than in females of C. maxwelli. Females hornless, but one 

 specimen with minute traces of horn-cores 2 or 3 mm. in 

 height. General outward appearance and colour as in 

 maxwelli. Size slightly larger, the extreme length of 

 skull being about 150 mm., instead of about 140 mm. 



For skull-measurements see table at p. 532. 



Range. — Liberia. At present known from Mount Barclay 

 and from a spot "50 miles inland from Monrovia." 



Whether Pel's specimens from Dabacrom, Gold Coast, 

 described by Temminck under the name maxwelli y belong to 

 the present species or to another unnamed form cannot be

 material. Temminck describes the cars as " portent de larges 

 bordures blanches le long de leur contour interne " ; he says 

 that the female differs from the male only " par de tres-petites 

 cornes, souvent obtuses, ou commes perdues, et cachcos dans 

 les touffes, d'ou elles prennent naissance."
