A JOURNEY TO THE NORTHERN PARTS OF 



ISE PROVINCE FOR COLLECTING 



LAND SHELLS 



By TOKUBEI KURODA, Assistant 



Quite a number of both land and fresh-water shells have been 

 lately sent to Mr. Hirase, to investigate and name, by a student of the 

 Mie-ken Normal School, Mr. Tajima Kanamaru, an earnest collector, 

 who has been doing- his best in collecting specimens for Mr. Hirase's 

 collection. 



During last summer vacation he made a journey to the neigh- 

 bourhood of Yoro Waterfall, exploring all the way here and there, 

 and the above mentioned shells were the results of the expedition. 



We have found a peculiar and rare species among them. Though 

 the specimen is young, it has certainly peculiar characteristics ; it is 

 quite depressed as a PUctotropis, and the umbilicus is much wider 

 than that of any other Ganesella. It is a variety of Ganesella 

 japonica. There is no doubt that it is a form of Ganesella japonica 

 carinata P. & G. from the neighbourhoods of Mt. Ibuki and Mt. Yoro, 

 differing from it "only in being depressed more severely. It is past 

 dispute that the more pressure increases the wider and larger the 

 umbilicus becomes. 



Upon receipt of this we wrote to Mr. Kanamaru asking its 

 locality, and we immediatly received his kind reply with a map of 

 the region. Though it was late, I determined to spare a week or 

 more for the purpose of exploring those regions. 



I lett Kyoto on the 23rd of October, and set out on the expedi- 

 tion. The following is an extract from my diary, which I now wish 

 to offer to the public, with acknowledgements for Mr. Kanamaru's 

 kindness and good offices which I had the honour of receiving from 

 him, while in the northern parts of Ise, despite that he was very busy 

 in his studies.
