NO. 2 HARTMAN, BARNARD: BENTHIC FAUNA OF DEEP BASINS 



SYSTEMATIC ACCOUNT OF SOME MARINE INVERTE- 

 BRATE ANIMALS FROM THE DEEP BASINS OFF 



SOUTHERN CALIFORNIA 



By Olga Hartman 



INTRODUCTION 



All specimens, including holotypes, are deposited in the Allan Hancock 

 Foundation. Ecological data and records of associated organisms are 

 given in a subsequent part of this volume. Reference to bibliographic 

 citations may be found at the end of this account, and in Hartman, 1959. 



The collections were largely taken with a grabbing device called the 

 Campbell grab (Hartman, 1955a). This is not effective in rocky habi- 

 tats; animals characteristic of such bottoms are better recovered with a 

 dredge or trawl, such as were employed during the operations of the 

 USS ALBATROSS (reported by Moore, 1910 to 1923). Consequently 

 some of the deep water species named from basin depths of southern 

 California have not been taken during current operations. 



ACKNOWLEDGEMENTS 



I am indebted to the Administration of the Allan Hancock Founda- 

 tion for permission to study these interesting collections, for the use of 

 physical facilities, and for support. The operations of the VELERO IV 

 were partly financed by a grant from the National Science Foundation. 

 Most of the field collecting and sorting of animals to groups was done 

 under the direction of Dr. J. Laurens Barnard. Professor K. O. Emery 

 and his students recovered some "of the samples from the basins. Mr. 

 Anker Petersen prepared all the plates of illustrations. I wish to express 

 my gratitude to Captain Allan Hancock, who has continued to support 

 the marine researches of the Allan Hancock Foundation.
