Linnaeus describes this species to be about as large as a hazel- 

 nut, white, with an ovate smooth aperture, and the umbili- 

 cus minute and oblong. Gualter, t. 64. f. H, which he has 

 alone quoted^ has much the appearance of a Turbo, and has

 Bay of Naples. Ulysses. 



This shell appears by the figure, for the size is not noticed in 

 the description, to be about a quarter of an inch long, with 

 the breadth rather exceeding the length, and of an uniform 

 rose-colour ; Ulysses says it is slightly tuberculated, and has 

 the aperture toothed, and the lip serrated within. 



PATHOLATus. 41. Shell sub-conical, transversely 

 striated, and the whirls produced and flattish ; 

 umbilicus small.
