NO. 5 BARNARD: AMPHIPODA 107 



These 9 samples, of which only one lacks amphipods, have 72 speci- 

 mens. As in the 701-800 depth group, a Monterey sample is present with 

 Protomedeia articulate, untypical of canyons in southern California. 

 Otherwise, these samples are dominated by the blind subspecies of Ampel- 

 isca macrocephala and mixture is seen by the presence of Paraphoxus 

 daboius, with the deep water harpinias, ampeliscas and byblises, the deep 

 water species clearly dominating these depths. 



1001-1620 m 

 ampeliscids, fragments, 2 Oediceropsis (Paroediceroides) 



Harpiniopsis petulans, 1 trepadora, 1 



Harpiniopsis profundis, 1 Tryphosa index, 1 



Aletopa samsiluna, 1 



Only one of these samples lacks amphipods, the other 4 bearing 7 

 specimens. These samples are most interesting because in their respective 

 areas they are just above sill depths of San Clemente Basin or are in the 

 Coronado Canyon. They are the deepest canyon samples above sill 

 depths. Three of the species are new, so that the fauna reveals no rela- 

 tionship to either shallower depths of canyons or subsill faunas of basins.
