TURRIS LINCOLNENSIS n. Sp. 



Plate VII, Figure 24 



Description Shell small; spire elevated; whorls six in number; each whorl is 

 characterized by a very pronounced angle situated at about one-third the distance 

 of the length of the whorl below the suture; the angle between the upper and lower 

 surface of each whorl is approximately 110. The surface above the angle is very 

 slightly concave; below the angle it is straight to very slightly convex; suture 

 greatly impressed. Surface of whorls is ornamented with numerous very fine re- 

 volving striae ; longitudinal ornamentation is absent except for fine lines of growth ; 

 aperture roughly trigonal in outline; outer lip with a sharp angle at its junction 

 with the shoulder of whorl; canal short with a very slight notch at its anterior 

 end; outer lip thin; inner lip with very slight callous. 



Dimensions Altitude of shell 16 mm.; altitude of spire 5.5 mm.; maximum 

 diameter of shell 9 mm.; angle of spire 53. 



Occurrence At locality 352 (University of Washington Paleontological Col- 

 lection) in railroad cuts of the O.-W. R. R. & N. Co., one- fourth mile west of 

 Lincoln Creek Station in Section 27, Township 15 North, Range 3 West. 



Horizon Lower Oligocene; Molopophorous lincolnensis Zone. 



GENUS CONUS LINNAEUS 

 CONUS WASHINGTONENSIS 11. Sp. 



Plate VII, Figure 9 



Description Shell minute; spire high, averaging between two-thirds and three- 

 fourths of the length of the body whorl; whorls seven to seven and a half in num- 

 ber; suture linear and appressed; on the middle of the surface of each whorl, just 

 above the shoulder, there is a revolving groove; between the groove and the suture 

 there is a convex revolving fold. Ornamentation of the shell consists of very faintly 

 developed flat topped revolving ribs with interspaces of equal width; outer lip thin; 

 inner lip without callous; aperture narrow. 



This species differs from Conus ruckmani Dickerson, in the constancy of the 

 greater length of the spire and in the entire absence on all specimens of nodes on 

 the shoulder of the whorls. 



Dimensions Altitude of shell 3.5 mm.; altitude of spire 1 mm.; maximum diam- 

 eter of shell 2 mm.; angle of spire 60. 



Occurrence At locality 330 (University of Washington Paleontological Col- 

 lection) situated at the Greece ranch, four miles east of Vader, on the east bank of 

 Cowlitz River, in Section 25. Township 11 North, Range 2 West. 



Horizon Lower Oligocene; lower phase of Molopophorous lincolnensis Zone.
