Bathymetrical and geographical distribution of Californian Alcyonaria. 



a Shallow water. 



[The asterisk (*) indicates a new species.] 



The most important fact brought out by the foregoing list is the 

 entire absence of forms known from the American coast north of 

 California. Aside from this purely negative showing, the most strik- 

 ing feature of the list is the remarkable diversity of the derivation of 

 this fauna, its relationships being almost exactly equal in respect to 

 the faunas of the Pacific coast south of California, the Western 

 Pacific, the eastern coast of the United States, and the West Indies. 



Another interesting feature is that the relationship with the Atlantic 

 and Pacific faunas is almost exactly equal. 



The collection is hardly extensive enough to warrant any generali- 

 zations, ;m<l even if this were not so, this singular equivalence of 

 relationship would signify little beyond the wide distribution of the 

 Alcyonaria in comparatively deep water.
