GAMMARIDEAN AMPHIPODA 6 



Barnard (196Ga) concluded that the upper bathyal fauna of sub- 

 marine canyons and borderland basins of southern California has the 

 aspect of a submergent fauna of northern latitudes but the samples at 

 hand ameliorate the strength of that conclusion. Some species and 

 genera show a relationship to sublittoral cold-temperate and subarctic 

 faunas, as follows, Aceroldes spp., BathyTnedon spp., Para'phoxus 

 oculatus. But others, such as Flioxoceflialus herguelenl^ Arht'iopsis 

 tacita and species of Oedlceroides^ show a relationship to southern 

 hemisphere faunas. Leptophoxus falcatus and M onoculodes latiss'i- 

 inanus have affinities with the fauna of high north latitudes but popu- 

 lations of those species also occur in bathyal or abyssal waters of high 

 latitudes. The remaining species, of which a large proportion is new, 

 have their affinities with bathyal and abyssal faunas of seas in low 

 latitudes, thus suggesting the universal distribution of discrete 

 bathyal and upper abyssal faunas having little relationship to polar 

 sublittoral waters. 



I am indebted to Dr. Jolm S. Garth of the Allan Hancock Founda- 

 tion for making these collections available to me. Mrs. Dorothy M. 

 Halmos, Librarian of that foundation, assisted me with reference 

 problems. Some figures were drawn by Miss Jacqueline B. Hampton 

 and the Misses Vivienne and Rosalind Noon, and the remainder by the 

 author. All were inked by Miss Elaine R. Taylor. Assistance for 

 illustration was provided by the National Science Foundation 

 (G-10T50). The author is grateful for the aid of these persons and 

 agencies. 



Through discussions, lettei-s, and a manuscript revising portions of 

 the Lysianassidae, the author has been aided by Dr. D. E. Hurley, 

 New Zealand Oceanographic Institute, in composing the classificatory 

 remarks on that family. 



Dr. Meredith L. Jones of the Smithsonian Institution identified the 

 remains of polychaetes in the stomach of Parandaniexh mirahUis.
