FULGUR. 141 



lum ovate, thick, with a broad callus around the inner edge, 

 which is heaviest on the left side; outer surface coarse and rough, 

 greenish yellow. Mr. Conrad adopts Linnaeus' name, Aruanum, 

 for this species, and st^s that the figures in llumphius and 

 Gnaltieri referred to by him represent this species : the latter 

 does, but the former is Fumta proboscidtferus, Lam. I am com- 

 pelled on account of this uncertainty to reject the prior name 

 given by Linnaeus in favor of carica under which the species is 

 more generally known.

On the coasts of Georgia and Florida occurs a variety which, 

 commencing like a normal carica, eventually becomes more 

 thickened, the spines fewer in number and more prominent, the 

 columella white The appearance of fine specimens is perhaps 

 sufficiently distinct to justify its separation as a different species. 

 The ordinary manifestation of carica occurs in the same regions, 

 and various transition states as well. The coloration of the rest- 

 periods is more vivid and is retained to a much larger size in the 

 Southern than in the Northern specimens. An exaggerated 

 specimen of the var. cHrtwiitt is the shell called by Lamarck 

 Pyrula candelabrum (fig. 389) in which the animal has completed 

 the growth of the body-whorl in three growths, and consequent!}', 

 has only three spines upon this whorl. The type (and only 

 specimen known) formed part of the Lamarckian collection. F. 

 Kieneri, Phil. (fig. 390), is founded on a reversed and distorted 

 shell of var. elicvans. Specimens of this distorted form, uni- 

 formly from the Southern Coast, are not uncommon, and are 

 either dextral or sinistral. Conrad has named sinistral specimens 

 of this variety Busy con yibbofsum. Sowerb}^ in his recently pub- 

 lished monograph of FHXHX (Thesaurus Conchyliorum) describes 

 and figures a F. lainellomix, Kay (meaning De Kay, or of Gould, 

 in his plate-explanations), said to come from the Northwest 

 Coast of Africa. Neither of the authors cited described such a 

 species, and the figure represents a young, but beach-worn, F. 

 carica.

The spire is very low and the tubercles numerous and small. 

 The shell is usualty reversed, but sometimes dextral, and is
