58 ZOOLOGY OF THE VOYAGE OF THE SULPHUR. 



Approaches somewhat closely, in general character, the American shell, 

 31. plicifera. 



237. Melania pyramidata, Hinds, 1. c. p. 10, (Plate XV. fig. 20.) Testa, elongate subulata, 

 gracili, nitidi, cornea; anfractibus decern subplanulatis, transversim distanter striatis, superne infra 

 suturam fusco anguste fasciato, ultimo ad basin puncticulato; spira. versus extremitatem plicata, 

 erosa; apertura ovali. 



Inhab. New Ireland. In the streams. 



238. Melania latebrosa, Hinds, 1. c. p. 10, (Plate XV. fig. 21.) Testa ovata, elongata, sordide 

 fusca; anfractibus perpaucis, rotundatis, lineis impressis transversis instructis, erosis usque ad penul- 

 timum ; apertura parva, ovali, cserulescente. 



Inhab. 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. 



239. Melania pugilis, Hinds, 1. c. p. 10, (Plate XV. fig. 17, 18.) Testa, spinosa, elongate 

 ovata, fulva; anfractibus circa novem, rotundatis, superne spiniferis, infra suturam serie unica 

 macularum rufarum, inferne seriebus duabus minoribus cinctis, ultimo ad basin multiseriato, spinis 

 distantibus, ad peripheriam quinque, truncatis, linea angulata alligatis; spira subtruncata. ; apertura 

 oblique ovali, subattenuata, albida. 



Inhab. New Ireland. In the streams. 



Shell ovate, pale yellow ; whorls ventricose, spiniferous, of an uniform colour 

 in the middle, above adorned with a single series of red markings, longitudinal or 

 nearly square, below with two series of smaller spots placed on bands slightly 

 paler than the neighbouring shell ; the last whorl exhibits at its base several 

 series of these articulated bands ; the spines are distant and truncated to near 

 their base ; about five occupy the circumference of a whorl, and an angular line 

 connects each with its neighbours ; the spire has scarcely lost more than its 

 extreme whorl by erosion, and the aperture is white, and in a slight degree 

 attenuated at its base. 



240. Melania lellicosa, Hinds, 1. c. p. 11, (Plate XV. fig. 15, 16.) Testa, spinosa, ovata, 

 valde truncata., fusca; anfractibus tribus rotundatis, transversim striatis, spiniferis, frequenter erosis; 

 spinis aculeiformibus, subrectis, ad basin decurrentibus ; spirS, apud anfractum antepenultimum 

 truncata ; apertura elongate ovali, subfusca. 



Inhab. Feejee Islands. In the rivers. 



Nearly allied to M. spinulosa, Lamarck, which is found in the rivers of 

 Timor.
