CEPHALOPODA. — BERRY. 



205 



III. — Region Investigated. 



The region covered by the explorations upon which the 

 present paper is based includes the waters between Gabo 

 Island, Victoria, on the east, and Cape Naturaliste, Western 

 Australia, on the west. The bulk of the material, however, 

 was taken in the Great Australian Bight south of Eucla, and 

 in the immediate neighbourhood of Bass Strait. 



IV. — Geographical Distribution. 



The distribution of the various species, as well as a hint of 

 their zoogeographic relationships further afield, is brought out 

 as well as it can be at the present time in the accompanying 

 table (Table II.). For the sake of completeness I include 

 also such additional records for the species previously known 

 as I have been able to glean from the literature. Explana- 

 tions of the unceitainty indicated in some instances in the 

 table will be given in proper order in the main body of the 

 report. 



TABLE II. 



. . Records based upon material obtained by the " Endeavour." 

 . . Previous records. 



V. — Bathymetric Distribution. 



Most of the Cephalopods taken by the " Endeavour" are 

 from the upper oceanic strata, that is, from above the 100 or 

 150 fathom line. By adopting an increment of 150 fathoms 

 as the standard, and placing the first three such increments in 

 successive parallel columns with their appropriate species 

 listed below, all the " Endeavour " material arranges itself
