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



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

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

 gis rufis longitudinalibus interruptis orriatis ; spira paullsper 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 rufis longitu- 

 dinalibus plerumque ornata ; anfractibus rotundatis, subturritis, 

 lineis transversis impressis exculptis ; spira subpHcata, apud extre- 

 mitatem erosa ; apertura caerulescente, 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 quartum erosa ; apertura cserulescente. 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 shghtly 

 disposed to elongate in the manner of lo. 



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 occm's in this species, is shared \dt\x a few others. In the 

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

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

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

 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 rufis angulatis fulmen simulantibus conferta ; an- 

 fractibus decenis .subrotundatis ; spira leeviter plicata, exserta, vix 

 erosa; apertura ovali, caerulescente. Axis 13 lin. 



Hab. New Ireland ; in the streams. 



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