The collections are brong'ht to the laboratory where the 

 several g"ronps are se])arated and accessioned. The data of the 

 log- is typewritten in dnplicate. The accession cards facilitate 

 reference to the data of the log and the material on the shelves 

 of the laboratory. These cards are arranged in numerical 

 order. Another series of cards is made on which the name and 

 mnsenm number of the species is placed when identification is 

 completed. The genera are arranged alphabetically. A museum 

 record is arranged in numerical order. 



In the work done prior to this date it has not been feasible to 

 secure complete hydrographic data concerning each station at 

 which hauls were made. Some observations were made as to 

 depth, condition of bottom, temperature, currents, etc., and in 

 each case a record was made of this data. With the facilities at 

 hand we have not felt that we could profitably attempt systematic 

 Iwdrographic w-ork of a sufficient degree of accuracy to make it 

 worth the effort expended. A'Ve hope to provide the necessary 

 equipment and workers to begin accurate hydrographic investi- 

 g'ation at each station. 



it Avill be apparent that this more or less mechanical part of 

 the work of the biological survey has been time consuming. It is 

 equally evident that the value of any results to be attained will 

 depend very largely upon the painstaking accuracy of this initial 

 work. A large part of the time we have been able to give to the 

 marine station work has been devoted to equipping for the survey ; 

 operating the launch and caring for it; preserving the material 

 and making suitable records. It was deemed expedient to con- 

 tinue this phase of the work until we had in a general way covered 

 the regions we had planned to explore, extending from Pt. Dume 

 to Newport Bay ancl Santa Catalina Island. 



The identification of the species of plants and animals collect- 

 ed is yet incomplete. We have fairly complete lists of the Star- 

 fishes. Brittle Stars, Crustacea and Fishes collected. The re- 

 maining material is in the hands of specialists for identification. 



In the groups of animals identified some new species have 

 been found and a much larger number of species well known else- 

 w^here have not previously been reported from this locality. Thus 

 among the Aniphipod Crustacea identified four new species are 

 found and the fishes in our collections contain more than a score
