Inhabits 



Chemnitz has figured this shell about seven lines long, and six 

 broad, of a pale chestnut-colour with remote narrow darker 

 transverse stripes, and a white band spotted with chestnut at 

 the upper margin of the whirls. Chemnitz sa\s it resembles 

 ie Lima^oH rubane, which is described to be imperforated, 

 but Favanne adds, ' Quoique sans ombilic, cette coquille en 

 montre neanmoins quelquefois de legers vestiges.' 



DivARiCATus. 53. Shell ovate, sub-iimbilicated, 

 with the botly-whirl more remote, and the um- 

 bilicus nearly consolidated.

Inhabits the Mediterranean, and coasts of Norway. Linnaus. 



Linnaeus has not given any reference, and to the above short 



character only adds, that the shell is green with rows of red 



spots, and that the lower whirls are more remote than the 



upper. 



FUSCATUS. 54. Shell depressed-conical, with the 

 whirls contiguous, and finely striated trans- 

 versely ; aperture roundish, and the umbili- 

 cus sub-cylindrical.

Born describes this shell to be eighteen lines long, and only 

 half as broad, which is obviously erroneous ; and he says the 

 shell is of an olive-colour, with transverse brown and white 

 spotted bands, but there is not any white in his figure. 



VMBlLiCARis. 55. Shell conical-convex, with the 

 whirls slightly margined, and the umbilicus 

 cylindrical.
