A very imperfect skull in the Museum from the Swainson collection agrees 

 with the above dimensions and characters as far as can be ascertained. A 

 large light-coloured porpoise is not uncommon at certain seasons in Blind Bay, 

 which may perhaps be this species. 



GLOBIOCEPHALUS MACRORHYNCHUS. 



Ne"w Zealand Black-fish. 



G. macrorhyncJius, Gray, I.e. 320. 



Teeth § — |- ; head very much swollen, thick, square, and short j snout blunt; 

 teeth, sub-cylindrical ; angles of the lip curved upwards ; body clumsy and 

 terminates abruptly ; colour uniform black ; skull broad ; beak wide, nearly 

 as broad at the middle as at the notch ; intermaxillaries expanded to cover 

 nearly the whole upper surface. 



Total length 16 to 20 feet. (Gray.) 



Two skulls in the Colonial Museum, prepared by Dr. F. Knox ; length 

 26 inches; height of occiput 14 inches ; length of beak 15 inches, and width 

 at notch 11 inches. 



Five cervical vertebrae anchylosed. 



The Black-fish visit the coast in large schools, and occasionally run into 

 shallow bays, where they get stranded, and fall a prey to the natives and 

 settlers. They yield from 30 to 35 gallons of inferior oil, but are not killed 

 without some risk, as they occasion a sickness or vertigo to those who slaughter 

 them, which has sometimes been attended with fatal results. (See Trans. 

 N.Z. Inst., I., 44.) 



EPIODON CHATHAMIENSIS. 



Goosebeak Whale. 



PI. lY. and Y.
