Conus aegilops (Anderson & Hanna, 1925)




Shell of medium size, spire high, turrited, general form biconical; sides of body whorl almost straight, marked by faint revolving striaa above, but with stronger raised threads near the base; angle of whorls, having a distinct beaded ridge, bordered below by an impressed groove at the top of body whorl; nodes or beads 24 or more in number on a complete whorl; shoulder concave above, slope rising in a collar on the preceding whorl; lines of growth almost straight, but curving gently forward. The raised beaded cord on the angle of the last whorl gives the shell somewhat the form and appearance of an acorn of the large oaks (Quercus lobata], growing at the type locality of the species; hence the name. The length of the largest specimen found is 32 mm.; diameter, 13 mm.; height of spire, when com­plete, about equal to diameter.



No. 809, Mus. Calif. Acad. Sci.; collected by Bruce G. Martin at Loc. 245, (C. A. S. Coll.), Grapevine Creek, Kern County, California. Cast of paratype,

No. 810, Mus. Calif. Acad. Sci., from Loc. 452 (U. C. Coll.) in Grapevine Canyon; Type Tejon Eocene.


This species has a general similarity to C. cowlitzensis Weaver and it is possible that Dickerson may have had one of the specimens here described when he reported that form from the type locality of the Tejon Group.
