FULGUR. 139 



S. Harfordi, Stearns. 



Solid, elongate, regularly fusiform ; spire elevated, whorls six 

 or seven, moderately convex, slightly flattened (in outline) above, 

 with a groove or channel following the suture ; color chocolate- 

 brown ; surface marked by numerous narrow revolving costte, 

 which alternate in prominence on the body-whorl, and longitudi- 

 nalty by fine incremental striae, and the upper whorls by obtusel}" 

 rounded ribs of more or less prominence ; aperture ovate, about 

 half the length of the shell, polished, white and flnel}^ ribbed 

 within ; canal short, nearly straight. 



Length 2-1, lat. -94 in. 



Mendocino Co. and Farallone Is., California. 



Mr. Dall compares this species to S. ci7i7iamomea, Reeve. It 

 has not been figured and I have not seen it. Yer}^ rare.

aenus FULGUR, Montfort. 



Shell with a simple, ver^^ thin periostracum, with little raised 

 revolving lines ; pyriform, with the whorls wound tightly round 

 the axis, leaving no umbilicus, angular behind, with the upp(M- 

 surface shelving towards the angle ; and the wdiorls below the 

 angle ventricose, and thence gradually contracted and terminating 

 in a moderately elongated canal, generally little or no longer 

 than the aperture, concurrent with and proximal to the siphonal 

 fasciole, and correspondingly tortuous. Siphonal fasciole coinci- 

 dent with the columellar plait ; spire variable in evolution, witli 

 a papillary nucleus ; sutures plane ; aperture rhombo-ovate ; outer 

 lip in youth striated within; columella covered with a thin, 

 callous coat, decidedly and regularly concave, and with a wide 

 oblique marginal fold. Operculum with the nucleus apical. 



Animal rather small, retractile with its operculum within the 

 shell for about a third of a volution from the aperture. 



I quote above Prof. Theodore Gill's somewhat length}^ des- 

 cription, forming part of his admirable synoi)sis of the genus; 

 which I have adopted as a basis for this work. The distribution 

 of the genus is restricted to the temperate and subtropical waters 

 of the Atlantic Coast of the United States, and its manifest oon- 

 chological position connects Fasciolaria with Neptunea. It is 

 not infrequent in our mipcene deposits, from wliicli several 

 species have been described l\y Mr. Conrad.
