XX APPBNDIX. 



1791. STROMBUS RUGOSUS. 



S. tests, oblong^, longitudinaliter plicata, transversa 

 striatd, apice acuminata, anfractibus siiperne no- 

 dulosis ; ultimo anfractu altera tuberculorum mini- 

 morum serie instructo; apertur^ oblonga, labio 

 externo intus striate, columellari valido, superne 

 infraque transversim striate ; sutura crenulata : 

 long. 1-j?^ lat. -5%. unc. 



Obs. This sliell approaches nearer to S. plicatus 

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

 distinguished by the second row of tubercles on the 

 last volution, by its longer spire, and by its rugosity. 

 Tlie specimens are of a rusty brown colour, a little 

 mottled with white. From the East Indies. 



1792. STROMBUS GRACILIOR. 



S. testa ovato-oblongS, apice acuminato-pyramidali, 

 ad basim transverse striata, pallide aurantiacil ; 

 anfractibus superne nodulosis; labio interno te- 

 nui, expanso, externo dilatato, intus transverse 

 leviter sulcato : long. 2J-^ unc. lat. 1 ^^^ unc. 



Obs. A general resemblance is observable be- 

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

 pally distinguished 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-turgida, apice acuminata, Isevi, aibida, 

 pallide rufo-subtessellata 3 anfractibus superne se- 

 rie unic^ tuberculis subacutis coronulata, superi- 

 oribus cancellatis; varicibus duobus ad quatuor 

 rufo-maculatis J aperturi elongata, labii columel- 

 laris margine inferiore simplice ; columella basi 

 sulcata: labio externo intus deiiticulato, dentibus 

 obsoletis duobus vel tribus ad basim marginis.
