MOLLUSCA. 33 



Characterized by the same idea of form and sculpture as the preceding species, though 

 materially distinct in detail. 



■I. Buccinum eilostjm. PL XI. Fig. 18. Bucc. testa acuminato-oblonga, crassiuscula, spirae suturis 

 canaliculars, anfractibus plano-convexis, lsevibus, lineis incisis subdistantibus transversim regulariter sulcatis, 

 columella arcuata, peculiariter abbreviata et truncata, niargine uniplicata, apertura antice dilatata, postice 

 subemarginata ; carnea et cinerascente, sulci's alternis rufo-fuscescentibus maculisque obscure bifasciata. 



Hab. China Sea. 



This shell, which is remarkably characterized by the abrupt truncature of the columella, 

 and by its anteriorly dilated aperture, might possibly belong to an animal generically distinct 

 from Buccinum. If such should prove hereafter to be the case, we propose to regard the 

 species as the type of a new genus, with the name Truncaria. 



5. Buccinum albipunctatum. PI. XL Fig. 21. Bucc. testa acurninato-ovata, anfractibus septem, 

 tribus oblique plicatis, ceeteris lsevibus, nitentibus, ad suturas subtiliter marginatis, apertura parviuscula, 

 labro subincrassato, lirnbo spinoso-crenulato, superne sinuate; pallide fulvescente, punctis minutis opaco- 

 albis seriatim notata, apice rosaceo. 



Hab. Island of Mindanao, Philippines ; on the shore. 



B. albipunctatum belongs to that section of the genus distinguished by Mr. Gray with 

 the title of Northia, of which B. pristis is the type ; and it is very closely allied to a 

 species improperly referred in the ' Conchologia Iconica' to the genus Pleurotoma, Sp. Ill, 

 P. Rissoides. 



13. CYLLENE, Gray. 



1. Ctllene lugubbis. PI. X. Fig. 10. Cyll. testa ovata, crassa, spira acuta, anfractibus undique 

 creberrime sulcatis, superne tumidis, subtiliter noduloso-plicatis ; intense castanea, labro albo, anfractuum 

 margine superiore albivariegata. 



Hab. Sooloo Islands. 



A fine stout species of this characteristic, but little known, genus, in which the whorls 

 are finely nodulously plicated round the upper part. 



2. Cyllkne pulchella. PI. X. Fig. 11. Cyll. testa ovata, crassiuscula, spira subacurninata, acuta, 

 anfractibus medio tumidis, transversim lineari-sulcatis, apicem versus subtilissime plicatis ; alba, flammis 

 pallide rosaceis obscure variegata, apice roseo. 



Hab. Borneo ; on the shore. 



An extremely delicately painted species, with light pink waves, and pink apex. 



14. PURPURA, Lamarck. 

 1. Puuptjea cuspidata. PL XL Fig. 35. Purp. testa abbreviato-ovata, spira brevi, acuta, anfrac-
