 STATES SCIENTIFIC EXPEDITION TO THE WEST COAST OF 

 AFRICA. 



BY 



James E. Benedict, 



Assistant Curator of the Department of Marine Invertebrates. 



The crustaceans emimeiated in tliis paper "were obtained by W. Har- 

 vey lirown and liis brotlier, Arthur II. Brown, during- the voyage of U. 

 S, S. Pensaeola on the recent eclipse expedition to St. Paul de Loanda 

 on the west coast of Africa. The ship sailed from New York on the 

 IGth of October, 1889^ stopping on the way at the Azores and the Cape 

 de Verde Islands, also at Free Town and Elniina on the Gold Coast, ar- 

 riving at its destination on theOth of December. After the eclipse the 

 ship sailed for Cape Town and then homeward, stopping at the Island 

 of St. Helena, Ascension Island, and Barbados. For the sake of com- 

 pleteness, the few. things obtained at this American locality are included 

 in the list. 



The collection, though not large, is as extensive as could be expected 

 where men were collecting in all departments in the limited time 

 allowed in the different ports. With the exception of a variety of Caili- 

 neeti'H Uimidus Ordway, none of the Brachyura are believed to be new. 

 However, the species obtained are valuable to the ^luseum collection, 

 in every case adding a species or a locality previously unrepresented.
