5( > ZOOLOGY OF THE VOYAGE OF THE SULPHUR. 



subturrita, laevigata, nitida, aterrima, unicolore ; anfractibus paulisper rotundatis, ultimo magno, 

 rotundato ; apertura casrulescente. 



Inhab. Feejee Islands. In the rivers. 



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

 tion than is usual ; otherwise its characters are perfectly passive. The apex is 

 erose to the fifth or sixth whorl. 



227. Melani a figurata, Hinds, 1. c. p. 8, (Plate XV. fig. 13.) Testa elongate subulata, laevi- 

 gata, polita, fulva : anfractibus numerosis subrotundatis, superne strigis rufis longitudinalibus, infia 

 lineis interruptis transversis seriatim dispositis ornatis, infra suturam pliciferis, ultimo ad basin striato; 

 apice eroso ; apertura casrulescente. 



Inhab. New Ireland. In the streams. 



The ornation of this species is eminently distinguishing ; otherwise it is a 

 smooth, elongated, tawny shell, like many others. The middle and inferior por- 

 tions of each whorl are adorned with transverse rufous interrupted lines, disposed 

 in regular series round the shell, and present a pretty appearance on its pale yel- 

 low semitransparent surface. 



228. Melania picta, Hinds, 1. c. p. 8, (Plate XV. fig. 3.) Testa, elongate subulata, fusca; 

 anfractibus numerosis, subplanulatis, plicatis, transversim sulcatis, strigis rufis longitudinalibus 

 ornatis, infra suturam uniseriatim tuberculatis ; apertura. casrulescente. 



Inhab. New Ireland. In the streams. 



This species closely resembles 31. 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. 



229. Melania luctuosa, Hinds, 1. c. p. 9, (Plate XV. fig. 1.) Testa subulata, turrita fusca; 

 anfractibus planulatis, fere subconcavis, transversim lineis impressis cinctis,strigis rufis longitudinalibus 

 interruptis ornatis; spira paulisper erosa ; apertura casrulescente. 



Inhab. Feejee Islands. In the rivers. 



So contracted are the whorls here as in some cases to be not only flattened 

 but even concave, particularly towards the last whorl. 



230. Melania perpinguis, Hinds, 1. c. p. 9, (Plate XV. fig. 2.) Testa, elongata, fusca., strigis 

 rufis longitudinalibus plerumque ornata ; anfractibus rotundatis, subturritis, lineis transversis im- 

 pressis exculptis ; spira. subplicata, apud extremitatem erosa ; apertura casrulescente, ad peripheriam 

 ustulata. 



Inhab. Feejee Islands. In the rivers. 



231. Melania occata, Hinds, 1. c. p. 9, (Plate XV. fig. 5.) Testa ovata, elongata, lutescente ; 

 anfractibus paucis, rotundatis, exaratis, lyris intermediis angustis acutis ; spira apud anfractum 

 quartum erosa. ; apertura casrulescente. 



Inhab. River Sacramento, California.
