"Belongs in the kinship of P. antivertigo and stands es- 

 pecially near P. ovata Say, which differs, however, by the 

 somewhat slimmer shape, the last whorl somewhat compressed 

 at base, and by the somewhat stronger teeth" (Reinhardt). 



I have not seen this species. The second columellar tooth 

 described is what would now be considered a basal fold, sub- 

 columellar in position.

The shell is rimate, rather shortly oval, sayal brown, 

 opaque. The surface is very finely, sharply striate on the 

 penult and next earlier whorls, more coarsely and less sharply 

 so on the last whorl. The whorls are moderately convex, the 

 last not compressed below or impressed over the palatal region ; 

 it expands into a rounded crest close to the lip. The aperture 

 is ovate, with four well developed teeth : parietal lamella 

 rather long ; columellar lamella somewhat smaller ; two rather 

 small palatal folds, the lower one larger, as usual. In old 

 specimens, such as the figured type, there is also a very low, 

 almost inmersed basal fold (but in others this is wanting). 

 There is a rather thick palatal callus. The outer lip is 

 straightened and very slightly incurved in the middle, its edge 

 a trifle expanded. Length 1.8, diam. 1.15 mm.; 4% whorls.

It is distinguished from other Japanese species having a 

 crest and a palatal callus by the distinctly striate shell. It 

 was mentioned without description in Proc. A. N. S. Phila., 

 1905, p. 718.

 The shell is rimate, ovate, auburn. Surface glossy, nearly 



smooth, with only weak traces of striation. The whorls are 

 convex, the last not impressed over the palatal region, having 

 a strong, opaque buff crest behind the lip. The aperture is
