THE CONCHOLOr.ICAL MAGAZINE 55 



For preservation, all the books concerning natural history, which 

 belong to the Yamamotos, are now stored in Mr. Iwase's library, at 

 Nishiocho, Owari. 



In concluding this short sketch of " Boyo's " biography, it may 

 be note.d that he was one of the students of Banzan Ono, a prominent 

 scholar of Chinese classics and a noted naturalist. His sons, Yoshitsu 

 the eldest and Keigu the third, were accomplished scholars. Mata- 

 ichi, the present head of the family and a famous historian, is the 

 eldest son of Yoshitsu. 



I regard it a great privilege to tell the public that such a famous 

 family has lived in this city, and in addition to their bright and 

 glorious deeds, has preserved numerous precious shells.

Kuroshima, Satsuma. 



This fine species is quite different from anything yet described 

 from Japan. It somewhat resembles M. perfragilis Pils. but much 

 depressed and smaller with less convex whorls, narrower last whorl, 

 wider perforation, narrower aperture, and much more angular out-
