ABIDA. 289 



obtuse. Whorls 10, the first a little convex, the rest nearly 

 flat, suture not impressed, the last whorl larger, compressed, 

 ascending to the aperture, and somewhat crested around the 

 umbilicus. Aperture not oblique, irregularly oblong, seven- 

 toothed: two parietal folds, one being nearly in the angle, 

 strong, bified and reaching the margin, the other minute, 

 deeply placed. Two compressed columellar folds, very deep 

 in the throat. Three slender palatal folds, the lower remote 

 and short, sometimes wanting, the median somewhat remote, 

 the upper one almost marginal. Peristome a little thickened, 

 continuous, free, reflected throughout, white. Length 8, diam. 

 3 mm. (Fagot).

According to Fagot, this shell is more fusiform than P. 

 affinis, more compressed above, more thick-set, more cylindric, 

 and with the apex more obtuse; its aperture is continuous, 

 detached and reflected; the columellar folds are more im- 

 mersed, etc. It is larger than P. vergniesiana, more finely 

 striate, the aperture straight, not inclined, and a little de- 

 tached from the preceding whorl ; its palatal folds are thinner, 

 etc. It is more fusiform than P. pyrenearia, the last whorl 

 more compressed, strise lower, and the whorls less swollen, 

 not to mention its length, etc. 



M. Fagot holds that the identifications of this species by 

 Dupuy, Pfeiffer and Westerlund are incorrect; and as I am 

 not in a position to decide, and the original publication of 

 Boubee is not accessible to me, his definition is given above. 



The descriptions of several other related forms of unsettled 

 status follow.
