HAAS: ABIDA AND CHONDRINA. 273 



they are referable to secede or rather to A. pijrencvria. Fin- 

 ally, Pupa cadica Fag., which Pilsbry mentioned in the fol- 

 lowing of secale, I have already treated as a synonym of A. 

 partioti. 



On the Spanish side of the Pyrenees — all of the forms 

 already mentioned were described from the French side — in 

 my Estudis I could record A. secale in most of the Pyrenean 

 valleys. In the regions further south it had never been re- 

 corded, but it is before me from several localities outside of 

 the mountainous regions, along the lower course of the Ebro. 

 There it is notable that the species lives not in the valleys, 

 but on the mountains, sometimes at quite a considerable ele- 

 vation. On Mt. Mola de Falset, Prov. Tarragona, at about 

 900 m., partly large specimens up to 10 mm. in length. Also 

 in the Sierra de Cardo near Tortosa at the mouth of the Ebro 

 I took it at an equal elevation, and south of the Ebro it was 

 found at 1000 m. on Monte Caro, opposite Tortosa. The 

 specimens from these southern localities run from 7 to 10 mm. 

 long, and vary considerably in the aperture, yet not so as to 

 require that special names be applied, as all transitions to 

 the typical form occur among them.
