direction if the animal had lived to be older." There 

 appear to be six pairs of cartilaginous sternal ribs. 



In the manus the scaphoid and the lunar are united, 

 though a groove remains to mark their original dis- 

 tinctness. The cuneiform is partly united with the 

 unciform ; the magnum and the trapezoid are com- 

 pletely united. So far as is known the pelvis consists 

 of only one small bone, 5 '8 inches in length. 



Berardius arnouxi is one of the few whales with a 

 really limited distribution. It has only been taken, so 

 far, on the shores of New Zealand. Malm, however,* 

 has given some account of a fragmentary skull, to 

 which the name B. veg<z has been given, from 

 Behring's Straits, and there is also B. bairdi. 



The genus ZlPHIUS has as characteristic features : 

 the skull with mesethmoid ossified ; the nasals con- 

 joined form an asymmetrical eminence upon the 

 vertex. Two teeth near symphysis of mandible, 

 besides smaller, functionless teeth. Vertebral formula : 

 C. 7 ; D. 9 or 10 ; L. 1 1 ; Ca. 21 =49. The first four 

 cervicals fused, or only three or six. Seven ribs two- 

 headed. Sternum consists of five pieces. Phalanges : 

 I, i. II, 5. Ill, 5. IV, 5. V, 2. (Parker and Scott.)

t An alleged synonym of this species, Epiodon urganantits, of 

 Rafinesque, is rejected by Fischer with the following contemptuous 

 observation : " It would be wise to allow the diagnosis of Rafinesque to 

 repose in peace ; we should not accord any scientific notoriety to such 

 labours ! "
