114 PALAEONTOLOGY OF CALIFORNIA. 



The anterior end of the figure is restored from the back of a 

 cast. The first two or three whorls are very small, and the angle 

 of the surface is much greater than that of the subsequent volu- 

 tions. 



Figure, natural size. 



Locality : Three specimens were found on the north fork of Cottonwood Creek, 

 Shasta County, by Mr. Re'mond. 



A. Californica, n. s. 



PL 19, Fig. 68. 



Shell large, ovate; spire elevated; whorls six or seven, rounded, 

 somewhat flattened in the middle ; suture distinct. Aperture 

 moderate, acute behind, rounded in advance. Surface smooth, 

 marked by faint, sinuous lines of growth, which show that the 

 outer lip retreated gradually above, and was most prominent in 

 the middle. 



Figure, a restoration ; about natural size. 



Half a dozen specimens have been found northeast of Martinez (in Division 

 A.), and in beds of the same age, about two miles north of Benicia, and a single 

 specimen was found eight miles north of Yreka. The substance of the shell is 

 thick, and in all the specimens is so crystalline that not a specimen has been found 

 sufficiently perfect to be drawn. 



GLOBICONCHA, D'Orb. 



G. (Phasianella ?) Eemondii, n. s. 



PL 19, Fig. 69. 



Shell subglobose, spire elevated, conical ; whorls about five or 

 six, convex. Aperture broad, acute behind, rapidly widening, 

 and regularly rounded in advance. Surface ? 



Figure, natural size. A restoration from a cast, showing crystalline fragments 

 of the shell, but none of the surface. 



Locality: About two miles north of Benicia (in Division A.). A single speci- 

 men, found by Mr. Remond.
