effroy Catalog V, p. 147; Cat. der Conchyl.-Samml. von Fr. Paetel, 

 8te lieferung, p. 5d9; Proc. Cal. Acad. Sci. iv, p. 201, and several 

 other places, but nowhere can I find a reference to the description. 

 It was probably never described. The form is very close to G. 

 affinis and G. reevei.

The strong keels of the upper surface separate this form from 

 allied species.

Shell orbicularly conical, moderately umbilicated, rather solid, 

 whitish, marbled with olive and pink, and with a few broad pure 

 white flames descending from the sutures and interrupted on the 

 keels with brownish red ; base reticulated with gray and minutely 

 spotted with red ; spire conical ; whurls 5, angular, with two prom- 

 inent rounded keels, one next the suture; concave between the 

 suture and upper keel, and a little concave between the keels, finely 

 spirally ridged and decussated with exceedingly fine and close 

 oblique longitudinal lines; base convex, finely concentrically I'idged 

 and decussated like the whorls, the ridges increasing in size toward 

 the umbilicus. (Angas.) Alt. 8, diam. 10 mill.
