Trachijphonus erythrocephalus , Shelley, Ibis, 1885, p. 39-i 

 (nee Cab.) . 



As Capt. Shelley had not been able to examine the type 

 of TrachypUonus erythrocephalus in the Berlin collection, it 

 is easy to understand that he believed the Somali specimen 

 to be identical with the above-named East-African species, 

 discovered b}^ Mr. T. M. Hildebrand at Kitui, a locality in 

 Ukamba. The two birds closely resemble each other, the 

 style of coloration being the same in both ; but there cannot 

 be the slightest doubt about their specific difference. The 

 differential characters are the following : — 



1. The new Somali species is more distinctly crested than 

 Tr. erythrocep}halus, in which, however, this character is not 

 altogether wanting. 



2. The Somali bird is decidedly smaller, as the following 

 measurements will show : — 



3. The white spots on the mantle, scapulars, and wing-

 bird, whereas they are yellowish white in Tr. erythrocephalus. 



4. The shape of these same spots is subtriangular in the 

 Somali bird, round and drop-like in TV. erythrocephalus. 



5. In this latter species the bright red colour of the head 

 occupies the whole of its sides, broadly bordering the black
