steam-boat " the Oki Marti " bound for the Oki Is. I stayed in the 

 islands for 35 days, and made explorations. It was on the 22nd of 

 Sedtember that I came back to Sakai where I landed at once, and 

 explored much of the neighbourhood. Then I continued to explore 

 Mt. Makuragi, Kiyomizu, Mihonoseki, Mt. Daisen and Mikuriya 

 until the 5th of October ; thence I proceeded to Kizuki and Gakuenji 

 whence I went over to the southern districts. 



I laving made explorations at Yunotsu, Oyetakayama and also 

 in their neighbourhoods, I came to Hamada where I tried to collect 

 some more in the vicinity. Then I set out on the expedition to 

 Mt. Kakinoki, Mt. Taima and Tenjinjima, spending a few days at 

 each place. 



As it was growing quite chilly, I set out on my way home on 

 the steamer the Chiga Maru on the 17th of October. 



Of those trips, in short, that to the Oki Is. was the most fruitful, 

 and interesting, because I had been able to collect a good many rare 

 species. There were found very few in the San-in-do, both species 

 and specimens being very scarce and common. 



I was, however, lucky to learn how they were distributed there, 

 and so I am well convinced that I have had the honour of contribut- 

 ing a little to this branch of study. 



Of Helicidce, Eulota luhuana idzumonis spread all over Hold 

 Province, and extended as far as the interior south of Hamada. 

 Some large ones of the same were found in Oki Is. 



Eulota callizona dixoni spread through Izumo and Hold, and 

 inhabited even in some parts of Iwami where it seemed to mixwith 

 /:'. c. minor inhabiting in Nagato. Another variety was found in 

 Oki Is. also. 



E. callizona maritima seemed to have come over the range that 

 separates the San-in-do from the San-yo-dd, and settled at Yunotsu, 

 Iwami Province. But I could not find any of the same anywhere 

 in the north-eastern districts. 



Those three were the most common species that could be found 

 everywhere in the San-in-do. 



I should like to say something more about Ganesella, Plcclo- 

 tropis, Clausiliidce and Cycloplwridcc and etc. But as there is no 

 space left, I am obliged to given up my pen.
