Explanation of Table I 



1. Under list of species: Series of numbers preceeding every species name is the IBM code 

 number for that species, and identifies that species on the IBM species-data cards. These 

 numbers can be referred to for any future programs which might be carried out utilizing 

 the data in this study. 



2. The systematic arrangement of species in this list follows a number of authorities including 

 Keen (1958), Mortensen's "Monograph of the Echinoidea", John Garth's various papers 

 on Decapod Crustacea of the eastern Pacific, Hyman's volumes on the invertebrates: 

 Protozoa through Echinoderms, and various other monographic series. Specialists may not 

 always agree completely as to the systematic arrangement, but an attempt was made to 

 consult with leading specialists in each group of invertebrates. 



3. Species names are not italicized, as the list of names were printed-out by an IBM machine 

 which has only one kind of type. 



4. The station numbers which are underlined are those stations at which living animals were 

 found for that species. 



5. Depth ranges are given in fathoms, since the original data had been plotted in fathoms, and 

 time did not permit a complete conversion to meters. 



6. Living depth ranges are given by a solid line, while distribution of dead shell or tests is 

 given by dotted lines. 



7. The code numbers (Roman numerals) under the Environment column correspond to the 

 numbers of the environments given throughout the text.
