BEANIA 4 i S 



(75 • J • 5 • 75) both belong to Hincks's species. True B. magellanica is, however, found 

 in New Zealand, for Waters (1906, pp. 14, 15) and Livingstone (1929, pp. 59, 60) both 

 recognized the two species. The British Museum possesses a dozen specimens of 

 B. bilaminata, all from New Zealand, one of which was figured by Hastings (1939, 

 text-fig. 273 B, p. 328).

Station distribution. Not represented in the Discovery collections. 



Geographical distribution. Kerguelen (34 . 1 1 . 1 2 . 9) ; Heard Island (Busk). 



Holotype. Challenger St. 149 D, Kerguelen, 34. 11. 12.9. This specimen was found among 

 unnamed material in Busk's collection. 



Description. Zooecia erect, straight-sided, rectangular distally, with a peg-like spine 

 at each corner (Fig. 34 B). One small marginal spine (rarely two) frequently present on 

 each side of distal half of opesia (absent in the figured zooecium). 



1 The varietal name is not available for the new species as it is preoccupied by B. distans Hincks (1881).
