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



The shell is subulate, with the inferior whorls obese, smooth and 

 polished ; the whorls about ten in number and slightly rounded ; 

 those towards the apex indistinctly plicated ; spire exserted and 

 scarcely eroded. The base colour is a pale yellow, densely crowded 

 with transverse angular dark red markings. 



12. Melania florata. Testa ovato-elongata, polita, cornea, tessellata ; 

 anfractibus paucis, subrotundatis, seriebus tribus macularum rufa- 

 rum quadratarum eleganter ornatis ; serie suprema praecipue max- 

 ima, intermedia minima ; anfractu ultimo ad basin punctato ; spira 

 erosa ; apertura cornea. Axis 6^ lin. 



Hab. New Ireland ; in the streams. 



This also is a pretty species with a pale surface, each whorl 

 being ornamented by three series of transverse reddish spots, of 

 which the superior is the largest and most deeply coloured ; the 

 two others are punctations of reddish spots, the inferior being in- 

 termediate in size. Very delicate strise, not easily recognizable, 

 traverse the shell transversely. 



13. Melania gaudiosa. Testa ovato-elongata, laevigata, polita, cornea; 

 anfractibus octonis subplanulatis, unicoloribus ; spira oblique pli- 

 cata, ad extremitatem erosa ; apertura ovali, cornea. Axis 9 lin. 

 Hab. New Ireland ; in the streams. 



Approaches somewhat closely, in general character, the Ame- 

 rican shell, M. plicifera. 



14. Melania pyramidata. Testa elongate subulata, gracili, nitida, 

 cornea ; anfractibus decern subplanulatis, transversim distanter 

 striatis, superne intra suturam fusco anguste fasciato, ultimo ad 

 basin puncticulato ; spira versus extremitatem plicata, erosa ; aper- 

 tura ovali. Axis 9 lin. 



Hab. New Ireland ; in the streams. 



15. Melania latebrosa. Testa ovata, elongata, sordide fusca ; anfrac- 

 tibus perpaucis, rotundatis, lineis impressis transversis instructis, 

 erosis usque ad penultimum ; apertura parva, ovali, caerulescente. 

 Axis 8 lin. 



Hab. New Ireland ; in the streams. 



A small obese shell, with little to distinguish it beyond its few 

 rounded whorls furrowed transversely with parallel impressed 

 lines, and its comparatively small, neat, oval aperture. 



16. Melania pugilis. Testa spinosa, elongate ovata, fulva ; anfrac- 

 tibus circa novem, rotundatis, superne spiniferis, infra suturam 

 serie unica macularum rufarum, inferne seriebus duabus minoribus 

 cinctis, ultimo ad basin multiseriato, spinis distantibus, ad peri- 

 pheriam quinque, truncatis, linea angulata alligatis ; spira subtrun- 

 cata ; apertura oblique ovali, subattenuata, albida. Axis 14 lin.
