BATHTPELAGIC SQUID BATHYTEUTHIS

in the 0, 1, 2 group. Both populations have specimens in the 1 , 2 group : 

 only one Antarctic specimen is less than 31 mm MIj (19 mm) ; only one 

 Atlantic specimen is greater than 19 mm ML (39 mm). Except for 

 the slight overlap in the 1, 2 group these two populations of ahysshola 

 are distinct in the number-combinations of suckers on the buccal 

 lappets. 



4. Bathyteuthis hacidifera — Eastern Pacific 



B. hacidifera is represented by nine specimens that exhibit six com- 

 binations of numbers of suckers on the buccal lappets (fig. 15). (This 

 does not include the combinations of numbers of lappets with a par- 

 ticular number of suckers.) There is a tendency toward increased 

 numbers of suckers in larger specimens; only the three larger speci- 

 mens (24 and 37 mm ML) have combinations that include 4 or 5 

 suckers (4, 5 and 2, 3, 4). Only one of the small specimens has 3 

 suckers, while the remaining individuals have combinations 0, 1 ; 0, 

 12-12 



The smaller specimens (less than 20 mm ML) overlap somewhat 

 with ahyHsicola from the Antarctic except that hacidifera has no 

 representatives with suckers and ahyss'tcola has none under 20 mm
