section shows Vt the outer margin is thin and sharp, and that the 

 aperture is most proball/ not rhomboidal but transversely elliptical, the 

 outer angle acute and the inner probably narrowly rounded. The form 

 is thus like that of P. lapicida (Salter), differing therefrom in being 

 larger and in having a wider umbilicus ; the whorls abo are not so flat 

 above, and not SD onvex below.

PL'EUROTOMARIA HYALE. (N. sp.) 



Description. Shell rather small, lenticular ; spire depressed convex, 

 the whorls slightly elevated above each other at the suture, flat or with a 

 barely perceptible convexity on the upper side ; base a little more strongly 

 convex than the spire. Umbilicus either very narrow or completely closed. 

 Surface unknown. 



Width about 9 lines ; height 4 to 6 lines. 



The character of the margin has not been clearly ascertained, but it 

 appears to be acute, ard probably has a very narrow band on the edge. 

 The shape may be desci'bed as V3nhi 301 e -lenticular, both spire and base 

 moderately convex, and the peripheral edge being at about the mid-height, 

 or a little above. It resembles P. Progne, G-eol. Can., p. 181, f. 176, 

 but is a smaller species, and has t*ie ^Inrls slightly elevated above each 

 other at the suture 3.
