Hector. — Notes on Ihe Whalrti af iJie Nov Zeahtinl Sea>i. 337 



Francisco, and Avliicli I have reason to tliink was that of the whale referred to 

 in Professor Cope's descrii^tion ; hut only a very cursory examination could 

 he made of this skeleton while I was packing it for transmission to the 

 British Museum, where it is now deposited. 



5. — Bal^noptera huttoni. 



BalcEHoptera Imttoni, Gray ; Ann. and Mag. Nat. Hist., XIII., 450. 

 Physalus antarcticus, Hutton ; Ann. and Mag. Nat. Hist., XIH., 316. 



This is the pike whale of the southern seas and is hardly distinguish- 

 able from the northern Balcenoptera rostrata. The genus Balcenoj^tera is 

 here restricted to the small rorquals, which have less than 50 vertebrae and 

 11 pairs of ribs. The type of B. huttoni is in the British Museum, but was 

 not mounted when I examined it. The second and thu'd cervicals show 

 marks of adhesion, and specimens of thesi vertebrse in the Colonial Museum 

 are as firmly anchylosed as in B. rostrati'. 



6. Physeter macrocephalus, Linn. 



Catodon australis, Gray ; Cat. S. andW.,206; Hector, Trans. N.Z. Inst., V., 158. 



Meganeuron krefftii, Gray ; Cat. S. and W., 387. 



Catodon colneti, Gray ; Cat. Cetac. B.M., 52. 



Physeter polycyphus, Q. and G. ; Uran. Mamm., t. 12. 

 The sperm whale is ubiquitous in warm seas and occasionally roams into 

 high temperate latitudes. It is represented in almost every museum by 

 fragmentary or complete skeletons presenting variations due to age, but 

 there appears to be no ground for distinguishing more than one species 

 which has the name originally given by Linnaeus. 



7. KOGIA BEEVICEPS. 



Physeter irevicejps, De Blainville ; Ann. d'Anat. et de Physiol., 1838, II., 337. 



Kogia breviceps, Gray ; Cat. B. M. Cetacea, 1850, p. 53. 



Physeter simus, Owen ; Trans. Zool. Soc, VI., 30. 



Euphysetes grayi, Macleay ; Gray, Supp. Cat. S. and W., 392. 



Kogia macleayi, Gray ; Cat. S. and W., 218. 



Euphysetes macleayi, Krefft ; Proc. Zool. Soc, 1865. 



Euphysetes pottsii, Haast ; Trans. N.Z. Inst., VI., 97. 



? Kogia floweri, Gill ; Amer. Nat., IV., 738. 

 This very remarkable and diminutive form of the PhyseteridcB has pro- 

 bably a similar range to the sperm whale, but only one instance is recorded 

 of its occurrence north of the equator. Professor Gill describes a specimen 

 from Mazatlan on the coast of Mexico, which is probably the same si^ecies. 

 The other specimens have been taken in the seas off the Cape, Australia, 

 and New Zealand, and there does not appear to be any reason for making 

 several distinct species, as the only complete skeletons agree in all 

 essential characters.
