line. Also it differs from M. dulcis Pils. in having more conspicuous 

 spiral stria- and darker color, etc. 



I have collected only two specimens of this species. 



Macrochlamys fusanus n. sp. (PI. xxi, figs. 4-7) 



Shell depressed, dark-reddish colored, thin, translusent, glossy, 

 with very minute perforation. Surface marked with very slight 

 growth line, and under a strong magnification showing very scarcely 

 perceptible spiral stria;. Whorls $j4, slowly increasing, the last 

 comparatively narrow, rounded at the periphery, but showing the 

 almost obsolate trace of a peripheral angle. Aperture oblique, lunate, 

 the lip thin, simple, the columellar margin vertical. 



Alt. 3, greater diam. 5.5, lesser diam. 4.8 mm. 



Fusan, Korea. 



This small Korean species somewhat resembles the above-men- 

 tioned M. kuroshimana Hirase in general shape, but much smaller 

 with narrower perforation, higher spire, more convex whorls, less 

 striking sculptures and narrower aperture. I\I. cerasina is a larger 

 species with wider perforation, more convex spire and sharp peri- 

 pheral angle. 



I have only four specimens of this species.
