Description. Shell rather small, slender, fusiform, of about six gently 

 convex, or nearly flat whorls ; apical angle 35. Surface unknown. 



The only specimen collected is a cast of the interior. Length 19 lines ; 

 length of the body whorl, measured along the inner side of the aperture 

 from the suture to the lower angle of the aperture, 11 lines ; greatest 

 diameter, near the upper edge of the body whorl, 5J lines. 



Locality and Formation. L, Point Rich, Newfoundland.

 209. P. virguncula, 



Description. Shell small, turbinate ; spire evenly pyramidal ; apical 

 angle about 80 ; whorls about four ; the last one strongly ventricose. 

 Along the middle of the last whorl there is a concave spiral band, and, 

 separated from this by a narrow thread-like ridge, a deep groove ; above 

 which, flat or very slightly concave to the suture. In the upper whorls 

 the band gradually becomes concealed in the suture, the groove remaining 

 distinct. The base below the band is moderately convex, except on ap- 

 proaching the aperture, where it is strongly so. Aperture rhomboidal, 

 obtusely angular at the band ; the upper half of the inner side formed by 

 the penultimate whorl ; the lower half by a thickened slightly effuse lip. 

 Umbilicus minute, but visible. Surface with fine backward curving striae. 

 Length 7 lines ; width 6 lines. 



Smaller than P. selecta, the band concave instead of convex, and with 

 a groove above it.
