Senzan, Awaji. Like Kobe shells, but sometimes smaller. Alt. 

 20, diam. 5 mm., whorls 8; alt. 17, diam. 4.5 mm., whorls 7J. 



Okinoshima, Tosa. Specimens like those from Kobe, but the 

 lip is sometimes appressed, not free above, and the superior lamella 

 scarcely marginal. Plication of the subcolumellar region variable. 



Ushirogawa, Tosa. Slightly smaller than Kobe shells and, like 

 the preceding lot, more opaque, the lunella not visible from the 

 outside. 



One specimen, sent at a different time from this locality (PL 

 XXXVI, fig. 22), retains the apex perfect, is reddish-brown, 

 slightly translucent, and has a much shorter principal plica, ex- 

 tending but a short distance beyond the lunella. There are 13 

 whorls, the earlier ones translucent-white. Length 25.5, diam. 

 5.9 mm. 



Fukuregi, Higo, Kiushiu. Rather small, with few or many 

 subcolumellar plications. Alt. 19, diam. 5 mm., whorls 9. 



Yatsushiro, Higo. Larger than the preceding; peristoine often 

 somewhat more solute than in Kobe shells, and the mouth a little 

 narrower. Alt. 2.4, diam. 5 mm., whorJs 10 J; alt. 21, diam. 

 5 mm., whorls 8J. 

 Clausilia plicilabris var. ptyoholaema Boettger. 



" Shell larger, more distinctly striate, the last whorl more 

 strongly rib -striate. Aperture longer, the peristome less calloused 

 and reflexed. Length (decollate) 20J-27J, diam. 5|-6f mm." 



" Seluchi, between Hiuga and Bugo " (Rein). 



Clausilia Oscariana Pilsbry. PI. XXXVI, figs. 30, 31. 



Pilsbry , in these Proceedings for 1901, Vol. LIII, p. 499 (October 2, 

 1901). 



Shell rimate, fusiform, rather acutely attenuated above, the 

 early whorls retained in adults; dingy brown; finely striate. 

 Whorls 10J to 11^, slightly convex, the last perceptibly constricted 

 behind the lip. Aperture ovate-piriform, the sinulus a little 

 retracted; peristome very shortly free above, not emarginate at 

 the position of the superior lamella, reflexed and thickened, crossed 

 by several folds {sometimes subobsolete') in the vicinity of the sub- 

 columellar lamella. Superior lamella marginal, rather low, 

 slightly oblique, widely separated from the spiral lamella, the latter 

 reaching a ventral position within. Inferior lamella very deeply 

 receding, scarcely visible from the mouth, extending inward nearly
