378 ZOOLOGICAL RESULTS OF THE RUWENZOR1 EXPEDITION. 



Iris white ; bill black ; feet black or brown. 



[Both Kirk's and Sharpe's Babbling-Thrushes were seen throughout the journey from 

 Kntebbe to Ruwenzori. They were very common birds in the acacia-country at the 

 south end of the range and in the upper Semliki Valley. They were always observed 

 going about together in noisy parties, and were very inquisitive. — R. B. W.]

 Type of species.'] 



Czarnikow's Babbler is most nearly allied to P. lohndorffi (Sharpe), but differs in 

 having the forehead, fore-part of the face, and the chin black ; the feathers of the 

 crown blackish, with grey margins ; and the chestnut of the upper- and underparts 

 darker in colour. Iris claret-colour ; bill pale yellow ; feet pale greenish-grey. 



Total length ca. 8-5 inches ; culmen 1-05; wing 46 ; tail 32; tarsus T45. 



Iu the type of P. lohndorffi, which is no doubt an immature bird, the feet are 

 whitish (in the dry skin). 



Mr. Alexander procured three examples of this species on the Welle River. 



[The type-specimen of Czarnikow's Babbling-Thrush was obtained in the Congo 

 Forest, and was the only one seen. It was shot among the dense undergrowth. — 

 R. B. W.]

 Iris yellow, dark brown in the immature male; bill black ; feet grey or bluish-ash. 

 There can be no doubt that, as has already been suggested by Dr. Sharpe, M. zenkeri 



is founded on immature examples of M. flavicans. In addition to the young male 



(specimen c) mentioned above, there is an immature female in the British Museum 



procured at Efulen, Cameroon, by Mr. G. L. Bates, which agrees exactly with the 



description and figure of M. zenkeri given by Dr. Eeichenow. 



[This Long-billed Bush-Warbler was seen only in the Congo Forest, where it was not 



uncommon. It was usually observed climbing about among the tangled masses of 



creepers which hung from the trees. — R. B. W .]
