45 mm., diam. 14. 

 Aperture 12 longa, 6 lata. 



Hab. — Port Elizabeth, Algoa Bay. 



Shell elongate, of an uniform bright red or yellowish 

 colour ; whorls 10 ? (apex broken away), rather fiat, con- 

 stricted at the upper part, leaving a rounded girdle beneath 

 the suture, with about 14 slightly oblique costa) below the 

 constriction, by which they are interrupted, so that they are 

 only faintly indicated upon the cingulum above ; ribs upon 

 the body-whorl attenuated anteriorly, but disappearing upon 

 the snout ; suture a little oblique and wavy ; aperture more 

 or less rosaceous within ; columella curved, covered with a 

 thin whitish callus; outer lip distinctly but not deeply 

 notched at the constriction. 



This species has been confounded with C. rosaria. Reeve, 

 because of its bright red colour. Beeve's species, however, 

 appears invariably to have the cingulum at the upper part of 

 the whorls whitish, and more or less spotted with brown. 

 The whorls of that species are more convex, and are distinctly 

 transversely striated. It appears to be smaller also, the 

 largest specimen examined being only 25 mm. in length. It 

 is more variable in colour, sometimes bright red with a white 

 girdle, sometimes brown, mottled with white, or yellowish, 

 flecked with white dots.
