NOTE. 



Professor Turner, F.R.S., lias kindly undcrtakeu the description of the Cetacea, the 

 Seals, and the hv;man remains procured by the Expedition. The present paper deals 

 with the Whales only. Unfortunately only a few Cetacean bones were found ; Professor 

 Turner has, however, been able to make some most interesting observations, particularly 

 on the structure and development of the teeth in MesopJodon. 



The trawl br(3ught up from the greatest depths of the Pacific a few bones of the 

 skeleton, and especially a considerable number of ear-l)ones of whales and porpoises. 

 The determination of the species to which these remains lielonged was a matter of great 

 interest, but one of extreme difficulty, on account of their fragmentary nature. They 

 were always mixed, as Professor Turner mentions, with the teeth of known Tertiary 

 sharks, and with nodules of oxides of iron and manganese ; and their occurrence under 

 the conditions under which they were discovered, is among the most curious and 

 interesting results of the Expedition. 



This paper was received on the 2d of Augu.st 1879.
