Besides these differences, the carpal arrangement of suckers and 

 pads is slightly different. The Philippine specimens lack any pig- 

 mentation but the Atlantic subspecies is a rich wine red. 



Remarks. — The subspecific name pacifica is given to distinguish 

 this group fromi its Atlantic counterpart. Inasmuch as the species of 

 Calliteuthis are all widespread bathj^ielagic forms, C. celetaria pacifica 

 will undoubtedly be found tliroughout the Pacific region. It resem- 

 bles no other Indo-Pacific form.

Description. — The mantle is roundly conical and fleshy, the wall 

 thick. The width is slightly more than half the length and greatest 

 just posterior to the anterior border. DorsaUy the anterior margin is 

 sharply produced, but ventrally it is truncate. Posteriorly the 

 mantle ends in a blunt point. The midline of the mantle dorsally has 

 a row of about 17 small tubercles occupying a raised ridge on the 

 anterior two-thu'ds of the mantle. 



The head is large, about half as long as the mantle and nearly or 

 quite as mde. The ej^es are very disproportionate; the left ej^e is 

 about tAvice as large as the right eye and lies considerably posterior to 

 it. 



The funnel is smaU with a narrow opening and is equipped with two 

 strong supports or bridles. There is no apparent funnel groove in the
