X. Japonic Province. 



The Japanese Islands, the coast of Mantchuria and part of 

 Corea represent the Japonic province. Our knowledge of its 

 marine fauna has of late years received several valuable acces- 

 sions. Of 429 species known in 1875, 145 or about one-third are 

 peculiar to the Japanese Archipelago ; 28 are common to the 

 coast of Mantchuria, which presents a more Arctic character ; 

 185 or about three-sevenths ai'e common to China and the 

 Philippines: 165 or about two-fifths, principally from the 

 'southern parts, belong to the Indo-Pacific fauna. 



A number of species are common to the West Coast of 

 America. The following have been cited. They may not all be 

 correctly identified, but on the other hand the list could be 

 readily made much longer : 



Siphonalia Kelletti. 

 Triton Oregonensis. 

 Nassa /estiva. 

 Oliva anazora. 

 Solarium quadriceps. 

 Haliotis gigantea. 

 Crepidula aculeata.
