1. East Indian species, occurring in the Philippine Islands 

 and on the coast of Cochin China, reach northward as far as 

 Hong Kong, one of them possibly as far as Fuchow. 



2. Southern Japanese species range from Tokyo Bay westward 

 to the Korean Straits and thence southward along the Riu Kiu 

 Islands to Formosa and Hong Kong, where they occur together 

 with East Indian forms. 



3. Arctic species inhabit the cold water which bathes the 

 continental shores of the Sea of Japan, extending southward as 

 far at least as the Korean Straits, possibly even to Shanghai. 



4. Antarctic species inhabit the Pacific coast of Japan, and 

 reach their southern limit at Tokyo and Sagami Bays. 



From the coast of Asia between Cochin China and Korea we 

 know 36 species of unstalked crinoids of which 17 may lie 

 regarded as East Indian, 15 as southern Japanese, and 2 as 

 Arctic ; one is of very general distribution throughout the east- 

 ern tropics, and one is doubtfully East Indian, being related to 

 other species occurring in the Moluccas and at Tahiti. These 

 species, with their ascertained range in this region, are:
