122 PALAEONTOLOGY OF CALIFORNIA. 



CONUS, Linn. 

 C. Remondii. 



' PI. 20, fig. 79. 



( VolutUithes Califomica, Con. Pacific R. R. Report, vol. 5, p. 322, PI. 2, Fig. 9.) 



Shell biconical; spire nearly a third of the total length; 

 whorls six, sloping above, crenulated on the angle; sides straight, 

 regularly conical. Aperture linear, biangular behind, a little 

 narrowed in advance. Surface marked by numerous revolving, 

 impressed lines, and by fainter lines of growth. 



Length, usually about 1 inch. 



Localities: Found by Mr. Remond at Cochran's, east of Mount Diablo, and 

 since found at Bull's Head Point, northeast of Martinez; at Clayton, above 

 the coal ; and at San Diego (Division B.). Also near Canada, or "Cajon de las 

 Uvas," Los Angeles County, whenc*e it was described by Mr. Conrad under the 

 above name. 



This shell resembles C. Rouaultii, d'Arc., of the French Eocene: see Mem. Soc. 

 Geol. de France, 2 ser., torn. 3, pi. 13, fig. 22. It tapers more regularly anteriorly, 

 and the surface-markings are less distinct ; it is also more robust. The specific 

 name CalifoTnicus having been used by Hinds for a recent species, I propose the 

 above name in honor of Mr. Remond, who discovered the specimens from whicli 

 I became acquainted with the species. 



G. Hornii, n. s.

 a half or eight, concave above, acute on the angle, with a very 

 tine thread-like groove just inside of the margin. Mouth long,

 sides of the body whorl straight. Surface marked by a few 

 oblique, revolving bands below, and sometimes by one or two 

 on the top of the whorl.

 Horn.
