lineating the general distribution patterns of the 

 species of fish considered in this paper, the sur- 

 vey data would appear to be adequate. 



For most species and in most areas there were 

 marked differences in the catch at adjacent sta- 

 tions. In preparing the species distribution 

 charts, the average number of fish per tow for 

 all stations lying within 30" latitude and longi- 



tude quadrangle areas was determined. The 

 contour lines were drawn on a basis of these 

 average values entered at the center of each 30" 

 quadrangle. Considerable smoothing and inter- 

 polation were still necessary, especially in cases 

 where the bathymetry required adjustments in 

 order to avoid contouring a species outside its 

 normal depth range as indicated by individual
