latter they are entirely brown. In this new form, however, the legs of the oldest 

 mah are qnite brown on the lower half, as in C. s. sakeeii, while on their upper half 

 they are white behind as in C. s. aihirica. 



The three specimens from which this description is made were collected by one 

 of Mr. Carl Hagenbeck's travellers in the Katutay Range of the Altai Mountains, 

 in the winter of 1898—1890.

THIS interesting form of Tiiracus resembles very closely the Bengnela Plantain- 

 eater known as Turacus schalowi (Reichw.) (Jour}i. /. t>/-n. 1891, p. 5 ; Cat. 

 B. Brit. Mus. XIX. p. 439), but differs from the latter in the length and colour of 

 the crest-feathers. These are longer, reaching 112 mm. in the most adult male in 

 the Berlin Museum ; they are slightly widened towards the tip, and are distinctly 

 metallic greenish-blue before the white tip. 



The late Dr. Fischer shot Tiiracus chalcolophus on the Mori river on the east 

 side of Victoria Nyanza, but his specimens were not separated from T. schalowi. 

 Colonel von Trotha obtained it in the Loita Hills in German East Africa, and Oscar 

 Neumann in the forests of Gnrui, about 2000 to 2600 mm. above the sea, in the 

 Loita Hills and on the Ngare Dobasch ; so that it appears to inhabit the forest-clad 

 mountains between the great Masai-ravine and the Victoria Nyanza, to about 1' 

 southern latitude, while farther north, at Sotik and Man, only Turacus hartlaubi 

 has been found so far (cf. Journ.f. Orn. 1899, p. 74). 



According to Reichenow and Neumann tvpical T. licingstoni would only occnr 

 iu the Zambesi region, while birds from German East Africa have been separated 

 by Fischer and Reichenow, who described two new forms, which they named 

 T. reichenoivi and T. hybridus. These latter birds are evidently different from the 

 more southern T. livingstoni, but possibly T. reichenoici and hi/bridus cannot be 

 separated (cf Neumann, I.e.). 



The Tring Museum has received a skin of T. chalcolophus from Mr. Oscar 

 Neumann, and I am at present not aware of any other examples in British 

 collections. 



The plate shows the characteristic points of Neumann's Plautaiu-eater very well.
