P. ORIENTALIS 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. schrceteri, the shell of which 

 is very different in form. (Ad.*).

P. ANGASI Crosse & Fischer. PL 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 1'apparence d'un chapeau a cornes." One would 

 hardly say this of the plates of P. aperta (pi. 9, f. 1, 2, 3, 6, 7). At
