32 ZOOLOGY OP THE VOYAGE OE H.M.S. SAMAEANG. 



11. EBURNA, Lamarck. 



An interesting drawing was made of the living Eburna areolata, Lamarck, but no new 

 species were collected of the genus. It agrees in all respects with the generic description of 

 the animal given by M. Deshayes (Anim. sans vert. vol. x. p. 231), and is only inserted here 

 for the sake of its specific characters. 



1. Ebukna akeolata. PI. VIII. Pig. 5. Lamarck, Anim. sans vert. vol. x. p. 235. Eburna 

 tessettata, Swainson. Head flat, extended ; tentacles very long and slender ; eyes consisting of a yellow- 

 iris and black pupil mounted upon pedunculated swellings on the outer base of the tentacles ; siphon large, 

 fleshy and slightly curved ; foot long, fleshy and robust, acuminated behind and carrying a horny oper- 

 culum. Colour dull pinkish-white, sprinkled with large, light brown, irregular blotches; siphon and 

 tentacles mottled with spots of the same colour. 



Hab. China Sea ; from mud at the depth of fourteen fathoms. 



It is extremely rare to find any sort of concordance between the colouring of a rnollusk 

 and its shell. In the present instance there is a characteristic resemblance in this respect. 



12. BUCCINUM, Linncens. 



1. BucciNtnn hinnulus. PI. VII. Pig. 10 a, b. Bucc. testa ovato-turbinata, ventricosa, basi con- 

 torta et recurva, anfractibus septem, transversim crebriliratis, superne angulato-declivibus, ad angulum 

 exiliter nodulosis ; albida, aiu'antio-fusco sparsim maculata et strigata. 



Hab. Cagayan-Sooloo. 



Closely encircled throughout with contiguous slightly convex ridges, promiscuously 

 blotched with rich orange chestnut upon a white ground. 



2. Buccintjm clathratum. PL XL Pig. 12. Bucc. testa fusiformi-oblonga, crassiuscula, anfrac- 

 tibus septem, superne tumidiusculis, liris longitudiiialibus et transversis undique creberrime clathratis, 

 columella lamina callosa induta, apertura angusta, labro incrassato, superne vix siuuato ; fuscescente-alba, 

 obscure bi- trifasciata. 



Hab. Cape of Good Hope ; dredged from the depth of a hundred and thirty-six fathoms. 



This interesting deep-water species, and that which follows, approximate to the form 

 distinguished by Bivona as a genus under the name Pisania. It is of rather solid growth, 

 very closely sculptured throughout with lattice-work. 



3. Buccinum mitrella. PI. XL Pig. 13. Bucc. testa anguste fusiformi, spira exserta, anfractibus 

 octo, convexo-planis, lineis elevatis, longitudinaliter arcuatis et transversis subtiliter cancellatis, apertura 

 angusta, breviuscula, labro subincrassato, superne vix sinuato ; alba, maculis subquadratis spadiceis obscure 

 tincta. 



Hab. China Sea ; from ten fathoms.
