Shell small, subglobose, perforate in the young slate, when adult 

 imperforate, of a rose-madder color; whorls 41. the apical one whit- 

 ish, the rest convex, and finely spirally striated, also marked with 

 faint oblique lines of growth ; suture rather deep; last whorl ob- 

 liquely descending near the lip, somewhat flattened beneath near 

 the center; aperture obliquely subcircular, iridescent within ; colu-

Shell small, very solid, orbicular, depressed, with conic spire; 

 whorls 4:1-0, convex, strongly spirally 1 irate, the line smooth, about 

 twelve in number on body-whorl, three on penultimate whorl, not per- 

 ceptibly crenulated by the very subtle incremental stria. 4 ; above the 

 line are coarse, smooth, and generally irregularly spaced, interstices 

 smooth, as wide or wider than the ribs: below more finely lirate ; last 

 whorl well rounded, deflected anteriorly ; aperture somewhat con- 

 tracted, oblique, pearly white within, peristome rather thick, its ends 

 not converging, columella short, slightly arcuate, thick and heavy, 

 terminating below in an obtuse tubercle, base of aperture some- 

 times bearing an inconspicuous dentiform callus at margin; color 

 deep crimson. Alt. 6, diam. 7 mill. 



f Mediterranean and Adriatic Seas. 



The species has also been dredged off the Atlantic Coast of France*. 



Operculum (pi. 60, figs. 54, 55) inside slightly convex, light yel- 

 low, with about ten very slowly and regularly increasing whorls, 

 the last third of the outermost considerably widened; outside 

 calcareous, white, flat, concave in the central area and coarsely ru- 

 gose, outer margins with a slightly elevated very finely radiately 

 wrinkled concentric rib, whicli is slightly more elevated near its ter- 

 mination. 



The synonyms are T. piu-jmreus Risso, T. cocdneus Miihlf., and 

 T. bellnr! P : ,yr. 



The differential characters of L. Garpenteri, L. Bctnguinea and L. 



sangcD'f'.H*!* are pointed out under the descriptions of the first and last 

 species. There is not the slightest occasion for any longer confound- 

 ing these three unfortunate species. The occurence of the real L. 

 ^sanguined Linn, in Japanese waters still requires confirmation.
