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 Neiv-Zealand 

 Seas. By Dr. James Hector, F.E.S. With Remarks hy 

 Dr. J. E. Geay, F.E.S. &c. 



1. Neohalcena marginata^ 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 novw-zealandice,GYa.j (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, which has 

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

 baleen. 



2. Euhalo'na australis^ Gray. (The Black Whale.) 

 Balcena antipodarum, Gray. 



Whalers do not distinguish two species ; and if the tympanic 

 bone of the second species cited belongs to Neohalania mar- 

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

 Zealand is different from that of the Cape. 



3. Megaptera novae-zealandioe^ 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 aiistralis, Gray. 

 (The Southern Finner or Hazor-back.) 

 Physalus antarcticus, Gray. 



The only reason given for distinguishing the above is the 

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

 to be very variable in colour, even from the same individual. 



5. Catodon macrocephalus, Lac^p. (The Sperm-Whale.) 



Several varieties of teeth are in the museum, and must 

 belong to different species. 



6. Delphinus 7wvai-zealandice^ Qiioy & Gaim. 

 A skull of this species in the museum has the intermaxillary
