282 LLOYDS NATURAL HISTORY. 



GENUS ZIPIIIUS. 

 Ziphius, Cuvier, Ossemens Fossiles, 2nd ed. vol. v. p. 352 



(1823). 



This genus of Beaked Whales, apparently represented only 

 by a single species, may be distinguished from Mcsoplodon by 

 the characters of the skull, and the circumstance that the 

 single pair of lower teeth, which are directed upwards and for- 

 wards, are placed at the anterior extremity of the jaw. 



CUVIER'S WHALE. ZIPHIUS CAVIROSTRIS. 



Ziphius cavirostris, Cuvier, Ossemens Fossiles, 2nd ed. vol. v. 



p. 352 (1823); Bell, British Quadrupeds, 2nd ed. p. 428 



(1874); Southwell, British Seals and Wales, p. 102 



(1881) ; Flower, List Cetacea Brit. Mus. p. 10 (1885). 



This exceedingly rare Cetacean is so little known that 



neither its characters nor distribution can be given with any 



approach to exactness. From the circumstance that it has been 



met with in regions so remote from one another as the Shetland 



Islands and New Zealand, it is probable that it has a nearly 



cosmopolitan distribution, although not ranging into the Polar 



seas. 



The single British example of Cuvier's Whale hitherto 

 recorded was taken off Hanno Voe, to the north-west of the 

 mainland of Shetland, and has been described by Sir William 

 Turner in the " Proceedings " of the Royal Society of Edin- 

 burgh for 1872. 



THE DOLPHINS AND PORPOISES. 

 FAMILY DELPHINID.E. 



The wh >le of the remaining British representatives of the 

 Cetacean Order are included in the Family Delphinida, most 

 of the members of which are distinguished from the 

 Physeterida by the presence of numerous teeth in both jaws,
