It will be seen that of the 29 species heretofore described and not 

 confined to the Hawaiian region, 10 occur iii China or Japan, 9 in the 

 East Indies, 7 in the North Atlantic and West Indies, and 5 in the 

 South Atlantic. Sixteen species are found in the western part of 

 the Pacific, showing that about 55 per cent of the species not peculiar 

 to the Hawaiian Islands are Asiatic in their relations. The T species 

 indentical with Atlantic forms offer an interesting problem which 

 may find its solution in the equatorial current which is supposed to 

 have formerly swept through the Central American region and 

 onward across the Pacific. 



It is highly interesting to find that the Pacific coast of America 

 is represented by but a single species, Afithoptiliwi inurrayi.) secured 

 by the Bureau of Fisheries steamer Albatross from Erben Bank, 

 off the California coast, and also in the Hawaiian region. This 

 species, however, was previously reported by Kolliker « as secured 

 by the Challenger off the coast of Halifax, in 1,250 fathoms, and by 

 Verrill as taken by the Albatross in 1883, and the Fish Hawk in 

 640-1362 fathoms. It occurred at a* depth of 545 fathoms on Erben 

 Bank. It is essentially a deep-water form and therefore apt to be 

 distributed widely. 



Mr. W. K. Fisher, in his excellent paper on the Starfishes of the 

 Hawaiian Islands, remarks on the lack of relation between the faunas 

 of our western coasts and that of Hawaii. In the preparation 

 of a report which the writer hopes to publish in the near future the 

 alcyonarian fauna of the Calif ornian coast has been studied with 

 some care, with the result that not more than one or two species are 

 found to be common to the two regions. 



Of the 68 species now known from the Haw^aiian region, 39 are, 

 so far as known, confined to that region, and the remainder show 

 the relationship of the fauna to be strongly Asiatic, but with 12 

 species identical with Atlantic forms, and almost no connection with 

 the fauna of the eastern coast of the Pacific.
