272 HAAS: ABIDA AND CHONDRINA. 



curred, and that the described varieties of secale from the 

 Pyrenees were referable to that race. Our entire knowledge 

 of boileausiana rested hitherto on Kiister's description and 

 illustration, and both of these give the impression that we 

 really have to do with a species or subspecies close to secale, 

 but yet quite separable from that. However, I now find in 

 the Rossmassler collection a number of specimens of an Abida, 

 received from Charpentier, and which he had himself marked 

 as his boileausiana. They vary somewhat in size, and the 

 aperture is not equally developed, but they agree, except for 

 small discrepancies in the degree of strength of the several 

 teeth, and in that the supracolumellar tooth is wanting. The 

 aperture thus appears 8-toothed, as Kiister said at first, al- 

 though in the further course of his diagnosis he enumerates 9 

 teeth. In my opinion, which is sought to be proved by an 

 illustration of one of these Charpentier examples (pi. 23, figs. 

 5, 6), P. boileausiana can no longer be retained as a separate 

 species or subspecies, but must be gathered into the synonymy 

 of A. secale as one of the forms of its great range of variation. 



Bofill and I (Est. V, p. 368, pi. 3, figs. 12, 13) have been 

 able to bring Pupa lilietensis Bofill back to A. secale as repre- 

 senting a thin-shelled and therefore only weakly-toothed form. 

 Pilsbry did not know this form, and mentioned it (Vol. XXIV, 

 p. 293) among Bofill names without indication of its affinities. 



The other described forms of secale from the Pyrenees fall 

 within the range of its variation, and their names in my 

 opinion can pass into its synonymy. Var. cylindroides M.-T. 

 is somewhat more cylindric; var. elongata Saulcy somewhat 

 longer than the typical form, 9 mm. instead of 8 mm., and I 

 could specify still longer ones from several localities further 

 south. Var. phymata West, is only a thick-shelled form, there- 

 fore with a strong peristome, which from its other qualities 

 seems to be a true boileausiana. Pupa fagorum Fag., of which 

 I can figure a cotype from Aulus, Dep. Ariege (pi. 23, figs. 7, 

 8, 9), is on the contrary a thin-shelled form without thickened 

 peristome, and completely identical with the var. abrupta 

 West, from the same locality. Of Pupa goudoniana Fag. and 

 costata Fag. I do not venture to speak positively, whether
