 Inhabits the coasts of Jamaica. Linnaus. West Indies. Mar- 

 tini. Florida, Humphreys. 

 Shell about three inches and a half long, and two inches broad, 

 generally of a pale red or flesh-colour, but is sometimes 

 brown, and marked with a paler band round the row of spines 

 on the shoulder of the body-whirl ; the row of spines on the 

 spire becomes gradually smaller, and the upper whirls are 

 strongly striated transversely ; the aperture is highly polished, 

 and the outer lip is more or less distinctly striated within. 

 Dr. Leach, in the Zoological Miscellany, t. 22, under the 

 name of Strombus Sloanii, has figured what may probably 

 be a Lusus of S'. Pugilis, with elevated compressed quadrate 

 processes round the upper end of the body-whirl, and at all 

 events it appears by the aperture that the shell has not suffi- 

 ciently attained its full growth to warrant its introduction as 

 a species, till some more mature specimen has been found. 



MARGINATUS. 18. Shell transversely keeled, slightl}^ 

 nodulous, and both the lips pointed above ; 

 outer lip with a broad thickened margin.

Inhabits the coasts of China. Humph? ej/s. 



Schroeter, Gmelin and Chemnitz appear to have mistaken 

 5. accinctus for this species, and a shell which Mr. Hum- 

 phreys sold me, under the name of S. marginatus, answers 

 better to the Linnaean definition ; it is about sixteen lines 

 long, and half as broad, and the spire occupies about two- 

 fifths of the length ; the colour is pale chestnut or fawn- 

 colour, slightly mottled with white, and the margin of the 

 aperture and die pillar are white ; both the lips are much 

 thickened, and their pointed terminations are attached to the 

 second whirl of the spire ; the aperture is yellow.
