TABU-SIMA. 



Tabu-shima or Tobi-shima is a small island off Ugo Province, 

 lying near the west coast of Nippon, about eighty miles northeast 

 of Sado Island. In his Travels, p. 257, Adams writes of it as 

 " a small island about thirty miles from Niegata in Nippon " ; but 

 it is nearer eighty miles from Niigata. The name appears on some 

 maps as Tobi-shima or Tabo-shima. It is nearly opposite the peak 

 Tshio-kai-san, on the mainland of Nippon. The following species 

 are recorded :
