350 Fishes of the Pacific Coast of America. 



Point Conception. This division was the result of insufficient ex- 

 ploration, and the results mentioned above have made it evident 

 that no definite boundaries can be assigned for a Northern and a 

 Southern California fauna. 



It is quite evident, and readily admitted, that the fauna of Cali- 

 fornia is distinct from the Alaskan fauna, and the latter has been 

 added for convenience and comparison only. But four of the species 

 found at San Diego are also found in Alaska. The California fauna 

 is characterized by the abundance of species of Sabastodes, of Cott- 

 idae, and of Embiotocidse. The last are entirely absent from Alaska, 

 while only a few species of Sebastodes are found there. The boun- 

 dary between these two regions lies somewhere between Sitka and 

 Puget Sound. No Embiotocidaa are found at Sitka. 



The relative number of species at the principal localities is as 

 follows : — 



The whole of Alaska 



Puget Sound . 



San Francisco 



Monterey 



Santa Barbara 



San Pedro 



San Diego, including Cortes Banks 



There are known from the entire region 382 species, belonging 

 to 228 genera. Of these, 116 genera or more than half, are also 

 found in the Atlantic Ocean, and 32 species are found both in the 

 Atlantic and in the Pacific. 



The genera having species in both oceans, practically all belong 

 to one of three classes : 1st. Tropical genera ; 2d. Arctic genera, 

 whose species are distributed throughout the Arctic seas; 3d. Pela- 

 gic and other genera, having a wide distribution. 



Lists similar to the present were published by Jordan and Gilbert 

 in the Proceedings TJ. S. National Museum for 1880, for the shores 

 from San Diego to Puget Sound, and by Bean (1. c, 1881) for 

 Alaska. 



I have endeavored to give definite localities for the region from 

 Ensenada, Lower California to Puget Sound. Those recorded 

 from Alaskan waters have all been lumped into the general locality 

 " Alaska." No definite localities have as yet been published for 

 the species discovered by the Albatross.
