8 Mr. It. B. Hinds on some new species of Melania. 



III. — Descriptions of new species of Melania collected during 

 the Voyage of H.M.S. Sulphur. By Richard Brinsley 

 Hinds, Esq. 



1. Melania fumosa. Testa elongata, crassiuscula, laevigata, olivaceo- 

 fusea, unicolore, vel junioribus infra suturam strigis longitudina- 

 libus rufis ornata ; anfractibus paulisper rotundatis, superne late 

 subconcave coarctatis, lineis impressis sparsim et obsolete cinctis ; 

 spira erosa apud anfractum quartum ; apertura caerulescente. Axis 

 truncatus 29 lin. 



Hab. New Ireland ; in the streams about Port Carteret. 



2. Melania aspirans. Testa elongate subulata, laevigata, fusca, uni- 

 colore * anfractibus numerosis, subplanulatis, lineis arcuatis incre- 

 menti fere minute pliciformibus, ultimo ad basin striato ; sutura 

 lineis impressis comitata ; apertura caerulescente ; columella albida. 

 Axis 23 lin. 



Hab. Feejee Islands ; in the rivers. 



3. Melania Plutonis. Testa pyramidato-subulata, subturrita, laevi- 

 gata, nitida, aterrima, unicolore ; anfractibus paulisper rotundatis, 

 ultimo magno, rotundato ; apertura caerulescente. Axis 23 lin. 

 Hab. Feejee Islands ; in the rivers. 



Very pyramidal in its shape, and the last whorl displays a far 

 greater proportion than is usual ; otherwise its characters are per- 

 fectly passive. The apex is erose to the fifth or six whorl. 



4. Melania figurata. Testa elongate subulata, laevigata, polita, fulva ; 

 anfractibus numerosis subrotundatis, superne strigis rufis longitu- 

 dinalibus, infra lineis interrupts transversis seriatim dispositis 

 ornatis, infra suturam pliciferis, ultimo ad basin striato ; apice 

 eroso ; apertura caerulescente. Axis 22 lin. 



Hab. New Ireland ; in the streams. 



The ornation of this species is eminently distinguishing ; other- 

 wise it is a smooth, elongated, tawny shell, like many others. The 

 middle and inferior portions of each whorl are adorned with trans- 

 verse rufous interrupted lines, disposed in regular series round 

 the shell, and present a pretty appearance on its pale yellow 

 semitransparent surface. 



5. Melania picta. Testa elongate subulata, fusca; anfractibus nu- 

 merosis, subplanulatis, plicatis, transversim sulcatis, strigis rufis 

 longitudinalibus ornatis, infra suturam uniseriatim tuberculatis ; 

 apertura caerulescente. Axis 19 lin. 



Hab. New Ireland ; in the streams. 



This species closely resembles M. subulata of Sowerby's ' Genera/ 

 not of Lamarck ; the figure there given does not represent some 

 of the characters dwelt on in the above description, and I am not 

 aware that a diagnosis anywhere exists.
