Scaphander jugularis Conrad, 



Pl.^te XV, Figs. 56 and 57. 



Bu/la jugularis Conrad, Pac. R. R. Rept. v. 5, p. 328, pi. vii, figs. 62 

 a and b. 



Shell not large, i-i>^ inches in length, width i^ as great; contracted 

 toward the posterior end; aperture wide, ovate; inner lip crusted; whorl 

 loosely convolute, narrowing behind; surface ornamented by revolving lines 

 crossed by oblique lines of growth. The revolving lines consist of flattened 

 ridges and rounded grooves of equal width. 



Conrad's figure lacks sufficient description to make abso- 

 lute identification possible, but as the localities are contiguous 

 and the horizon practically the same, there can be little doubt 

 as to identity. 



Occurrence. — Lower Miocene beds on Kern River, a few 

 miles south of Ocoya Creek. 



Oliva calif ornica n. sp. 



Plate XV, Figs. 54 and 55. 



Shell moderate in size, i-i>^ inches long, width more than half as great, 

 ovate, narrowing below; spire low and rounded; aperture narrow, inner lip 

 somewhat crusted; columella bearing 2 principal spiral plications, with finer 

 lines both above and below; suture impressed and sharply defined on 

 adolescent and mature shells; surface marked only by lines of growth. 



Occurrence. — Lower Miocene beds of Kern River, Barker's 

 ranch, etc, 



Oliva futheyana n. sp. 



Plate XV, Fig. 53. 



Shell similar in many respects to the preceding, but narrower, and having 

 a more elevated spire, and more graceful outline. 



Occurrence. — This shell occurs with the preceding. 



Conus oweniana n. sp. 



Plate XV, Figs. 58 and 59. 



Shell small, conical; spire moderate, conical; whorls flattened, or concave 

 above; suture impressed on young shells; aperture narrow, and straight; 

 surface marked by distant, fine revolving lines.
