species liave a range even southward of this fauna to the coast of 

 Oregon. It apparently corresponds to the Syrtensian Fauna of Pack- 

 ard,* on the Atlantic coast of America. 



The Oregonian Province. — This division includes Puget Sound, 

 in part at least, and the Coast of Oregon, extending to Cape Mendo- 

 cino, Cal. It api)ears to be the western representative of the Acadian 

 Fauna on the northeast coast of America. Tliis is not equivalent to 

 the Oregonian Province of Forbes, which extended from Columbia 

 River to San Diego, including, therefore, this and the following. 



The California^ Province. — This occupies the coast from Cape 

 Mendocino to Santa Barbara, and perhaps farther southward, and in- 

 cludes the Santa Barbara Islands, corresponding therefore with the 

 limits assigned ly Dana, while later this name was applied by 

 Forbes to the fauna occupying the coast of the peninsula of Lower 

 California. 



It appears to represent the Virginian Fauna of the Atlantic coast. 

 Many species are common to this and the Oregonian, while a large 

 per cent, so far as now known, are peculiar to each. Numerous rep- 

 resentatives of the genus Asterias give a peculiar character to both ; 

 and the genus Dendraster is not known elsewhere, except in the Sit- 

 chian Fauna. Loxechinus purpuratus and Toxopneustes Franciscana 

 are peculiar and characteristic species of the Californian Province. 



The Diego, and the Sonora Provinces, indicated by Prof Dana, are 

 almost unexplored for their Echinoderms. The former extends, ac- 

 cording to Dana, from latitude 28|^° to 34^°, and the latter occujjies 

 the coast southward along the peninsula of Lower California, nearly 

 to Margarita Bay, It is probable that some of the species described 

 as from " California" belong to this almost unexplored region. 



The Panamian Province. — This includes the Gulf of California, 

 and on the coast extends from Margarita Bay, Cal., to Cape Blanco, 

 Peru. It corresponds with Dana's Tropical Sub-kingdom and includes 

 three subdivisions : The Mexican District or Province, including the 

 Gulf of California, Cape St. Lucas, and the Mexican coast to Acapulco 

 or beyond ; the Panama District, including the coast of Central America 

 and the Bay of Panama ; the Ecuador District, occupying the coast 

 southward from Panama Bay to Cape Blanco, Peru. These correspond 

 nearly with those given by Dana, who considered them three distinct 

 Provinces. Concerning the northern limit of this fauna there has been 

 a pretty close agreement. Its southern limit, however, has not been so 

 well established. Forbes included the coast only to Guayaquil, while
