NOTES AND EXHIIUTS. 945 



the description furnished it would seem to have been a Finback 

 or Rorqual ( Bahanoptera). There was a patch of barnacles on 

 the breast 4 ft. square, from which the specimens exhibited were 

 secured. There were also several other large patches on the 

 whale's belly, the individuals being of about the same size as 

 those collected. Through the disintegration of the outer walls, 

 the compartments in the barnacle-shells had in many places 

 become exposed, and where these were not fully occupied by the 

 epidermis of the whale, they were completely filled with numbers 

 of the Whale-louse {Cyamus ceti, Linn.). These crustaceans 

 were also crowded round the bases of the barnacles and were of 

 all sizes up to about 13 mm. in length. Growing from the 

 summit of the Coro7iula in many instances were numbers of a 

 stalked barnacle — a species of Conchoderma (probably C. auritay 

 Linn.). 



" Regarding the occurrence of Coronula diadema in these seas, 

 Darwin, writing in 1854 (Monog. Cirrip. Balanid^e, p. 419) 

 stated: — 'There is also a specimen in the British Museum sent by 

 Mr. Stephenson, mingled with shells of mollusca from New Zealand; 

 but a Coronrda procured from a whale in the early part of the out- 

 ward voyage might so easily be sent home with specimens subse- 

 quently collected in another county [? country] that I do not as 

 yet fully admit that this species is an inhabitant of the Southern 

 Pacific Ocean.' Under these circumstances, therefore, the new 

 record is of more than ordinary interest. 



^^ Coronula diadema, Linn., has been taken from whales in the 

 Arctic Seas, those of the United States and Great Britain, the 

 Gulf Stream, the Atlantic Ocean, and now from New Zealand. 



"The Whale-louse, Cyamus ceti, Linn., was recorded from these 

 seas for the first time in 1884 b}^ Chilton (Trans. N.Z. Inst, xvi.,
