wide limits in all localities whence bigorriensis is known, and 

 that further, the shape of the aperture is by no means con- 

 stant, it is very hard to find characters for separation of the 

 races. Here, too, full-grown specimens but with the peristome 

 not completely developed have given occasion for the propo- 

 sition of new specific names, as will be mentioned under the 

 various local races.

I have nothing to add to Pilsbry 's description of this local 

 race. The cotypes before me from Bagneres-de-Bigorre 

 (Hautes-Pyrenees) agree fully with Des Moulins' description 

 and with Pilsbry 's illustrations. 



Pilsbry (I. c, p. 30) correctly treats P. moquiniana Kstr. as 

 a form of bigorriensis, not a distinct species. I was able to 

 compare specimens in Rossmassler's collection from the type- 

 locality, Mt. Beudat near Pau (not Beudar, as Pilsbry wrote, 

 p. 31), and to convince myself of the complete identity of 

 Kiister's form with bigorriensis. One of these examples is 

 drawn in pi. 26, fig. 1. 



The form described from the Cirque de Gavarnie (H.-Pyr.) 

 as Pupa badia var. gigantea has been elevated by Pilsb^ to a 

 species. According to the cotypes, of which I figure one on 

 pi. 26, fig. 2, I can see in var. gigantea nothing more than an
