272 MESSRS. O. THOMAS AND H. SCHWANN ON [Apr. 18, 



A short table of comparative skull-measurements will serve to 

 show the distinctness of the Zululand form, v/hile the ISTamaqua- 

 land race may be distinguished at once by the great size of the 

 ears.

It is perhaps worth mentioning that in the type of L. s. 

 onegalotis the small postei'ior molar m^ is wanting on both sides 

 of the upper jaw. This abnormality occurs, according to the 

 observations of Dr, Forsyth Major, more frequently in Hares of 

 this species than in any other, 



" Zulu name, ' Gwaja,' Rather scarce, oAving to the continuous 

 persecution of the natives with traps and snares."^ — C H. B, G,

This fine Hare, which we have named in honour of Mr, Rudd, 

 has a somewhat complicated history, owing to a confusion between 

 it and the true P. crassiccmdatus Geoff, 



In 1832 the latter species was described on a specimen from 

 " Port Natal " still in the Paris Museum, This typical specimen 

 is mounted, and has its skull still in the skin, whence none of the 

 successive Directors have thought fit to have it extracted. 



In 1853 the British Museum received from the Zoological 

 Society's Museum a Pronolagus which was determined as P. crassi- 

 caudatics, and remained the only adult representative of the group 

 until comparatively lately. It was therefore always treated as 

 being the true crassiccmdatus, as, for example, in Thomas's paper * 

 describing Oryctolagus c, nyikce and curryi, where its hind foot 

 and cranial lengths are quoted as being those of Geofiroy's 

 animal,
