the others in the right and left angles), two columellar lamel- 

 lae (the upper horizontal, long; second obliquely ascending, 

 short). Three plicae, the basal one tooth-like. Margins sep- 

 arated (or very weakly united) ; outer margin more strongly 

 arcuate above. Length 4-5, diam. 2-2% mm. ( Westerlund) . 



Basses-Pyrenees : Banks of the Adour and le Gave de Bay- 

 onne, Orthez ; woods behind the chateau de Cassaber a Caresse 

 (Dupuy) ; on nummulitic limestone scarps between le Moulin 

 d'Esbone et le Boucau (Folin) ; Garonne valley in Haute - 

 Garonne (Fagot).

This form, which I have not seen, appears from the accounts 

 to be closely related to ringens, perhaps a subspecies thereof. 

 The original description and figure are inaccessible to me, and 

 de Folin 's woodcut is obviously too crude to be worth repro- 

 duction here. 



Var. garumnica Fagot. Shell larger, less acuminate, with 

 the upper palatal plica longer and prominent. This variety, 

 which seems characteristic of the Garonne valley, appears at 

 Luchon and lives from there to Montpezat on the left bank of 

 the Garonne. On the right bank it attains nearly to the limit 

 of the Eocene at Mauran. It is often found in the debris of 

 the Garonne at Toulouse (Fagot) . Westerlund adds that the 

 peristome is more expanded than in baillensi, and the parietal 

 wall more strongly plicate. Length 6%, diam. 2% mm. 



Series of A. affinis. 



Rather small and slender forms, much like the braunii group 

 in apertural structure. Pyrenean center. 



Caziot and Margier's groups of pyrenearia and affinis, Wes- 

 terlund 's groups 4, 5, 6, contain species of the eastern Pyre- 

 nees, chiefly in the dep. Pyrenees-Orientales in France, and
