312 ABIDA. 



of being thin and sharp, they are broad, thick, tuberculose, as 

 though crushed down. As only three specimens were found, 



1 suspect that it may be an abnormal form. 



Var. phymata West. Very beautifully, hair-fine striate, the 

 strise stronger and more spaced on the last whorl, reddish- 

 yellow, whitish towards the aperture, the last whorl with a 

 white hump on the base ; margin thickened throughout, white- 

 lipped, narrowly reflected ; aperture with 8 lamellae and plicas : 



2 parietal, 2 columellar, 4 palatal (the first small, deep within, 

 second to fourth marginal, second and third elevated within, 

 obliquely truncated, beyond which they continue inward as 

 small folds). Length 7, diam. 2 mm. Hautes-Pyrenees (Pupa 

 secale var. phymata Westerlund, Fauna, iii, 1887, p. 110). 



Var. piniana Fagot. Shell minutely perforate, regularly 

 conic-elongate, horn-brown or violet, very closely striate, 

 scarcely shining. Spire lengthened, slowly increasing. Whorls 

 8, scarcely convex, regularly increasing, the last larger, some- 

 what compressed around the umbilicus. Aperture oblique, 

 truncate-oblong, with 8 lamella and folds: 2 parietal, 2 colu- 

 mellar, the upper nearly marginal, lower immersed, 4 palatal 

 plicae, the first very small, very deep within, second marginal, 

 third somewhat and fourth more immersed. Peristome acute, 

 margins separated, the outer expanded, columellar reflected. 

 Length 7, diam. 2*4 mm. ( Westerlund). France: Ponech 

 (Ariege). Pupa piniana Fagot, Bull. Soc. Agr., Sc. et Litt.

Abida secale boileausiana ('Charp.' Kuster). PL 46, fig. 11. 



A species of the group of P. frumentum. The shell is ob- 

 liquely rimate, subperforate, somewhat lengthened conic, 

 finely and obliquely rib-striate, satin-shining, light corneous- 

 yellow. The spire is somewhat fusiform, apex obtuse, the 9 

 or 10 whorls narrow, very slowly increasing, weakly convex, 

 united by a simple, little-impressed suture, the last whorl con- 

 tracting, weakly compressed below, the base rounded. The 

 aperture is lengthened, rounded, yellowish flesh-colored, with 

 8 snow-white folds, of which three are on the parietal wall, 

 the first and largest arising from the insertion of the peri- 

 stome, the second deep within, the third near the angle formed 

 by the parietal wall and columella. On the columella there 

 are three folds, and in the palate three, the upper one largest 

 and emerging to the edge of the lip ; above it the beginning
