Shell oblong ovate, ventricose, behind produced, whitish flesh 

 colour, mottled, sandy, ornamented with numerous small reddish 

 black spots; the dorsal line yellowish; sides whitish flesh colour, 

 spotted with red and black, thickened, the outer one rounded, the 

 inner obtusely angular ; base white, flattish; aperture rather di- 

 lated in front ; teeth of the upper lip narrow, close, slightly 

 extended on the inner lip nearly the whole length ; of the outer 

 large, distinct; columella plaited, concave in front. 



30. Cyprcea sub-rostrala. 



Testa ovali-ovata, ventricosa, alba, spira convexa, basi convex- 

 iuscula ; extremitatibus sub-productis, marginatis ; lateribus sub- 

 incrassatis rotuudatis ; columella Iasvi, plana profundi. 



Nehoue. Mus. Sowerby. 



Shell oval ovate, nearly globular, spire convex, distinct ; base 

 convex ; sides rather thickened, obtusely margined ; extremities 

 rather produced, distinctly margined ; aperture rather large, front 

 concave ; columella smooth, front flat, smooth, deep ; axis J-§, 

 diameter ^ of an inch, sometimes larger. 



** Cyvrjem Ver.e. — Shell, when young, smooth, banded ; 

 when perfect, polished, smooth, edge entire. Inner lip, close to the 

 columella, leaving no, or scarcely any, concave space ; the plaits 

 carried over the columella. 



. Obs. In almost all the species of this section, there is no de- 

 pression on the columella, but the plaits run over it without any 

 interruption ; and in those few species that do possess any depres- 

 sion, it is very different in form from the similar part in the for- 

 mer section, to which they cannot be referred, as it would require 

 that some very approximating species, as C. caurica^ and C. vario- 

 laria, &c. should be separated from one another. Some of the 

 species, as, C. dsellus, C. inierrupta, C. quadrimaculata, C. Hi- 

 rundo, C. stolida, and C. Moneta, are tubercular, or ribbed at the 

 base ; but they have no depression on the columella, and conse* 

 quently cannot be confounded with the last section, to which they 

 have considerable affinity.
