262 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 Mesoplodon 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. 

 Ziphiiis 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 

 I'urner in the " Proceedings " of the Royal Society of Edin- 

 burgh for 1872. 



THE DOLPHINS AND PORPOISES. 

 FAMILY DELPHINID^. 



The wh )le of the remaining British representatives of the 

 Cetacean Order are included in the Family Delphinidce^ most 

 of the members of which are distinguished from the 

 Physeteridce. by the presence of numerous teeth in both jaws,
