MARINE BRYOZOA IN THE INDO-PACIFIC REGION 395 



The relationship between the Malayan and Papuan Provinces seems to 

 be less intimate than that of the Malayan and Chinese Provinces. 



Interrelationship of the provinces of Central and Eastern Pacific 

 Subregion: As Hawaiian and Polynesian faunas have not been thorough- 

 ly investigated, it is not easy at present to clear the true nature of their 

 relation to that of the Mexican Province. Excluding a large number 

 of endemic species, a fairly large part of the Hawaiian Bryozoa occurs 

 in Japan or in California. The Polynesian bryozoans present an in- 

 timate relation with Papuan forms, but a number of them have not 

 been found elsewhere. The Bryozoa of the Pacific coast of tropical 

 America have recently been thoroughly investigated by Osburn, and 

 Atlantic and Mediterranean elements observed in an eminent degree, 

 and the occurrence of a large number of specialized forms seems to prove 

 the propriety of the separation of this province. 



The details of the distribution of genera and species are to be re- 

 ported in our forthcoming paper.
