Cotypes no. 1,618 of my coll. and no. 84 of Mr. Otaki's 

 collection. 



This species resembles A', frateriia, but has more convex out- 

 line, whorls are narrower and more numerous. A', pagoduloides is 

 easily distinguished by its rounded periphery. 



This remarkable little snail is named in honor of Mr. Yiota 

 Otaki, who collected only two specimens. 



Kaliella multivolvis oshuensis n. subsp. Fig. 2.

South Nishigo, Minami-murayama, Uzen. 



Types in my coll. 



At first, I thought this was A. multivolvis, but by farther study 

 I have found that it is distinguishable from K. multivolvis (see pages 

 31 and 32 of vol. ii, no. 6).
