The cirripedes have been neglected , by American zoologisis and, consequently, 

 aside from a few references to littoral species in Darwin's Monograph on Cirripedia, 

 almost noihing has been published upon the -west-American forms. The littoral 

 species, especially of Balanidse, stand in need of thorough sludy, while only a begin- 

 ning is now made in the description of the deeper-water forms, which will doubtless 

 prove inmierous. 



The following report is based upon collections made by the steamer Albatross 

 in Alaska and northwestern Washington in 1903 and off the coast of southern 

 California in 1904. 



It has not been thought necessary to give full references to the literature of 

 each species. Such bibliographic matter may be found in the following works:

cirripedes.
