1791. STROMBUS RUGOSUS. 



S. tcstft obloncil, longitudinaliter plicata, transverse 

 striata, apice acuuiinata, anfractibus siipernfe 110- 

 dulosis; ultimo antVactu altera tuberculorum mini- 

 luorum serie instructo ; apertura oblon^ft, labio 

 externo iiittis striate, columellari valido, superne 

 infraque transversini striato ; suturil crcnulata : 

 Ion:;. l-,% lat. -,\ unr. 



Obs. This shell approaches nearer to S. plicatus 

 than to any other species; from that it is, however, 

 distiiifT'iished by the second row of tubercles on the 

 last volution, by its longer spire, and by its rug;osity. 

 The specimens are of a rusty brown colour, a little 

 mottled with white. From the East Indies. 



1792. STROMBUS GRACILIOR. 



S. testa ovato-oblonga, apice acuniinato-pyramidali, 

 ad basini transverse striata, pallide aurantiacfi ; 

 anfractibus superne nodulosis ; labio interno te- 

 nui, expanso, externo dilatato, intus transvefsis 

 Icviter sulcato : long. 2^ unc. lat. 1/^ unc. 



Obs. A general resemblance is observable be- 

 tween this and Str. Pugilis, from which it is princi- 

 ])ally distiuguishcd by its smaller size, its acutely py- 

 ramidal spire, and its more slender shape. It may 

 possibly prove to be only a variety of that species. 



1823. CASSIS CORONULATA. 



C. testa ovato-turgidvi, apice acuminata, Ipevi, albida, 

 pallide rufo-subtesscllata ; anfractibus superne se- 

 rie unicd tubercnlis subacutis coronulata, superi- 

 oribus cancellatis ; varicibus duobus ad quatuor 

 rufo-macnlatis; apertura clongata, labii columel- 

 Jaris niargine inferiore simplice ; columella basi 

 suUrata: lal)io externo intus denticulato, dentibus 

 pbsoletis duobus vel tribus ad basim marginis.
