CERCOPITHECUS BÜTTIKOFERF. 57 



(eight specimens) : adult and young , males and females , 

 sent over from Liberia by Messrs. Biittikofer and Sala, 

 agreeing in all respects with C. petaurista from the Gold- 

 Coast , except the black band running from ear to ear round 

 the vertex; of this band we find no trace in the Liberiau 

 specimens. The constant absence of this so characteristic 

 black band obliges me to give a new name to the Libe- 

 rian specimens. The differences in the skulls are too im- 

 perceptible as to allow a comparative description ; the num- 

 ber of vertebra and ribs in the skeletons is the same.
