in the rest of the Pacific also. The diverse water masses in which Bathy- 

 teuthls has been found, however, all have salinities higher than 34.50%o 

 in the temperature range of Bathyteuthis (except in some of the 

 Antarctic Intermediate Water) ; the salinities of the Pacific water 

 masses (except Pacific Equatorial and Transitional) are all lower than 

 34.50%o at temperatures below 8° C. Possibly factors other than those 

 of the physicochemical environment combine to limit the distributions 

 of Bathyteuthis, 



Atlantic Ocean 



The distribution chart shows that B. ahysslcola has been captured 

 at widely scattered points throughout the Atlantic Ocean (fig. 50). 

 The species is common in the eastern South Atlantic wliere exploratory 

 fishing has been relatively light. The Dana made a mnnber of captures 

 during her northward passage; the PiUshury caught several speci- 

 mens during two cruises to the Gulf of Guinea; and the Chain has 

 made two captures in the region. On the other hand, exploratory 

 fishing has been very heavy in the western Atlantic, the Gulf of 

 Mexico, and the Caribbean Sea, but B. ahyssicola has been collected
