In B. chrysocoma [=B. c. guineensis Reichenow, Vog. Afr. ii. p. 149 (1902)] the 

 wing measures 2'2 inches ( = 56 mm.). 



[This small Barbet was found only at the south end of Ruwenzori among the rather 

 dry acacia-forest on the plains, and in the wooded valleys of the lower part of the range. 

 It was not very plentiful. — B. B. If".]

a. 2 . Mpanga Forest, Fort Portal, 5000 ft., 22nd Sept. [No. 3G07. B. B. IF.] 



Iris crimson ; bill yellow ; feet greenish-grey. 



The most important character by which this form may be separated from examples 

 of typical T. purpuratus Verr. has been omitted in the original description, the light 

 streaks on the fore-neck and upper chest being much less numerous and not nearly so 

 pale in T. elgonensis. This character is very marked when series of the two forms 

 are compared. The bill is certainly somewhat smaller ; but the size, the crimson 

 wash on the forehead (though a little brighter in the type-specimens), and the crimson 

 bolder to the black of the throat are the same in both species. 



[A single specimen of the Elgon Barbet was shot out of a small flock of six or seven 

 birds in the Mpanga Forest, but that was the only occasion on which the species was 

 seen.— B. B. IF.]

c. 6 . 50 miles N.W. of Fort Beni, 3000 ft., 15th August. [No. 2451. G. L.] 



Iris crimson or dark red ; bill yellow, red at the tip; feet black. 



[The Great Crested Touraco was common in the Congo Forest and also in the 

 Mpanga Forest, but it was not seen on the mountains. 



The beautiful deep sonorous " cum cum cum" of this bird resounding through the 

 silent depths of the woods is one of the most impressive and characteristic sounds of 

 the great Congo Forest. 



The native (Swaheli) name for several species of Touracos is " cum cum." — B. B. W.~\
