suture; canal short, wide; aperture subovate; suture appressed; sutural band on 

 the upper portion of whorl bounded below by a depression; the sutural sinus, 

 formed by the lines of growth, makes at the lower margin of the sutural band a 

 /eentrant curve at an angle of approximately 50 ; whorls decorated by seven 

 revolving lines, with 19 on the body whorl ; the spiral lines are crossed by 12 or 

 13 longitudinal ribs which follow the curves of the growth lines, these ribs con- 

 tinue over the length of the whorls of the spire but are only slightly developed 

 on the body whorl, becoming obsolete on the lower region of that whorl. 



The sculpture of this shell is more like that of some of the recent West 

 Coast species which Dr. Uall calls Moniliopsis than like that of the Eocene type 

 Pleurotoma elaborate Conrad which is beautifully and profoundly cancellated. In 

 shape, position of the sinus of the longitudinal striae, and the character of the 

 aperture and canal, fryei has the characteristics of typical Moniliopsis. 



Named in honor of Dr. T. C. Frye of the Botanical Department of the Uni- 

 versity of Washington. 



Dimensions. Altitude 7.5 mm. ; width of body whorl 2 mm. 



Occurrence. At locality 329 (University of Washington Palaeontological 

 Collection), at bend in the Cowlitz River, near Vader, Lewis County, Section 28, 

 Township 1 1 North, Range 2 West.

Description. Shell of medium size, biconical ; whorls four to five with three 

 to four smooth, apical whorls which are very pointed; suture appressed; area 

 between the suture and the shoulder of the whorls concave and sculptured with 

 fine, curved striae ; shoulder decorated with 16 or 18 nodes ; body whorl covered 

 with revolving, microscopically, raised ribs crossed by longitudinal lines. The 

 spiral ribs or lines are better developed on the posterior region of the whorl ; 

 aperture long and narrow with parallel sides. 



This shell is close to C. remondii Gabb. Gabb states that the sides of the 

 whorls are straight and regularly conical. His illustration bears out this charac- 

 teristic. The sides of the whorls of C. vaderensis are concave. The general
