Shell broadly elongate-conic, horn-colorecl, nuclear whorls 2, well 

 rounded, smooth except for microscopic granules. The early post- 

 nuclear whorls are marked by incremental lines which slowly concen- 

 trate into ribs. The later postnuclear whorls well rounded, marked 

 by strong, slightly retractively curved axial ribs which are not 

 strongly elevated. In the specimen described and figured, of these 

 ribs 15 occur on the last whorl behind the varix, 17 on the penultimate, 

 18 on the third from the last, 15 on the fourth from the last whorl, 

 which is the last ribbed whorl. The intercostal spaces and the ribs 

 are marked by slender incremental lines. Suture strongly constricted. 

 Periphery of last whorl well rounded. Base well rounded, narrowly 

 umbilicated, marked by the continuation of the axial ribs and incre- 

 mental lines which extend into the umbilicus. There is an exceed- 

 ingly heavy varix a little distance behind the peristome on the outer 

 lip. The aperture is broadly ovate, somewhat expanded and reflected, 

 dark edged and adnate to the preceding turn at the parietal wall. The 

 operculum is typically oncomelanid. The radula has the formula 



i-i-i 



-^:2-i-3:7:5. 



The specimen described and figured, U.S.N.M. no. 426224, has 7.3 

 whorls remaining and measures : Height 8.5 mm ; diameter 4.0 

 mm. This lot contains 44 specimens collected by Dr. Mary N. 

 Andrews at Soochow, Kiangsu Province, China. Ten of these, in- 

 cluding the specimen described and figured, yield the following 

 measurements :
