122 On new Birds from Eastern Africa. 



Hartlaub is right. The primaries are distinctly stated to 

 be " anguste albido margiuatis ; '' and this is the character of 

 G. ccesius, for in G. purus the quills are externally slaty grey 

 like the back. 



13. Gymnobucco cinereiceps, sp. n. 



Brown above and beneath^ with paler brown margins to 

 the feathers ; wing-feathers brown ; tail blackish ; head 

 entirely dark slaty grey ; throat lighter ashy grey, as well as 

 the sides of the neck j two frontal tufts of dark sandy colour ; 

 the forehead streaked with straw-yellow. Total length 

 7 inches, culmen 0*85, wing 4, tail 2'4j tarsus 0'9. 



Hab. Mount Elgon. 



This species differs from the true G. bonapnrtii in its 

 much larger size and grey head and neck. I think that 

 Mr. Bohndorff's skin from Sassa in the British Museum is 

 probably referable to G. cinereicep%, but the specimen is 

 young and difficult to determine. • 



14. Trachyphonus elgonensis, sp. n. 



Purplish black : wings and tail black, with a large white 

 patch on the inner Aving-coverts ; forehead and crown dark 

 crimson, continued down the sides of the neck ; ear-coverts 

 and cheeks black, washed with crimson ; throat and fore 

 neck black, each feather tipped with ashy grey ; breast and 

 abdomen bright lemon-yellow, separated from the spotted 

 throat by a band of bright crimson; sides of body black, 

 largely spotted with yellow ; under wing-coverts white. 

 Total length 9 inches, culmen 0'9, wing 4, tail 3"8, tarsus 

 1-05. 



Hab. Mount Elgon. 



This is very closely allied to T. purpuratus of Gaboon, but 

 nevertheless appears to be worthy of distinction, as it is 

 smaller, with a much smaller bill, and has a much 

 brighter crimson wash on the forehead : the crimson 

 border to the black of the sides of the neck and throat is 

 also very much brighter than in the Gaboon species.
