AMPHIPOD GENUS PARATHEMISTO — BOWMAN

Figure 8. — Distribution of Parathemisto pacifica and P. japonica in the northwestern 

 Pacific. Positive stations indicated by solid symbols, negative stations by open sym- 

 bols. Circles, stations reported by Irie (1948). Squares, Albatross stations. Stars, 

 stations reported by Nakai (1955). Triangles, Carnegie Stations. The two southern- 

 most stations reported by Irie probably had P. gracilipes. Only P. japonica was 

 present at the Albatross stations in the Japan and Okhotsk Seas; both P. japonica 

 and P. pacifica at the two Albatross stations east of Japan; only P. pacifica at the 

 Carnegie stations. 



3. North Pacific Ocean: In figure 9 I have attempted to show the 

 probable limits of distribution of P. 'pacifica across the entire North 

 Pacific. The approximate southern boundary east of about 160° W. 

 is based not only on CCOFI material, but also on samples from cruise 

 VII of the Carnegie and the Northern Holiday Expedition of the Scripps 

 Institution of Oceanography. In the region between 170° E. and 

 160° W., no collections have been made available to me, but exten- 

 sions of the boundaries in the CCOFI area and in the northwestern
