the crown, but remain of the same huffy white on the eye- 

 brows and feathers bordering the ear-coverts. On the back 

 and sides of the lower neck the pale margins to the feathers 

 are only indicated towards their tips, and form obscure pale 

 brown spots, which become almost obsolete on the mantle. 

 Lower back and upper tail-coverts uniform brown, of a less 

 ashy shade than in C. plebeius and C. jardinii. AVings 

 and tail dark brown. Lores, cheeks, and ear-coverts black. 

 Chin white, with broad subterminal black bars ; throat dusky 

 brown, with broad pale buff ends to the feathers ; remainder 

 of the underparts brown, less dusky than the throat, and 

 slightly shaded with rufous towards the abdomen and under 

 tail-coverts ; the chest-feathers have pale shafts and partial 

 huffish edges, more inclining to shaft-spots than on the throat. 

 Under wing-coverts incline to rufous-buff, and the inner 

 margins of the quills are partially of that colour. Bill black ; 

 legs dark brown ; " iris golden yellow " {Dr. Fischer) . Total 

 length 8'7 inches, culmeu 0*8, wing 3-9, tail 4, tarsus 1-25. 



The type is labelled '' ^ , Mombassa, 23,7,77, Dr. Fischer," 

 and has been incorrectly referred on the label to C. kirki. 



C. reinivardti, Swains., appears to be its nearest ally, from 

 which it maybe distinguished by not having the crown uniform 

 black, by the absence of dark centres to the feathers of the 

 throat, by the darker colouring of the abdomen, thighs, and 

 under tail-coverts, and by its smaller measurements. 



I add a revision of the key to the genus Crateropus as 

 restricted by Mr. Sharpe (Cat. B. Brit. Mus. vii. p. 469).
