416 ZOOLOGICAL KESULTS OF THE RUWENZORI EXPEDITION. 



more especially as the feathers are wanting on the sides of the face, and in that con- 

 dition it is scarcely possible to distinguish it from immature examples of T. hirsutum. 

 It must be further noted that younger birds of this group have the spots on the head 

 and back, as well as the margins of the wing-feathers, bright golden ; whereas in the 

 adult these markings are pale lemon-yellow and the crown is uniform black.

Iris dark brown or yellow ; bill and feet black. 



Though some doubt has been cast on the validity of this species by Dr. Reichenow 

 and others, it appears to be well characterised and perfectly distinct from the allied 

 T. lacrymosum Cab. The adults of the present series all agree with the type-specimens 

 from Mulema (Doggett). Younger birds differ from the adults in having the black 

 spots on the sides of the underparts smaller and more oval in shape. No. 3399, a 

 female procured by Mr. Woosnam, is of special interest as illustrating the change of 

 plumage from the immature to the adult. When I compared T. radcliffei with T. 

 lacrymosum I stated that the latter differed in having the underparts washed with buff 

 instead of yellow. This, however, is not a reliable character, for specimens from 

 Mt. Kenya [Delamere), which have since been added to the collection, show that in 

 freshly-killed examples of both species the underparts are washed with yellow. 



[Quite a number of Delme Radcliffe's Barbet inhabited the acacia-forest around the 

 south end of Ruwenzori and the upper part of the Semliki Valley, but they were never 

 seen on the mountains. — M. B. IF.]

This species is most nearly allied to G.peli Haiti., but is distinguished by having 

 the bill black. It approaches G. cincrciccps Sharpe in the colour of the bill and in 

 bavins the feathers of the throat, as well as the basal part of the feathers of the cheM. 

 o-rey. It may be at once distinguished from that species by having the head covered
