translated 5 proved them to be the islands of Adams. Under the 

 circumstances I have thought it not superfluous to give a sketch-map 



of so much of the southern end of Awa Province 6 as is necessary 

 to show the location of these type localities. At Taka-no-shima 

 (" Island of Taka ") only one terrestrial species was taken, Philo- 

 mycus bilineatus Bens. , probably P. confusus Ckll. 



Oki-no-shima, or as A. Adams, from some erroneous notion, 

 transposes it in some places, " Kino-O-Sima," lies west of Taka- 

 no-shima. The following species are recorded, only the first one 

 having been recognized by recent students of Japanese snails : 



Helix (Fruticicola) similaris Fer. 



Helix (Fruticicola) craspedocheila A. Ad. 



Helix (Fruticicola) proba A. Ad. 



Helix (Plectotropis) squarrosa Gld. [probably Plectotropis 

 vulgivaga]. 



Hyalina ? electrina Gld. [probably an error] . 



Clausilia stenospira A. Ad. 



Clausilia proba A. Ad. 



Clausilia pinguis A. Ad. 



In the Travels, p. 310, Adams mentions taking Helix simodce 

 and a little Bulimulus, and on the next page records Peronia 

 tongana from this place. 



5 Mr. Benjamin Smith Lyman, formerly of the Pennsylvanian and 

 Japanese Geological Surveys, was so good as to translate these as well 

 as many other Japanese place-names. 



u It may be needless to mention that there are two provinces called 

 Awa : that intended here, lying east of the entrance to Tokyo Bay, 

 and another in the eastern part of Shikoku Island.
