P. ornrENTALIS A. Adams. PI. 2, fig. 16. 
Shell ovate-rounded, subinvolute, white, solid, shining ; no spire; 
aperture large, spreading in front; lip semicircular, the upper 
angle produced and rounded. (Ad.). 
This species has somewhat the form of P. aperta, but wants the 
transverse impressed groove seen in that species; the plates of the 
gizzard, moreover, are produced at each end into long, slender pro- 
cesses, somewhat similar to those of P. schreteri, the shell of which 
is very different in form. (Ad.).

P. anaast Crosse & Fischer. PI. 3, figs. 59 (type), 57, 58. 
Shell oblong, longitudinally very delicately wrinkle-striate, thin, 
pellucid, shining, hyaline-milky ; apex rounded, a little concave in 
the middle; convex outside, subcylindrical, spirally convoluted 
within. Aperture very ample at base, the outer margin semicircu- 
lar, simple, acute, extending some above the apex. Interior covered 
with a white, pellucid, very thin callus in adults. Alt. 30, diam. 20 
mill. Stomach plates very solid, looking like a cocked hat. (C. & 
F.).

This species has repeatedly been declared identical with P. aperta, 
but it seems to have the lip less angular above than usual in that 
species, and the stomach-plates are probably different, judging from 
the brief remark of C. & F. to the effect that they are very solid 
“et affectent l’apparence d’un chapeau a cornes.” One would 
hardly say this of the plates of P. aperta (pl. 9, f. 1, 2, 38, 6, 7). At
