GLOBICEPHALUS MACRORHYNCHUS Gray. 



Globiocephalus macrorhynchns, Gray, Zool. Erel)us and Terror, I84{], p. 33; Cat. 

 Seals aud Whales, 1866, p. 320. 



This species is founded on a single skull, No. 3000, in the Royal Col- 

 lege of Surgeons, London, to which institution it was presented by 

 F. D. Bennett. The locality from which it was derived is unkuown. 



I regret to find that I made no notes upon this skull aud have only 

 my measurements for comparison. As the skull is a youngish one I do 

 not trust myself to draw any conclusions from the consideration of the 

 measurements alone. 



In his paper on the Delphinidm, Professor Flower is inclined to believe, 

 though with some hesitation, that the blackfish skulls with broad inier- 

 maxillte all belong to the same species. I have since satisfied myself, 

 however, that tw^o forms, G. brachypterus Cope and G. scammoni Cope 

 are perfectly distinct, and the question now arises whether either of 

 these species is identical with G. macrorhynchuH. As I neglected to take 

 notes upon the type-skull, I am, unfortunately, unable to throw any 

 light on this question. The measurements which I took are subjoined :
