This species is most nearly allied to T. johnstoni Shelley, which it resembles in 

 having the outer webs of the secondary-quills margined with olive ; but it is easily 

 distinguished by the conspicuous orange-yellow rump and upper tail-coverts, and by 

 having the yellow on the second pair of tail-feathers confined to the basal half of the 

 outer web, and the outer pairs widely tipped with black, about - 7 inch in width. 



Iris dark hazel; bill black; feet olive-brown or greenish-brown.

Specimen No. 3141, a male shot by Mr. Woosnam at 11,500 ft., is a very richly- 

 coloured bird, the mantle and back being of a more reddish-olive colour than in any 

 other specimen, and the breast and sides of a deeper orange-yellow. 



Immature birds of this species have the head, mantle, chest, and breast spotted, the 

 feathers of the upperparts having a buff spot margined with black at the extremity, 

 while those of the underparts are pale yellow bordered with black. The belly is pale 

 yellowish-white. The outer tail-feathers are quite differently marked from those of 

 the adult, being orange-yellow, bordered on both webs at the extremity with black, 

 whereas in the adult the whole terminal portion of the feather is black. 



Mr. (Jarruthers obtained an adult male example of this species on the Mufumbiro 

 volcanoes. 



Dr. Reichenow has recently re-described this species under the name of Tarsiger 

 eurydesmus. 



Two eggs of T. ruwenzori were procured in the Mubuku Valley, at an elevation of 

 8000 ft., on the 23rd of January. They are of a rather pointed oval shape and slightly 

 glossy. The ground-colour is white, finely freckled all over with light red and lilac- 

 grey, the markings being most numerous towards the larger end. They meauure 

 •91X-61; -9X-62 inch. 



[The Ruwenzori Bush-Robin was met with from an altitude of 6500 ft. up to 

 12,000 ft. It was most numerous in the forest and in the lower part of the
