At San Diego Bay headquarters were established at Roseville, 

 and the greater part of the collecting was done within a radius of 

 three or four miles of that point, though nearly all parts of the 

 bay were reached. Collections were made with the aid of fine- 

 meshed seins, fyke nets, and set-lines. A few trips were made 

 with fishermen hand-line fishing to the deep waters outside of the 

 bay, and frequent visits weve made to the tide pools on the ocean 

 side of Point Loma, principally to the pools near the outer light- 

 house. Owing to our distance from San Diego, it was not found 

 practicable to do much market collecting. 



To make the records of distribution of species more depend- 

 able, a reference is given to some authority for each record, 

 except when the authors are themselves responsible. In the latter 

 case the species has either been taken at the locality noted or is 

 in the collection of Stanford University. Species having a cos- 

 mopolitan distribution are not so treated. In preparing these 

 ranges of species, a series of notes made by Dr. Gilbert, which he 

 has kindly placed in our hands, has been of great assistance, and 

 has added materially to our knowledge of distribution of west- 

 coast fishes. 



We wish to thank Dr. C. H. Gilbert for making the trips to 

 San Diego in 1902 and 1903 possible ; Dr. W. E. Ritter and Dr. 

 Fred Baker for making the trip of 1905 possible under the aus- 

 pices of the Marine Biological Association of San Diego; and 

 Dr. Baker especially for his hospitality and much aid in making 

 collections.
