List of Species Taken at "Albatross" Dredging Stations During the Years 



1912 and 1913 



Only such data are reproduced here as have been used in the discussion of the 

 distribution of the species listed. All other dredging data are to be found in 

 the Report on the Physical Conditions in San Francisco Bay (Sumner, 1914). 



Unless obtained at more than three stations the species and number of speci- 

 mens taken at the various stations are entered in the column of ' ' Addenda. ' ' 

 Cancer antennarius is the only exception to this rule. 



Fifty or more specimens are represented by the letter "m" (many). The 

 actual count of lesser numbers is given in full. 



The positions of these stations are plotted on plates 2 and 3, and in order 

 that they might be readily located they are referred to the "upper," "middle" 

 or ' ' lower ' ' regions of the bay or to the region ' ' outside. ' ' 



The "upper" bay is taken as the section lying north of a line connecting 

 Point San Pedro and Point San Pablo, including the region usually designated 

 as San Pablo Bay. The "middle" bay extends from this line to one drawn from 

 the San Francisco Ferry Building through the Goat Island Light, and separating 

 it from the "lower" bay, the section below this latter line. The "middle" bay 

 is separated from the region "outside" by a line passing from the Bonita Point 

 Light through Mile Kock to the San Francisco shore. 



As a rule hydrographic observations were not made in the course of dredging 

 operations, and in order that such data obtained at the regular hydrographic 

 stations might be used in connection with the dredging stations a table, correlating 

 the two has been drawn up as Appendix III (p. 354) of this report.
