males a little siiinller relatively tliaii in maxweUi ; sexual 

 cli.^parity less mavked tlian in the latter. 



Coloration and external cliaracters, apart from smaller 

 size, exactly as in C. lowei ; size, iE anything, less than in 

 maxiveUi. 



Skull consj)iciiou~ly differing from those of other members 

 of ti)e group in the unusually small nasals. In both sexes 

 these bones are shorter ami narrower, absolutely and rela- 

 tively, than in either maxwelli or lowei. In liheriensis there 

 is a sexual difference in this respect, the males having nasals 

 as large as, or larger than, in loivei and maxwelli, while in 

 the feniales these bones approach those of danei. Maxillary 

 tooth-row intermediate in relative length between lowei and 

 maxwelli, the molar series being relatively longer than in 

 either. 



llemarls. — T have much pleasure in naming this interesting 

 dniker after Captain A. M. Dane, of H.M.S. 'Dwarf,' to 

 whom Mr. Lowe was indebted for much hospitality and active 

 assistance during his trip to Sierra Leone.
