CRUISES OF THE "EAGLE" AND "ARA," 1921-1928,

By Lee Boone. 



Introduction, 



The Crustacean collection of the Vanderbilt Marine Museum was 

 obtained by Mr. WiUiam K. Vanderbilt on a series of cruises con- 

 ducted in his yachts, ''Eagle" and "Ara," during parts of the years 

 1921 to 1928, inclusive. The report on the Stomatopoda and Bra- 

 chyuran Crustacea collected on these expeditions comprises Volume 

 II of the bulletin series of the Vanderbilt Marine Museum. The 

 Anomura, Macrura, Schizopoda, Isopoda, Amphipoda, Mysidacea, 

 Cirripedia and Copepoda form the subject of the present volume. 



Four distinctly separate faunal regions are involved in these ex- 

 plorations: (a) The West Indian region, from which the greater per- 

 centage of species was obtained. Separate cruises during the years 

 1921, 1922, 1923, 1924 and 1925 were conducted by Mr. Vanderbilt in 

 this region. Some very valuable material was obtained in the West 

 Indies in 1926 and also in 1928, supplementing the Galapagan expedi- 

 tions of those years. 



(&) The Labrador-New England region is represented by material 

 collected in the waters of Newfoundland, Nova Scotia, eastern Canada, 

 the coast of Maine and of New York, including Long Island Sound, in 

 1921, 1922, 1924 and 1926. 



(c) The tropical American Pacific fauna is represented by explora- 

 tions in the Galapagos Islands, the west coast of Costa Rica and of 

 Panama, including the Perlas Islands, and Cocos Island, also several 

 deep-sea stations in this region, during the expeditions of 1926 and 

 1928. 



(d) The Mediterranean fauna, with especial reference to the north 

 coasts of Morocco, deep-sea dredgings off the coast of southern France, 

 off Sardinia and off Monaco and explorations of the littoral fauna of 

 the Adriatic Sea.
