Pynda arxiana^ Reeve, (not Linn.) Conch. Icon. pi. 5, fig. 10. 

 This species inhabits the Atlantic coast from Georgia to Massachusetts. 

 Reeve, when he published his monograph of Pyrula, in 1847, was unacquainted 

 with the habitat of this common and long known shell. There is a distinct 

 variety of this species on the southern coast, with much shorter and thinner 

 spines, and it is also longer and thinner than the typical form,

 living specimens may be obtained 12 inches in length.

F. candelabrum. (Pyrz^/a, Lam.) 



Kiener, pi. 8, fig. 2. 

 Kiener and Reeve suggest that this shell is a variety of Fulgur perversum. It 

 does not appear that more than one specimen has been discovered. 



F. GiBBosL'M. Pyriform, ventricose, thick, armed with broad prominent 

 foliated thick spines; shoulder carinated ; spire short, the four upper whorls 

 tuberculated on the upper margin of the suture; columella sinuous ; middle of 

 the beak profoundly tumid, on which elevation are robust alternated wrinkled 

 stride ; labrum channelled below, corresponding to the external hump; margin of 

 labrum very sinuous towards the base, the interior with slightly raised lines, 

 and of a yellowish orange color ; color white, with long purplish lines and a 

 broad indistinct revolving white band on the body whorl. 



PyruJa 'perversa, var. Kiener, pi. 9, fig. 2. 



The revolving lines are obsolete on the upper part of the body whorl, and 

 there are revolving wrinkled slightly raised lines on the spire. 



A specimen of this species is in the collection of the Academy, and Kiener's 

 figure has a close resemblance to it. It is not known to inhabit the coast of the 

 United States, and is probably from Campeachy Bay. 



This shell is not a variety of F. ferversum, as Kiener supposes, but if not a 

 distinct species, must be a sinistral variety of F. carica. That shell, however, 

 is common on the coast of the United States, but a sinistral specimen is there 

 unknown.
