HAAS: ABIDA AND CHONDRINA. 299 



so slender among my many hundred specimens. Tliis size 

 record influenced Pilsbry (XXV, p. 55) to think that P. pid- 

 chella was perhaps related to Granopupa granum. I figure 

 a Bofill cotype from the Valle d'Ager in Montsech (pi. 27, 

 fig. 6). 



"Whether Westerlund's var. manotiana belongs to pidchella 

 seems to me unproven, as the general locality "Spain" is 

 given. Perhaps it is a tooth combination (Par. 2, Col. 1, Pal. 

 2) pertaining to some other Spanish local race of C. avenacea. 

 Although by no means so variable in apertural dentition as 

 avenacea farinesi, yet pidchella is not altogether constant. 

 The following five tooth-combinations have come to my notice : 



Parietal 1 2 2 2 2 



Columella!- 1 1 1 2 2 



Palatal 2 1 2 1 2 



C. avenacea pidchella is confined to the Montsech Range, 

 where it replaces C. a. farinesi of the surrounding territory, 

 with great constancy in the above-mentioned differential char- 

 acters.

This local form has never been comprehensively treated, as 

 the Estudis of Bofill and Haas reached only to the limit of 

 its area. Only P. tarraconensis extends into the Llobregat 

 region (Est. V), and was noted thence as a form of C. avena- 

 cea farinesi. In a later work (Mol.luscos terrestres i d'aigua 

 dolga de la regio de Tortosa, in : Butll. Inst. Cat. Hist. Nat. 

 Barcelona, XIX, 1919, pp. 128-131), Bofill and Haas referred 

 to forms belonging here as Pupa (Modicella) avenacea.
