numerous spiral threads and fine axial ribs; the penultimate 

 whorl carrying twelve nodes on the angulation ; suture distinct,

 above the middle, concave above, convex below, marked in 

 front of the angle with numerous raised spiral ridges with 

 wider interspaces carrying small intercalary threads.

Genus DRILLIA Gray 



Drillia ochsneri, new species 



Plate 6, figures 9a, 9b, and 9c. 



Shell large, fusiform, with high spire and acute apex ; whorls 

 eight or nine, angulated a little below the middle, concave 

 above, flat or convex below, crossed by ten or eleven low axial 

 ridges most prominent on the shoulders where they form nodes, 

 but disappearing above the shoulder on the whorls of the spire 

 and on the anterior portion of the body-whorl ; spiral sculpture 

 consisting of revolving threads which occur only on the an- 

 terior portion of each whorl ; nodes obsolete on the body-whorl 

 of some specimens ; suture distinct ; aperture narrowly ellip- 

 tical, with a deep posterior sinus betvv^een the shoulder and the 

 suture; columella smooth and twisted; canal moderately short 

 and curved. 



Dimensions : — Altitude of the type specimen, 43 mm. ; diam- 

 eter of the last whorl, 20 mm. ; length of the aperture including 

 the canal, 22 mm. 



Type: — No. 215, and cotypes Nos. 216, 217, Cal. Acad. Sci., 

 lower Miocene of Kern River, California, locality 65, on the 

 west bank of a small canyon 1^/4 miles northeast of Barker's 

 ranch house. 



This species has been referred to in a few cases as Drillia 

 johnsoni Arnold. It differs from the latter in the following 

 respects : angulation of the whorls more anterior, nodes and
