MOLLUSCA. 7 



Inhab. Port Anna Maria, Nukuhiva, Marquesas. In from seven to ten 

 fathoms, among sand. 



Few specimens only of this species were obtained, but among them were 

 some which were constantly of an uniform paler colour. It somewhat resembles 

 C. marmoreus, and in some respects C. nobilis, to which it is, however, superior 

 in symmetry, and from which it may very readily be distinguished by several 

 characters. 



4. Conus voluminalis, (Plate I. fig. 8, 9.) Testa, ecoronata, conico-involuta, superne valde 

 angulata, albida, maculis rufis longitudinalibus interruptis ornata ; spira. plano-depressa, persaltum 

 conico-mucronata, striata, maculis spiraliter adscendentibus ; epidermide subdiaphana, lineis vestitis 

 approximatis ; circa basin sulcata. 



Inhab. Straits of Malacca. In eleven fathoms, among mud. 



5. Conus patricius, Hinds, Ann. Nat. Hist. v. 11. p. 256, (Plate I. fig. 1,2.) Testa pyriformi, 

 tumida; spira acuminata, minute tuberculata vel coronata; aufractu ultimo striato, superne plicifero, 

 inferne valde contractato ; apertura lineari ; labro tenui, acuto ; epidermide fulva. laevi induta. 



Inhab. Gulf of Nicoya. In seven fathoms, among sandy mud. 



The spire is very elegantly and minutely coronated, and the angle of the last 

 whorl is covered with small neat folds ; below it is suddenly contracted, so as to 

 impart a very correct pyriform shape. 



6. Conus calebs, Hinds, Ann. Nat. Hist. v. 11. p. 256. 



Placing implicit reliance on Mr. Reeve, when he was engaged on his mono- 

 graph of Conus, and being desirous of rendering it as complete as any information 

 in my possession could make it, I was induced to describe this shell as a new 

 species ; and though its proportions and epidermis are somewhat striking, I fear it 

 must be regarded as the young only of Conus terebellum. 



7. Conus californicus, (Plate I. fig. 3, 4, 5.) Testa, ecoronata, subfusiformi, involuta, laevi, pal- 

 lida vel ferruginea., lineis rufis regulariter induta, maculis parvis lacteis conspersa; spira conica, elata; 

 labro subarcuato, acuto ; epidermide castanea velutina. 



Inhab. Bay of Magdalena, California. In seven fathoms, on a sandy floor. 



A somewhat small species, when clothed in its velvety epidermis reminding 

 one strongly of a large filbert, and when this is removed displaying a pale iron- 

 rust coloured surface, traversed at equal distances by numerous reddish lines, 

 and with small milk-white spots occasionally scattered about in irregular 

 clusters.
