"Very brown; less solid and less lengthened than the pre- 

 ceding [elongatissima] , smaller and more striate than var. a 

 [Italian megacheilos] , with the same variations as to the in- 

 ferior angle of the aperture, but having the margin of the 

 peristome thinner, sharper, and reflected less flatly; 7-8 

 whorls. Length 8-9, diam. 3 mm. Pyrenees-Orientales. It 

 was this which M. Michaud had intended to publish under the 

 name P. farinesi, and M. Farines under that of P. pyrenaica. 

 It offers a subvariety of a very light corneous color, transpar- 

 ent, fragile, very much striate, from Barcelona (Des Moulins). 



Pyrenees-Orientales: la Preste (Farines, Fagot); also re- 

 ported from Luchon (Haute-Garonne) by Moquin-Tandon.

The arrangement of teeth is practically the same as in bigor- 

 riensis, but it is a less cylindric, lighter colored shell, with the
