300 ABIDA. 



very distinct by the numerous teeth and folds which are in 

 the aperture, has similarity of form with Pupa polyodon, but 

 it is shorter and more ventricose; the aperture is subtrian- 

 gular, and the labrum, or lateral border, is ornamented with 

 four laminae which become lost in the cavity. Two teeth are 

 placed on the columellar margin, and two other lamellae cover 

 the columella [i. e., the parietal wall] ; one of these lamellae, 

 placed further forward, abuts on the upper angle of the aper- 

 ture at the point of insertion of the lateral margin with the 

 columellar. The whole surface is very distinctly and obliquely 

 grooved, the grooves visible under the lens, and sometimes to 

 the naked eye. The Tyrol. (Pup[a] curt a Potiez et MICH- 

 AUD, Galerie des Moll., Donai, i, 1838, p. 164, pi. 16, f. 13-14.) 

 The figure shows a shell 9y 2 mm. long, of about 9 whorls. It 

 does not seem to have been recognized by subsequent authors, 

 and its position is dubious. Possibly a Chondrwa. 



Var. subcylindrica Locard, 7-Sy 2 mm. long, subcylindric. 

 Mont-d'Or lyonnais and debris of the Rhone north of Lyons. 



Var. ventricosa Loc. Smaller than the type, shorter, more 

 conic and more swollen at the base ; special to the environs of 

 Lyons. 



Var. bugeysiaca Loc. Of medium size, a little ventricose, 

 the peristome quite strongly reflected, columellar and palatal 

 folds deeply immersed except the third palatal. Found at 

 Thoys near Belley, department de 1'Ain. 



Form intrans Westerlund (Syn. Moll. Extramar. Reg. Pal., 

 1897, p. 80) has the second, third and fourth palatal plicae 

 prolonged inward as far as the columellar margin (as viewed 

 from in front) . Lyons. In typical frumentum only the third 

 or lower palatal plica is so long. 



Var. turgida Parr. Kiister. PI. 42, fig. 6. Very small, 

 strongly ventricose, the folds strongly developed. Alt. 2%-3, 

 diam. 1% lines. In Switzerland, Carniola, in Istria near 

 Trieste, in company with the typical form. Pupa frumentum 

 var. curta (Pupa turgida Parreiss Ms.) KUESTER, Conchyl. 

 Cab., Pupa, p. 41, pi. 5, f. 20, 21. Probably not a valid race, 

 as such short forms occur as individual variations in normal 

 colonies. It is not Pupa curta Pot. et Mich., 1838.
