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

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

 greenish yellow. Mr. Conrad adopts Linuieus' name, Arunnuin, 

 for this species, and says that the figures in Rumphius and 

 Gnaltieri referred to by him represent this species : the latter 

 does, but the former is Fasnx proboscidiferus^ Lam. I am com- 

 pelled on account of tliis uncertaint}'^ to reject tlie ])rior name 

 given by Linnteus in favor of carica — under which tiie species is 

 more generally known.

On the coasts of Georgia and Florida occurs a variet}' 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 

 suflficiently distinct to justify its separation as a different species. 

 The ordinary manifestation of carica occurs in the same regions, 

 and A'arious 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. elicean.^ is the siiell called l»y Lamarck 

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

 the growth of tlie body-whorl in three growths, and consequently, 

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

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

 Kiene/ri, Pliil. (fig. 39U), is founded on a reversed and distorted 

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

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

 either dextral or sinistral. Conrad lias named sinistral specimens 

 of this variety Busycon gibbosum. Sovverby, in his recently pub- 

 lished monograph of FiOius (Tiiesaurus Conchyliorum) describes 

 and figures a F. lamello.sus, 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 I'epresents a young, but beach-worn, 7^.
