REPORT OF THE STATE PALEONTOLOGIST I903 293 



Differs from S. asperostriatus Billings in its smaller 

 size, its more depressed spire, its relatively narrower umbilicus, the 

 closeness of its raised striae, and the absence of any carina along the 

 underside. 



Described from three specimens collected by Mr Percy E. Ray- 

 mond. 



Genus subulites Conrad 



Subulites raymondi sp. nov.

Description. Shell small, fusiform ; apical angle about 44° ; 

 length of specimen, with apical whorl, or a little more, lost, 9.5mm; 

 greatest thickness across axis at middle of shell 3.4mm. Whorls 

 five or six; penultimate whorl showing a rapid elongation, body 

 whorl 6mm long or considerably longer than the spire. 



Aperture elongate, oblique, narrow, with well formed anterior 

 crnal; inner wall of aperture nearly straight; outer lip convex, 

 gradually increasing its distance from the axis for about one fourth 

 its length, remaining very nearly parallel for another fourth and 

 then slightly increasing its convexity to anterior extremity. With 

 aperture toward the observer, the shell appears slightly angulated 

 at a little above middle on the left, and a short distance below the 

 middle on the right; turned tow^ard the left through 90°, the right 

 hand outline is more uniformly convex. Suture but slightly im- 

 pressed ; surface smooth. 



Observations. The shell surface is well preserved and in some 

 lights seems to show growth lines much like those of T e r e b e 1 - 

 lum subulatum Lam., to which this species shows a super- 

 ficial resemblance in its spire, inner wall of aperture, and anterior 

 canal. With other lighting however there seem to be growth lines 

 running gently backward from the suture. These lines are not 

 easily seen and some of them may be due to marks made in cleaning 

 the specimen. Still very faint but more easily seen are some ex- 

 tremely narrow, fine, raised, transverse striae about 4mm apart. 



This species has been named after Mr Percy E. Raymond, of the 

 Carnegie Museum, Pittsburg Pa. who found the species in material 

 from the section described.
