Clausilia paohyspira n- sp. PI- XXVII, flgs. 5, 6, 7. 



Shell club-shaped, the spire very thick, the apex large, obtuse ; 

 thin; yellowish corneous-white; closely and finely striate, the 

 striation not perceptibly coarser on the last whorl. Whorls 8 to 

 8J, moderately convex, the last strongly tapering. Aperture ear- 

 shaped, oblique, rather narrow, extending above in a large, 

 retracted sinulus. Peristome free and continuous, convex, very 

 thick, white, notched at the position of the superior lamella, on 

 the right side of which there is sometimes a low tooth. Superior 

 lamelk marginal, vertical, continuous with the spiral lamella, 

 which ascends to a position above the superior lamella. Inferior 

 lamella deeply receding, forming a strong fold within the throat, 

 vertically ascending, thick below, giving off a branch in the inter- 

 lamellar area, which curves again towards and crosses the inferior 

 lamella above. Subcolumellar lamella emerging, bounded by 

 grooves Principal plica arising near the peristome and penet rating 

 past the middle of the right side. Upper palatal plica sliort, 

 joined iu the middle by a narrow, nearly straight, rather weak 

 lunella, which becomes very weak below, but terminates in a snmll 

 nodule.
