Miocene. 

 Cancellaria dalliana n. sp. 



Pl.\te XV, Figs. 39-42. 



Shell of moderate size, fusiform; spire high and angular; whorls angular 

 and spinose; columella thickly crusted within in old specimens; surface 

 marked with strong varical ridges and lines, the ridges rising in thin edges 

 on the upper surface of the body whorl. The lower part of the body 

 whorl is ornamented with strong revolving lines with wide interspaces in 

 which there are usually 1-3 secondary lines. The canal notch is not shown. 



Occurrence. — This species occurs with the succeeding in 

 the Lower Miocene beds of Barker's ranch, on Kern River. 



Cancellaria pacifica n. sp. 



Plate XV, Figs. 43-45. 



Shell moderate in size, %-\yz inches in length, width Yz as great; spire 

 moderately elevated; mouth oval in outline; whorls angulated, bearing 

 small nodes on the upper angles; surface ornamented with revolving lines, 

 heavier and lighter lines occurring alternately on the body whorl, crossed by 

 vertical ridges. 



This shell seems to be somewhat closely related to 

 C. granosa Sowerby, described from Van Dieman's Land. 



Occ2irreiice, — This shell occurs with the preceding species 

 in the Lower Miocene beds of Kern River. 



Cancellaria joaquinensis n. sp. 



Plate X\^ Figs. 46-48. 



Shell of moderate size, stout, and ovate; i inch or more in length and 

 nearly as broad; spire medium or low, sloping evenly without conspicuous 

 angles; shell thick; inner lip crusted; surface ornamented chiefly by revolv- 

 ing lines and interspaces, with finer secondary lines within; varical ridges 

 weak, but forming on the upper angle of the body whorl a single circle of 

 nodes. 



This species is related only distantly to any other described 

 form occurring on the Pacitic Coast. 



Occurrence. — Lower Miocene beds of Kern River, where 

 four or more well preserved specimens were obtained.
