104 Dr. J. Hector on the Whales and 



a list of the species of whales according to the countries in which 

 they have been observed. 



XIII. — Notes on the Whales and Dolphins of the New-Zealand 

 Seas. Bj Dr. James Hector, F.R.S. With Remarks by 

 Dr. J. E. Gray, F.R.S. &c. 



1. Neohaloina viarginata^ Gray. 



The tympanic bone of the type of this species in the Colonial 

 Museum agrees exactly with the ear-bone on which is founded 

 Caperea novce-zealandice^GfT^ij (Cat. Seals & Whales, p.- 101). 



Practical whalers, after examining the baleen of this whale, 

 affirm that it is the Fin-fish or Sulphur-bottom, and that it 

 grows to an immense size. It is not the Finner, Avhich has 

 the dorsal fin fiuther back. They judge by the colour of the 

 baleen. 



2. Euhalcena anstralis^ Gray. (The Black Whale.) 



Bala:na antipodarum, Gray. 



Whalers do not distinguish two species ; and if the tympanic 

 bone of the second species cited belongs to Neohalama mar- 

 ginata^ there is no evidence that the Black Whale of New 

 Zealand is difierent from that of the Cape. 



3. Megaptera novce-zealandice, Gray. 

 This species is also founded on a tympanic bone. A whale, 

 34 feet long, with a, falcate dorsal fin, stranded in Wellington 

 Harbour, has a similar ear-bone, and may be this species. 

 The bones were unfortunately lost. 



4. Physalus australis^ Gray. 

 (The Southern Finner or Razor-back.) 

 Physalus antarctieus, Gray. 



The only reason given for distinguishing the above is the 

 colour of the baleen. Whalers state the baleen of the Finner 



5. Catodon macrocephalus, Lacep. (The Sperm-Whale.) 

 Several varieties of teeth are in the museum, 

 belong to different species. 



G. Delphinus novce-zealandice^ Qi^oy & Gaim. 

 A skull of this species in the museum has the intermaxillary
