I use the term obvallata instead of obvelata, believing it 

 to be the word which Lamarck intended to characterize 

 the peculiar growth of this shell. Those who think with 

 me that such was the case, wiU adopt it without prejudice 

 to the authenticity of the species. 



Species 70. (Mus. Cuming.) 



Cypr/EA nucleus. Cypr. testa ovatd, extremitatibus pro- 

 ductis et rostratis, dorso noduloso, nodidis, prtecipue 

 lateraUbus, liris coadunatis, basi convexd, dentibus par- 

 vis, in liris angustis per basem utrinque extensis ; sor- 

 dide albd, uodidis Urisque pallide ferruginosis.

The dorsal line of this species is represented by a rather 

 deep longitudinal groove. 



Species 71. (Mus. Cuming.) 



Cypr^a annulus. Cypr. testa ovatd, basi coitcavo-de- 

 pressd, lateribm incrassatis, declivibus, dentibus, for-

 gnineo circumcincto.

 Hab. Eastern Seas. 



There is no indication in tliis species of the oval in- 

 trenchment which characterizes the growth of the Cyprata 

 obvallata. 



Species 72. (Mus. Cuming.)

 iiicrassatis, medio tiirgidis, marginatis,foveolatis, den-

 albis, maculisque stellaribus fulto-rubidis sparsim or- 

 nato, lateribus basique fusco-rubidis, colore mpra mar-

A common species but one of the most richly and beau- 

 tifuUy colom-ed of the series.

 lateribus tnrgidis, sidmiarginatis, obscure foveolatis,
