Mr. R. B. Hinds on some new species of Melania. 9 



6. Melania luctuosa. Testa subulata, turrita, fusca ; anfractibus pla- 

 nulatis, fere subconcavis, transversim lineis impressis cinctis, stri- 

 gis rufis longitudinalibus interruptis ornatis ; spira paulisper erosa ; 

 apertura cserulescente. Axis 13 lin. 



Hab. 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. 



7. Melania perpinguis . Testa elongata, fusca, strigis runs longitu- 

 dinalibus plerumque ornata ; anfractibus rotundatis, subturritis, 

 lineis transversis impressis exculptis ; spira subplicata, apud extre- 

 mitatem erosa ; apertura cserulescente, ad peripheriam ustulata. 

 Axis 14 lin. 



Hab. Feejee Islands ; in the rivers. 



8. Melania occata. Testa ovata, elongata, lutescente ; anfractibus 

 paucis, rotundatis, exaratis, lyris intermediis angustis acutis ; spira 

 apud anfractum quartura erosa ; apertura caerulescente. Axis 12 lin. 

 Hab. River Sacramento, California. 



The rounded whorls are ploughed into numerous furrows, and 

 the intervening ridges are comparatively narrow and keel-shaped ; 

 the lower part of the aperture is somewhat dilated, and slightly 

 disposed to elongate in the manner of Io. 



9. Melania moesta. Testa ovata, elongata, fuliginea, infra epider- 

 midem albida ; anfractibus rotundatis, superne angulatis et exca- 

 vatis, transversim lineis impressis striatis ; spira apud extremitatem 

 erosa; apertura ustulata, ad basin subtruncata. Axis 15 lin. 

 Hab. Feejee Islands ; in the rivers. 



The slightly concave area of the whorl beneath the suture, 

 which occurs in this species, is shared with a few others. In the 

 present, it influences the shape of the aperture, straightens the 

 outer lip, provides it with an angle above, and truncates it be- 

 low. The margins of the aperture have the colour of burnt 

 umber. 



10. Melania verrucosa. Testa subulata, subturrita, lutea ; anfrac- 

 tibus octonis planulatis, longitrorsum obtuse plicatis, lineis tribus 

 transversis intersectis, harum intervallis obtusis, quadratis, tuber- 

 culosis ; apice vix eroso ; apertura elongata, lutescente. Axis 10 lin. 

 Hab. New Ireland ; in the streams. 



11. Melania fulgurans . Testa obeso-subulata, laevigata, polita, lu- 

 tescente, strigis runs angulatis fulmen simulantibus conferta ; an- 

 fractibus decenis subrotundatis ; spira lseviter plicata, exserta, vix 

 erosa; apertura ovali, cserulescente. Axis 13 lin. 



Hab. New Ireland ; in the streams. 



Few species of Melania have the pretensions to beauty of this.
