A very beautiful shell, of an elegant pyramidal form, with 

 numerous regular varices, which in the upper whorls are 

 thin, but in the last whorl are much thicker and some 

 doubled. The umbilicus is large. The colour between the 

 varices is dull fawn, with two bands, which in the last whorl 

 are blended with purple. Mozambique and Swan River.

T. elongata, lajvi, umbilicata ; anfractibus rotundatis, con- 

 tiguis ; varicibus leevibus, decumbentibus, subnumerosis, 

 prope suturam sub-arcuatis, nonnullis crassis, pluribus 

 tenuis ; apertura magna, auriformi ; colore pallide fulvo, 

 inter varices, fasciis tribus fuscis. 



In general form resembling Sc. lineata of Say, but differ- 

 ing from it in having a wide umbilicus. The last whorl and 

 aperture are large in proportion to the size of the shell, in 

 which respect it differs from Sc. turricula ; it is prettily 

 coloured with three reddish brown bands ; the varices are 

 rather numerous, some rather thick, and others very thin.

T. elongata, umbilicata, plerumque transversim minute 

 striata ; anfractibus numerosis, rotundatis, gradatim crescen- 

 tibus ; varicibus sub-numerosis, plerumque tenuis, nonnullis 

 crassis ; apertura ovali, parva ; colore albo vel irregulariter 

 fulvo. 



The whorls are more numerous, and increase in size more 

 gradually than the last, the mouth is consequently smaller, 

 the ribs are irregular, differing from each other in thickness. 

 There are, in most of the specimens numerous transverse 

 stria?, which are wanting in others ; one variety is white and 

 strongly striated ; another is irregularly patched with light 

 brown, and nearly smooth. The latter variety only is 

 brought by Mr. Cuming from Catanuan Isl. Luzon, Philip- 

 pines. Both occur in the West Indies.
