taxa include rattails, Synaphobranohus kaupi and 

 Ophiomusium lymani. 



(3) As was found in Lydonia Canyon the fauna of Oceanog- 

 rapher Canyon is composed of a variety of trophic 

 types throughout the depth range surveyed. Again 

 sessile filter-feeders such as corals and sponges 

 comprise a substantial proportion of the total 

 fauna. Deep in the canyon axis the deposit-feeding 

 ophiurid Ophiomusium lymani predominates. 



(4) Both hard and soft substrate corals are common in 

 Oceanographer Canyon. Two gorgonians, Paramuriaea 

 grandis and Aaanthogorgia armata^ are the most 

 abundant corals found in this canyon. Other common 

 corals include Anthothsla grandiflova^ Anthomastus 

 agassizii ^ Desmophyllum avistagalti , Distiahoptitum 

 graaile and Pennatuta aculeata. 



RECOMMENDED ADDITIONAL STUDIES 



A more thorough elucidation of the factors controlling 

 epifaunal distribution is recommended. This study should be 

 directed towards a better understanding of the interactive 

 roles that biological, physical and chemical processes play 

 in determining the distribution of the epifauna. Many of the 

 major faunal components identified in the present study are 

 patchily distributed, as is evidenced by such highly localized
