94 Transactions.— Zoology. 



The synonyma will, therefore, run thus : — 



Balcviia marginata, Gray, Zool. Erebus and Terror, t[>. 48, t. 1, f. 1 (baleen 

 only). 



Caperea antipodarum, Gray, P.Z.S., 18G4, p. 202, fig. j Cat. Seals and 

 Whales, p. 101, fig. 9 (ear-bone only) ; Cat. Su])pl. (part only). 



NeohaJcena marginata, Gray, Ann. and Mag. Nat. Hist., 1870, Y., p. 221 ; 

 YI., p. 155, figs. 1 and 2 ; Suppl. Cat., p. 40, f. 1 and 2 (drawing of 

 skull only). 



I applied the name of antipodarum to this species, believing it to be the 

 Black Whale of New Zealand, of which Dr. Dieffenbach had brought such an 

 accurate figure ; and I was confirmed in thinking it the same as the skeleton 

 from New Zealand, which was in the Paris Museum, by the observations of 

 M. Milne-Edwards, Professor Lilljeborg, and Yan Beneden, who, though the 

 skeleton had lost its ear-bones, seemed to feel no doubt that it was the skeleton 

 of the whale the ear-bones of which I figured. 1 have never seen the skeleton 

 myself, for when I was in Paris they considered it a duplicate of the one they 

 had set up, and not worth my seeing. I think it better to I'etain the name 

 of Neohalmna for this genus. The genus Caperea, though first established on 

 the ear-bone of this genus, has had its character enlarged by the study of 

 the Paris skeleton, and it would produce less change of name to i-etain Caperea. 

 for the whale the skeleton of which is at Paris, otherwise we should have 

 to form a new name for that genus ; but, doubtless, some person wishing to 

 append his name to a new-named old genus, will give it a new appellation. 



As the specimen in the Paris Museum has lost its ear-bones, M. Yan 

 Beneden has added to the figure of that skeleton the figure of some ear-bones 

 said to come from New Zealand, in the Belgian Museum. Now, as there 

 are at least two Black, or Right Whales, with very difierent shoulder-blades, 

 that inhabit the coasts of New Zealand, it is not possible to say to which of 

 these species the specimens figui-ed by M. Yan Beneden belong. 

 2. Euhaloina australis. 



There are at least two Black Whales in New Zealand, and, as yet, I have 

 no evidence that the Eubalcena australis has been taken in New Zealand seas. 

 It is doubtful to which of the two Bight Whales the animal figured by 

 Dr. Diefienbach really belongs. I applied to that figure the name of Bahnna 

 antipodarum (Diefienb. New Zeal., t. 1), and Balcena antarctica (Yoy. Erebus 

 and Terror, t. 1); but as this has been applied to the skeleton of the New 

 Zealand whale in the Paris Museum, by M. Milne-Edwards, Professor 

 Lilljeborg, myself, and M. Yan Beneden in the Ost. Cctaces, I believe it 

 will be better to retain it for that species ; the form of the blade-bone, which 

 is different from that of all the other Eight Whales known, is not likely to 

 be connected with a change in the external form of the animal.
