at the base, as in the species of the affinis subgroup; (3) by 

 having the lip-margins not united but separated; (4) and 

 especially by its dentition; all of the lamellae are prominent 

 and robust, the upper columellar emerges to the peristome ; 

 the columellar lamellae and the median parietal are exactly 

 opposed to the palatals, instead of alternating as in P. 

 pyrencearia (it is the same with cereana in comparison with 

 avenacea) ; this gives the aperture the appearance of being 

 obstructed by the nearly touching lamellae. The angular 

 lamella is often double. Finally, one or two supplementary 

 punctiform palatals may be seen between the upper palatal 

 and the suture; characters very well indicated by Kuester 's 

 figure (Fagot).

 footpath of San Julia de Loria at Andorra, on the Spanish 

 slope of the Pyrenees (Fagot).

According to Fagot, this shell was first found by Professor 

 Al. Braun in the environs of Prades at Villafranche sur la Tet 

 (Pyrenees-Orientales), who communicated specimens to Pro- 

 fessor Moquin-Tandon. Some were sent, with the Ms. name 

 Pupa saxicola M.-T., to Charpentier, and were figured by 

 Kuester. 



Fagot has given an incorrect reference to Kuester, but his 

 meaning is evident. He considers P. pyren&aria var. saxicola 

 of Moquin-Tandon 's Moll, de France different. 



20. ABIDA BOFILLI Fagot. Having the external appearance 

 of a small Pupa affinis, this new species is related by its teeth 

 to P. aulusensis. P. bofilli is easily separable from pyren&aria 

 and the related species by having the peristome not contin- 

 uous, the shell lengthened-fusiform, etc. Length 8, diam. 2 

 mm. (Fagot) . Related to petrophila, from which it differs by 

 the more delicate striations which give the shell greater bril- 

 liance; by the less large aperture, and the less robust aper- 

 tural lamellae, which are arranged nearly the same. On rocks
