Tago Bay, Suruga Gulf, in September, 1861, and there is no 

 doubt that this is the place referred to, lat. 34 48' K, long. 138

The following species were obtained ; only the first two have been 

 recognized with certainty by subsequent authors : 



Helix ( Camcena) peliomphala Pfr. 



Helix (Camcsna') myomphala Mart, [Ganesella wi.]. 



Helix (Fruticicola) textrina Bens, [certainly an error]. 



Helix (Fruticicola) sphinctostoma A. Ad. [ Ganesella] . 



Helix (Fruticicola) collinsoni A. Ad. 



Helix (Fruticicola) concinna A. Ad. 



Hyalina ( Conulus) acutangula A. Ad. 



CJausilia gouldi A. Ad. 



Clausilia spreta A. Ad.

 (p. 312). 



SlMODA. 



At the southern end of the peninsula formed by the Province 

 Izu, and notable as being the place first set apart for the use of 

 Americans, at the time of Commodore Perry's visit to Japan. 



Helix ( Camcena) qucesita Dh. 



Helix (Camcena) simodce Jay. 4 



Helix (Fruticicola') similaris Fer. 



TAKANO-SIMA AND OKINO-SIMA. 



Takano-shima and Okino-shima have been two of the most 

 problematic of Adams' localities, as the places to be found under 

 these names on Occidental maps are not Ihose visited by the 

 "Actaeon." The first clue I had to their true location was from 

 the Travels, p. 309, where Adams states that " on the east coast 

 of Nippon and not far from Tal iyama are two small islets named 

 Takano-Sima and Okino-Sima" 



On ordinary maps these islets are not even indicated. Hassen- 

 stein, on sheet IV of the folio atlas, maps them minutely, but 

 without names. Referring to a large-scale Japanese atlas in 47 

 sheets, I found the islets were duly indicated, and the names when 



* Adams gives H. Jierklotsi Martens as a synonym of simodce, which is 

 far from being the case.
