NEW SPECIES AND RECORDS 

 OF PACIFIC AMPELISCIDAE 

 (CRUSTACEA: AMPHIPODA) 



By J. Laurens Barnard 



Associate Curator, Division of Crustacea 



Ampeliscidae from the east tropical and warm-temperate Pacific 

 Ocean and from warm-temperate Japan collected by the "Albatross," 

 "Velero III," and individual collectors are reported upon in this paper. 

 These records and descriptions complete an inventory of all Pacific 

 Ocean materials of this family collected by the two expeditionary 

 vessels, on which previous reports have been made by Holmes (1908), 

 Shoemaker (1925), and J. L. Barnard (1954a, 1960, 1964a). Ampe- 

 liscidae are among the most dominantly occurring families of sub- 

 littoral and bathyal depths. Of particular interest are three new 

 species of Byhlis from Japan which demonstrate a remarkable diversity 

 in that genus. 



This study was supported by the Richard Rathbun Fund of the 

 Smithsonian Institution and was part of a project organized by 

 Dr. Fenner A. Chace, Jr., to complete the analysis of important ex- 

 peditionary collections deposited in the U.S. National Museum. The 

 writer is grateful also to the Beaudette Foundation of California for 

 assistance in the completion of the work in 1960. 



Station data are presented in the list below. Depths are quoted in 

 fathoms as in the original data, but in the sections on distribution of
