THE DISTRIBUTION OF CERATIAS HOLBOLLI 23 



macrofauna. The results may suggest that some bathypelagic Squids and fishes are more common and 

 achieve greater sizes than is at present supposed. 



When the new specimen was found, the floating factory was in position 6i° 20' S, 102° 50' E, and the 

 sperm whale must have been shot within, at most, 100 miles radius of this position because the whale- 

 catchers never steamed farther than this distance from the factory during the season. The area (200 miles 

 in diameter) is not only well within the limits of the Antarctic Convergence (Mackintosh, 1946, pi. i) 

 but also within the limits of the pack-ice (Mackintosh & Herdman, 1940, pi. lxxv), so that the 

 specimen may properly be said to be Antarctic in origin. The chart shows soundings within this area 

 varying from 4260 to 4400 m. which means that the sperm whale must have taken the fish at some level 

 in water which was at least 4260 m. deep. There is evidence that a Sperm whale may sound to 500 

 fathoms or 900 m. (Laurie, 1933) but it is possible, as will be seen later, that the fish may have been 

 captured at a quite shallow depth.

HORIZONTAL DISTRIBUTION 

 The geographical distribution of C. holbolli is shown in Table 3 and Fig. 6. Bertelsen considered 

 that C. holbolli was widespread in the tropical and subtropical parts of the ocean, but reserved his 

 C. tentaculatus for more southern latitudes. Regan & Trewavas (1932, p. 13) similarly considered that
