The note is loud and shrill, totally unlike that of Turacus emini, which has a low- 

 toned musical " curung curung" repeated over and over again. 



Although chiefly to be met with in the Podooarpus trees, birds might now and then 

 be seen perched on the end of a long bamboo. Like its ally, T. emini, it was far more 

 often heard than seen, and it was some weeks before we identified the shrill laugh so 

 often heard among the bamboos as the voice of Johnston's Touraco. — R. B. W.~\

feet black. 



[The forest in the central part of the Semliki Valley on the west of Ruwenzori is 



undoubtedly the headquarters of Emin's Touraco, and there it was extremely numerous. 



It was seen throughout the eastern parts of the forest, and westwards as far as 



Basoko, and was not uncommon in the Mpanga Forest. 



On Ruwenzori it was fairly common throughout the forest-zone, and was seen 



up to an altitude of about 9000 ft., but above this its place was taken by Gallirex 



johustom. The Touracos run so last and so nimbly along the boughs of the trees 



that they appear more like squirrels than birds. They were always difficult birds to 



procure, and were far more often heard than seen. — B. B. W.]

Both these examples belong to the darker-backed southern form with brown inner 

 secondaries, which has very properly been separated by Prof. Neumann from C. monachus 

 Riipp., from Abyssinia.
