1585 Scaphella (Voluta) Amheimi 



"Shell regularly formed, elongate-ovate; body whorl more 

 than 2-3ds as long as the spire; the spire an inch long, and made 

 up of 6 whorls, the terminal nucleus being very small, pointed and 

 oblique, which latter character places this species in the section 

 Scaphella of Dall. Ground color obscure yellow, covered by a 

 layer of chalk-like deposit. The body whorl has some coarse 

 longitudinal elevations and depressions, remnants of former lip 

 extensions, and there are 2 large patches of dark rusty red at a 

 wide interval which do not appear to form an interrupted band. 

 The aperture is elegantly formed and measures 1 % inches long 

 by % inch wide. The inner lip is regularly outlined on the colu- 

 mella; columellar plaits 4, sharply oblique, the last one strongest, 

 forming a prominent ridge parallel to the canal. The upper out- 

 lines of the mouth meet in a sharp angle, but the base has a 

 well denned bifurcation. The whole of the aperture and the edge 

 of the outer lip are heavily coated with enamel of a yellowish tint, 

 and rust stained. Size 3 % inches long, and 1 y 8 inches wide. Ani- 

 mal without operculum." — J. J. Rivers, Nautilus 5:111. 



Type locality: — Monterey bay, Cal. (dredged).

"Shell small, globose turbinate, narrowly but distinctly and 

 deeply umbilicated. Spire low-conic, acute; whorls 4, slightly 

 shouldered below the sutures, the upper-lateral portion rather 

 flattened, periphery and base convex. Surface smooth, horn-col- 

 ored. Aperture oblique, ovate, angled above, broadly rounded 

 below; upper portion of the inner lip adherent to the body whorl, 

 lower portion arcuate, without a callus thickening. Alt. 3, diam. 

 2.5 mm." — Pilsbry, Nautilus 5:143.
