than in any other species I know ; it is much higher than the base 

 of the horn. In the S2)ecies which Dr. Peters has called C. oltifrons it 

 does not appear to be so high as usnal in the genus. In C. Grimmius, 

 with ascending horns, it is flat between the eyes. The following 

 observation is founded on the comparison of a scries of skulls of 

 males : — The skulls differ in the length of the face, thus : — In C. 

 natalensis the face is short ; the distance from the orbit to the upper 

 end of the intermaxillary bone is shorter than the length of the in- 

 termaxillary bone. In C. Si/lincHltri.v, C. 0'jiU>i/i, and C. ocularis 

 the distance above defined and the length of the intermaxillary are 

 nearly equal. In C. Grimmius they are rather longer. In C. hngi- 

 ccjis the distance from the front edge of the orbit to the tip of the 

 intermaxillary is much longer than the length of the intermaxillary. 

 Dr. Peters figures as the skull of a young female of C. oltifrons 

 a skull of a very different form from that of the skiill with tlie horns 

 of the male above referred to. I have not observed such a difference 

 in the skulls of the females of any of the species oi CephaJophus t^iai 

 have occurred to me. 1 have some doubt if it does belong to the 

 same species, as the figure of the young female animal is very like 

 the skull of a female 0. Grimmius, which, is an animal that has ascend- 

 ing horns iu the male. (Gray, P. Z. S. 18G5, p. 204.) 



1. GRIMMIA. - ^^/^^•/*/>^-. 



Ears elongate, acute, hairy. Horns elongate, slender, more or less 

 erect or ascending, slanting backwards. Fur yellow or grizzled. 

 Nose often marked with a black streak. Skull conical; forehead 

 fiat ; nasal bones oblong, elongate ; intermaxillary bones elongate.

 p. 539. 



Colour variable, probably influenced by geographical considera- 

 tions. In the more southern parts the fur is said to become longer 

 and greyer in winter. 



* Horns elonf/afe, svberecf. SltuU rather sliorf ; the intermaxillaries (in three 

 / xpecimens) rcachiiu/ Just up to the edge of the nasah ; nasal hole mode- 

 fv^ rate, sides nearly parallel ; suborbital pit large, deeply concave.
