44 CYPRM&. 



osis, ad sulcum nodosis ; sulco an gusto ; marginc dextro 

 reflexo, roseo ; basi convexa ; columella antice et postice 

 varicosa ; sulco columellari lato, dentato, antice expanso ; 

 apertura lata. 



Note.— The specimen here figured from the collection of 

 Miss Saul, is the finest known. It is described by Mr. Gray 

 as intermediate between australis and rosea. 



152. pisdm, Gash., (f. 448, 449). — C. testa sphaaroidali, pal- 

 lescente ; costellis prominentibus. ex apertura ad lineam 

 dorsalem decurrentibus et in lineam atbenuatam terminanti- 

 bus ; dentibus prominentibus ; sulco columellari lato ; aper- 

 tura latiuscula, postice flexuosa; basi rotundata ; margine 

 externo incrassato, supra extremitates extenso ; extremitati- 

 bus crassis ; linea dorsali profunda, ex extreniitatibus posticis 

 ad anticam testae partem continua. 



Note. — The type specimen from the collection of Mr. 

 Taylor, late Gaskoin, is a pale coloured, but not a white 

 shell. The ribs are disposed rather transversely, i. e. less 

 than usually radiated, and terminate rather thinly at the 

 dorsal groove, their ends intercalating alternately. The 

 dorsal line is long. 



153. sulcata, Gask., (f. 454, 455). — C. testa ovato-globosa, 

 ventricosa, alba, ; basi rotundata, ; apertura latiuscula, postice 

 incurva, canalibus profundis et latis ; dentibus eequalibus ; 

 labii externi circa triginta, lateris columellaris viginti, supra 

 columellam continuis, marginem internum serratum forman- 

 tibus ; costellis prominentibus, plerumque ad impressionem 

 dorsalem terminantibus, pseudo-costellis ad utramque extre- 

 mitatem circa decern ; sulco columellari lato, profundo, mar- 

 gine externo prominente acuto ; extremitatibus obtusis, 

 crassis ; spira conspicua, ; impressione dorsali conspicua. 



Note. — Sulcata is very globose, with a slight dorsal de- 

 pression, more coarsely ribbed than formosa, which has no 

 dorsal groove. The posterior callus of the inner lip is pecu- 

 liarly small and sharp, and the columellar sulcus curiously 

 expanded. The type in Mr. Taylor's (late Gaskoin's) collec- 

 tion has rather the appearance of a partially formed shell. 



154. pulex, Sol, (f. 492, 493, 494).— C. testa, ovato-sub- 

 pyriformi, tenuiuscula, ventricosa ; dorso fusco- vel cinereo- 

 purpureo, medio lsevigato vix sulcato, ad latera costellis 

 albidis tenuibus radiatim lirato ; spira frequenter conspicua;
