DOLPHINS 283 



relatives to wit, squid. The "fish" goes in schools 

 from ten up to hundreds, which sometimes move 

 rapidly, and occasionally lie closely huddled together 

 at the surface. It seems to be unnecessary to state 

 that this whale is called "black-fish," for so many 

 whales are called by this exceedingly obvious name. 

 It is not considered a prize by whalers, for its oil is 

 not abundant. 



Globicephalus brachypteriis, also of Cope,* is in 

 colour entirely black. Teeth, 8. Pre-maxillae greatly 

 expanded anteriorly, covering maxillae. 



This Atlantic species is of the form and size of the 

 Caa'ing whale. It may show a difference in the num- 

 ber of lumbar vertebrae, which are stated at eleven. 

 But the commencement of the Caudal series being 

 marked by the first chevron, which bones are very 

 apt to be lost, it is a little difficult to be certain upon 

 this point. The total number of vertebrae is given 

 at 57, one or two less than the numbers ascertained 

 for G. me las. 



Other reputed species are G. sieboldi, which in 

 Schlegel's drawing has a very different aspect from 

 G. me/as, being of a more slender build with a 

 very falcate dorsal fin ; G. macrorhynckus, of Gray, 

 and of unknown locality and unknown form ; what 

 is known about it is the skull.
