Since I communicated to the Society my list of the species of 

 Cercopitheciis, at our meeting on March 14th (see above, p. 243), I 

 have paid a visit to the Zoological Museum at Florence, under the 

 care of Prof, Giglioli, and have had an opportunity of seeing 

 specimens of Cercopitliecus bontourh'nii (see above, p. 256) belonging 

 to that Institution, — one of the species of which I had not pre- 

 viously been able to examine examples. Prof. Giglioli has lately 

 been persuaded by his friends to reunite this species to C, albo- 

 gularis, Sykes^; but alter examining the typical specimen and 

 another one subsequently received, I have come to the conclusion 

 that C. boutourlinii is quite distinct from O. alhogularis. 



The original specimen of C. houtourlinii was a female, received 

 from Dr. Traversi in 1887, and stated to have been obtained in 

 Kaffa (a province of Abyssinia to the south of Shoa) in 1885. 

 It is in very imperfect condition, as Mill be seen on inspection of 

 the photographs which I now exhibit. 



The second specimen is a male, obtained by Dr. Traversi at 

 Abugifar in Gimma^ in 1887 and received at Florence in 1889. 

 From these specimens I have drawn up the following description 

 of this species.

(S . Body-hairs long and rough ; upper surface black, with pale 

 fulvous annellations, except on a line between the shoulders which 

 is nearly black ; ears nearly nude, with an inner hairy pencil ; 

 nose, upper lip, chin, and throat white; rest of under surface and 

 limbs and tail black, except the base of the tail, which has annel- 

 lated hairs like the back all round. Total length of body about 21 

 inches, tail 24 inches, together 45 inches. 



2 . Smaller, nearly similar, but less annellated on the back and 

 the head.
