128 Cyprcea Solandri, Gray, Conch. Illust., f. 43. 



Shell reddish brown, with a light-coloured dorsal 

 groove, and a dark streak along each side of it ; ribs 

 prominent, wide apart, tuberculated at their dorsal ex- 

 tremities, mouth rather narrow, teeth of the outer lip 

 more numerous than in C. radians : margin generally 

 broad : length 0*7, breadth 0'55. Pacific Ocean. 



Ohs. This species is very much like radians, indeed 

 it is impossible to know which of the two, this or the 

 one we commonly call by that name, is the radians of 

 Lam. The principal difference is in the number of 

 teeth on the inner edge of the outer lip. 



129 radians. Lam., Wood's Cat. t. 17, f. 58. 



130 depauperata, JVobis, Conch. Illust., f. 49. 



Shell nearly orbicular, rather depressed, pale fawn 

 coloured, dorsal line narrow, distinct ; transverse ribs 

 few, distant, sometimes interrupted ; margins thickened ; 

 under side somewhat rounded ; ribs and teeth of the 

 outer lip more numerous and closer than those of the 

 inner: length 0*5, breadth 0' 4. 



The locality of this species, which does not appear 

 to be nearly related to any other is unknown ; very few 

 specimens have occurred. 



Genus, ERATO, Gray. 



Obs. I readily adopt this Genus, which appears to have 

 been first established by Risso, followed by Gray : 

 merely observing that it is a link connecting Cyprcea 

 with Marginella,
