 Inhabits the Indian and European Seas. Linnaeus. Coasts of 

 Britain. Lister. Persia. Martini. Norway, Spain, and 

 France. Favaniie. 

 Shell about an inch and a half long, and two lines in diameter 

 at the broader end, smooth, glossy, pervious, and tapering to 

 a small point ; Gmelin's D. arietinum, which is said to dif- 

 fer in being only one-eighth part as large and more curved, 

 is most probably the young of this species. 



CORNEUM. 7. Shell slightly curved, taper, mter- 

 rupted, and opake.

Inhabits the African Ocean. Linnaus. 



Linnasus has not given any reference, and to the above specific 

 character only adds that this species is very like D. EntaliSy 

 but is of a dark horn-colour, and often interrupted ; the shell 

 figured by Schroeter is an inch and a quarter long, and differs 

 from D. Entalis in being cylindrical, and in having a round- 

 ed obtuse summit. 



POLITUM. 8. Shell slightly curved, taper, and con- 

 tinuous, with much crowded annular striae.

Inhabits India. Linnceus. Coasts of Sicily. Martini. 



This shell is of the same size, and has nearly the appearance of 

 D. Entalis, from which it is distinguished by its crowded 

 transverse annular striae ; it is generally milk-white, but some- 

 times of a pale rose-colour, and the whole surface has a po- 

 lished appearance. 



EBURNEUM. 9. Shell slightly curved, taper, and 

 continuous, with remote annular striae.
