678 STROMBUS. 



is a rich brown, with three transverse white bands on the 

 body-whirl, and one on the other whirls, and on each a row 

 of remote tubercles ; the throat and pillar are white. Mul- 

 ler says it is sometimes yellow with brown bands, and has 

 described one Variety with a white line at tlie sutures in ad- 

 dition to these markings. Brnguiere, from its thickness, 

 doubts whether Lister and Chemnitz have been correct in 

 considering it a fresh-water shell.

Linnaeus, in the Mus. Reg. Lud. Ulrica, has described this shell 

 to be " turreted, sub-angulated, with smooth pointed no- 

 dules, and a single row of straight conical acute spines in 

 the middle of the whirls ; colour livid with ferruginous 

 spots ; aperture oblong, and not contracted at the base." 

 MuUer says that his Buccidum torridiim differs only in not 

 having any ferruginous spots, but Brnguiere in his descrip- 

 tion of Bnlimus muricatus, in the Encyclopedic Methodique, 

 p. 330, expresses a contrary opinion. Bruguiere there al- 

 ludes to a description of the Linnaean shell under the name 

 of Cerithe livide, but I cannot find any such species in his 

 Genus Ceritliium. The shell which Chemnitz has figured 

 is about an inch and a half long, and near an inch broad. 



C0STATU6. 43. Shell turreted, with the whirls lon- 

 gitudinally ribbed, and a spiral line on each ; 

 aperture sub-orbicular, and the outer lip ex- 

 panded.
