short; surface ornamented by strong spiral and longitudinal lines, giving a 

 cancellated sculpture. 



Occurrence. — This species occurs abundantly in the Lower 

 Miocene beds of Kern River, 



Bullia (Molopophorus) anglonana n. sp. 



Plate XVI, Figs. 74-76. 



Shell moderate in size, i inch in length, % inch in width; spire moderately 

 elevated; aperture broad, lip simple, notched above; columella crusted, 

 whorls angulated, bearing tubercular, or spinose nodes above, and on lower 

 part of body whorl; surface ornamented with lines of growth, and with 

 revolving lines, strongest on the lower portion of the body whorl. The 

 anterior notch is deep, and bordered by 2 strong folds which extend upward, 

 revolving obliquely around the columella, forming a wide canal, shown 

 only in figure 74. 



This species is somewhat related to B. striata Gabb, from 

 the Tejon Beds, but more nearly related to undescribed 

 species occurring in the so-called Oligocene Beds of Oregon. 



Occurrence. — This species occurs not rarely in the Lower 

 Miocene beds of Kern River. 



Fusus (Hemifusus) wilkesana n. sp. 



Plate XVI, Figs. 81 anu 82. 



Shell moderate in size, robust, tapering rapidly below; spire moderately 

 elevated, angulated, with tubercular nodes on the angles of the whorls; sur- 

 face strongly marked by spiral lines and longitudinal ridges, especially 

 prominent at and below the angles of the whorls; canal only moderately 

 prolonged; open; columella somewhat curved. 



This species seems to be related to, and is possibly iden- 

 tical with Fiisus corpiilentus Conrad, from the Miocene beds 

 of Astoria, Oregon; but as Conrad's figure was drawn from 

 a cast, it is not possible to establish its identity with the 

 species described here. 



Occurrence. — The Lower Miocene beds (Temblor Beds) 

 at the Kreyenhagen oil wells. Kings County.
