3. Tuebinella picta. PI. VII. Fig. 9. Turb. testa ovato-fusiforini, medio ventricosa, anfractibus 

 transversim sulcatis, longitudinaliter obtuse plicato-costatis, superne concavis, deinde tuberculis compressis, 

 quorum supremis majoribus cingulatis ; aperturse fauce striata ; alba, maeulis numerosis nigricante-fuscis, 

 li neisque transversis coccineis et luteis pulcherrinie picta, columella fusco-rosacea. 



Hab. Feejee Islands. 



A pretty species, of rather solid growth, extremely richly painted. 



The animal of Turbinella cornigera is of a deep purple, finely marbled with white, the colours being 

 fainter towards the margin of the foot. The eye is distinct and well formed, having a black pupil and iris 

 of a light yellow colour. It crawls with deliberation and with apparent difficulty, appearing to labour 

 under the weight of its heavy shell as a tortoise does under that of its carapace. It is, moreover, of a very 

 timid disposition ; shrinking also, like a tortoise, quickly within its shell on the slightest alarm. The specimen 

 from which the foregoing observations were taken, was procured in about a fathom water, from a weedy 

 bottom, on the shores of Bilhton, an island in the Java Sea, between Borneo and Sumatra. 



The only notice in M. Bang's 'Manuel' is "Animal tres imparfaitement connu." This species must 

 vary in colour, as Quoy (Voy. Astrol.) states that the animal is " pale olive, darker spotted." Singularly 

 enough, Quoy in his figure, as copied by Mrs. Gray ('Figures of Molluscous Animals/ t. 8. f. 8), has 

 altogether omitted the operculum, which forms such a conspicuous appendage to the foot. It is a large, 

 thick, dense, nearly opake, claw-shaped operculum, composed of horny laminae, and is free at its posterior, 

 curved, sharp-pointed extremity, like the operculum of Fasciolaria Tarentina, according to Delia Chiage 

 (Mrs. Gray's ' Figures of Molluscous Animals/ t. 8. f. 4). A. A.

1. Ceeithium articulatum. PI. X. Fig. 14. Cer. testa subulato-turrita, solida, anfractibus planu- 

 latis, subobsolete varicosis, transversim regulariter sulcatis, apertura parviuscula ; livido-albicante, varicibus 

 subobscure albis, anfractuum margine superno rufo-fusco longitudinaliter lineato et maculato, anfractibus 

 infra transversim articulatis. 



Hab. Coast of Borneo, China Sea. 



Each whorl has a narrow collar, as it were, round the upper part, in which the markings 

 are longitudinal, while below they are transverse.

 impressis, anfractibus longitudinaliter nodoso-plicatis, transversim sulcatis, anfractu ultimo lativaricoso, 

 canali retrorsum valde producto, apertura parva ; fuscescente-spadicea, anfractuum margine superno rufo 

 maculato. 



Hab. Korea. 



Readily distinguished by the elongately produced structure of the canal.
