8 CATALOGUE OF UNGULATES 



Eange co-extensive with that of the genus. 



The following races have been named, but some of these 

 are very closely related, and so imperfectly defined, that a 

 complete " key " cannot yet be drawn up : — 



A. No dark blaze on lower part of face. 



a. Horns medium ; generally from about 18 to 



20 inches in a straight line ; colour duller... M. m. melampus. 



b. Horns very small, frequently not more than 



1 4 inches in a straight line ^. m. johnstoni. 



c. Horns still smaller M. m. Jcatangce. 



d. Horns very large, attaining in some cases a 



length of from 23 to 25 inches in a straight 

 line ; colour redder ; faint dark marks near 

 eye jS. m. suara. 



e. Larger than last, colour darker ; no dark 



eye-marks jSJ. tn. rendilis. 



B. A dark blaze on lower part of face ^. m. petersi. 



A. — ^pyceros melampus melampus. 



^pyceros melampus typicus, Thomas, Proc. Zool. Soc. 1892, p. 553 ; 

 Ward, Becords of Big Game, ed. 6, p. 227, 1910. 



Typical locality Klipfontein, Little Namaqualand, just 

 south of the Orange Eiver, which apparently marks the 

 southern limit of the species. 



Horns apparently medium in size ; no blaze or other 

 dark markings on face. Basicranial length about 10|- inches 

 (260 mm.). 



How far north this race extends has not been determined, 

 and the reference to it of some of the undermentioned 

 specimens is consequently provisional. 



619, a. Frontlet and horns, Lataku, Bechuanaland. 

 This and another specimen from the same donor were the 

 first examples of the species received at the Museum, and 

 probably in England. The animal to which they belonged 

 was shot in 1812. Presented by Dr. W. J. Burchell, about 1817.
