folds in the middle. Peristome whitish, thickened, expanded, 

 nearly continuous, with the margins approaching and joined 

 by a callous. Length 10, diam. 3 mm. (Bgt.).

Bourguignat notes that it differs from P. polyodon by the 

 longer, fusiform and not ventricose shell, the deeper umbilical 

 crevice and larger perforation ; by the compression of the base 

 of the last whorl, where there is a projecting ridge nearly as 

 acute as in P. goniostoma; finally by the different and less 

 numerous apertural teeth. 



24. ABIDA CATALONICA (Bofill). Palatal plicae long, as in 

 P. affinis, but possessing a stronger parietal, and especially 

 two subhorizontal columellars, of which the upper one emerges 

 to the peristome. Length 11, diam. 2y 2 . 



Spain: Camprodon, in the Pyrenees of prov. Gerona; also 

 at "Den Montegut," Eibas valley; Olote (Bofill).

25. ABIDA HETAERA (West.). Shell perforate-rimate, cylin- 

 dric, at the apex conic, densely and regularly, delicately but 

 sharply striate, more distinctly and strongly so on the last 

 whorl; fulvous-corneous. Whorls 10, very slightly convex, 

 regularly increasing. Aperture oval, margins not connected 

 or but very delicately so. Angular fold doubled in front, one 

 parietal fold slighter, immersed ; two columellar lamellae (the 

 first very long, submarginal, the second shorter, not mar- 

 ginal) ; four palatal laminae (first very deeply placed, second 

 and third very long, submarginal, penetrating inward to the 

 columellar margin, as seen in a front view, fourth wholly 

 basal; the second and third opposite the columellar lamella 

 and parietal plica) ; sometimes having a tubercle in the angle 

 between columella and parietal wall. Length 8, diam. 2.33 

 mm. (Pupa (Torquilla) hetaera Westerlund, Verh. zool.-bot.
