MOLLUSC A. 57 



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. 



232. Melania mcBsta, Hinds, 1. c. p. 9, (Plate XV. fig. 4.) Testa, ovata, elongata, fuliginea, 

 infra epidermidem albida; anfractibus rotundatis, supeme angulatis et excavatis, transversim lineis 

 impressis striatis ; spira apud extremitatem erosa; apertura ustulata, ad basin subtruncata.

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 below. The margins of the aperture have the colour of burnt umber. 



233. Melania verrucosa, Hinds, 1. c. p. 9, (Plate XV. fig. 7, 8.) Testa, subulata, subturrita, 

 Jutea; anfractibus octonis planulatis, longitrorsum obtuse plicatis, lineis tribus transversis intersectis, 

 harum intervallis obtusis, quadratis, tuberculosis; apice vix eroso; apertura elongata, lutescente.

234. Melania fulgurans, Hinds, 1. c. p. 9, (Plate XV. fig. 6.) Testa, obeso-subulata,, laevigata., 

 polita, lutescente, strigis rufis angulatis fulmen simulantibus conferta ; anfractibus decenis subro- 

 tundatis ; spira. laeviter plicate, exseita, vix erosa; apertura ovali, cserulescente.

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



235. Melania florata, Hinds, 1. c. p. 10, (Plate XV. fig. 22.) Testa ovato-elongata, polita, 

 corned, tessellata ; anfractibus paucis, subrotundatis, seriebus tribus macularum rufarum quadratarum 

 eleganter ornatis ; serie suprema praecipue maxima, intermedia minima ; anfractu ultimo ad basin 

 punctato ; spira. erosa, ; apertura corned.

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

 mented by three series of transverse reddish spots, of which the superior is the 

 largest and most deeply coloured ; the two others are punctuations of reddish spots, 

 the inferior being intermediate in size. Very delicate stria?, not easily recog- 

 nizable, traverse the shell transversely. 



236. Melania gaudiosa, Hinds, 1. c. p. 10, (Plate XV. fig. 19.) Testa ovato-elongata, laevigata, 

 polita, cornea ; anfractibus octonis subplanulatis, unicoloribus ; spira oblique plicata, ad extremitatem 

 erosci; apertura ovali, cornea.
