Stephanoconus vaughani (Dall, 1916)

 

 

Description (2):

 

Shell of moderate size, solid, conic, with about 11 whorls excluding the (defective) nucleus; the spire is moderately elevated, wavy-nodulous at the shoulder, with a very narrow but sharply cut suture; between the shoulder and the edge of the suture are three distinct spiral threads with somewhat wider interspaces ; the sculpture of the sides of the shell, for at least half the length of it, is composed of spiral rows of low pustules apparently  eated on obscure flattish spiral threads. The remainder of the sides, the aperture, and the canal are obscured by matrix (2).

Height of shell, about 47 ; diameter at shoulder, 23 ; height of spire about 7 mm.

 

Locality.—Station 7074, at Hale landing on the west bank of Flint River, 7 miles southeast of Bainbridge, Decatur County, Georgia, in coralliferous hert; Vaughan, Cooke, and Mansfield, 1914. U. S. Nat. Mus. Cat. No. 166720 (2).

 

This species recalls Conus consobrinus Sowerby, of the Santo Domingo Oligocene, but the granulation is not on elevated zones and the spire is lower and less conspicuous, judging from the insufficient description of this unfigured species, which is united by some authors with the C. granozonatus of Guppy (2).
