Figure 45.— Distribution of Bathyteuthis ahyssiccla, B. bacidijera, and B. berryi in the 

 tropical eastern Pacific Ocean. 



Although presently there are no specimens to substantiate it, both 

 species of Batliyteuthk may be expected to range farther westward 

 in tlie Pacific Equatorial Water Mass borne by the deeper components 

 of the North and South Equatorial Currents, 



Bathyteuthis is presently unknown throughout the remainder of the 

 vast Pacific waters. Whether species will l:>e found to inhabit the 

 various Pacific water masses is difficult to predict; Bathyteuthis is rare 

 in salinities lower than 34.50%o. It may be excluded from the eastern 

 and western North Pacific Central Water Masses and the North Pacific 

 Intermediate Water Mass because these masses have salinities lower 

 than 34,50%o. Perhaps Bathyteuthis occurs at least in the cooler, more 

 saline waters of the southern eastern and western South Pacific Central 

 Water Masses. Because Bathytenthis is so widespread in the Antarctic, 

 Atlantic, and to a lesser extent the Indian and eastern Pacific Oceans, 

 in a variety of water masses, it would seem that a species should occur
