Inhabits the coasts of China. Chemnitz. 



Shell five or six inches long, and one-fourth as broad, of a 

 greyish or brownish white or pale chestnut-colour ; it has 

 from twenty-four to thirty, or according to Born, thirty-six 

 much rounded whirls, with about ten sharp ribs on each, and 

 fine intermediate striae ; it was probably confounded by Lin- 

 naeus with T. Terebra, from which it differs in having the 

 whirls much more numerous and more rounded, and the ribs 

 more elevated and crowded, as also in its larger size. 



VARIEGATUS. 136. Shell turreted, with flattish 

 whirls, and seven obsolete striae on each.

Linnaeus, without any description besides that which is con- 

 tained in the above short character, has quoted Bonanni Rec. 

 ^. f. 122, and Seba, iii. t. 56. f. 26, 34, 31 and 33, which 

 have much the appearance of T. imbricatus. Martini 

 doubted whether his T.marmoreus might not be this species, 

 but that shell agrees better with the Linnsean definition of 

 T. exoletus. 



UNGULiNus. 137. Shell turreted, with ten obsolete 

 striae on each whirl.

 Linnaeus has not given any reference, or made any addition to 

 the above short description, so that this must probably re- 

 main a doubtful species. Schroeter and Gmelin under this 

 name have described a shell, which they say varies from two 

 and a half to four inches in length, with about twenty-four 

 whirls, white variegated with yellowish brown or chestnut, 

 and intermediate between T. Terebra and T. variegatus. 

 Dr. Pulteney considered the former of these shells to be the 

 Linnsean T. ungulinus, and Montagu has conjectured that 

 they may be only Varieties of the same species. 



TEREBELLUM. 138. Shell turrctcd, umbilicated^ 

 glabrous, and yellowish, with a keel on each 

 whirl.
