It is the purpose of this paper to present a list of the species of fishes known to occur along our Pacific coast, between the Mexican boundary and the boundary of British Columbia, together with notes on the dis-tribution, habits, size, value, etc., of each species, in advance of the pub-lication of a general descriptive work. The paper is to be considered mainly in the light of a contribution to our knowledge of the geograi)hi-cal distribution of fishes. The "common names" here given are, in all cases, those heard by the writers among the fishermen on different parts of the coast. Family BRANCHIOSTOMATID^. 1. Branchiostoma lanceolatum (Pallas) Gray.
