cap and including the eyebrows ; in the Somali specimens 

 the red colour is restricted to a much smaller space^ the eye- 

 brows, margin of the forehead, and remainder of head and 

 neck being yellow, shading into a lighter red on the nape, 

 ear-coverts, and hinder portion of the cheeks. The silk- 

 white ear-spot is the same in both birds. 



6. The black longitudinal mark running down the middle 

 of the throat is very narrow and rather irregularly shaped in 

 the Somali bird ; it is fully and regularly developed and 

 increases in breadth towards the lower end in Tr. ery- 

 throcephalus. 



7. The white spots and bars of the black tail-feathers are 

 differently shaped in the two species, being much more 

 regular and on a smaller scale in the Somali bird. 



The only specimen of Tr. shelleyi obtained, was shot by 

 Mr. Lort Phillips on the plateau of the interior of Somali- 

 land. Three others were seen by him. 



The well-defined and exclusively African genus Trachy- 

 phonus comprises two groups, in which the style of colora- 

 tion is rather different.
