since 1910 (for the year 1909). On 30 June.1940, the Bureau of 
Fisheries was consolidated with the Bureau of Biological Survey to 
form the Fish and Wildlife Service. In certain years two reports 
were published, e.g., in 1917, the reports for years 1915 and 1916. 
In the current study, the year covered by an annual report, rather 
than the year of publication, is cited. ]
