PYRENESTES 281 
Shelley’s Crimson-wing inhabits the Ruwenzori Mountains 
of Central Equatorial Africa. 
This is the second good new species of the genus discovered 
by Mr. Jackson during the recent expedition to Ruwenzori. 
The type, an adult male, was procured for him in that mountain 
range, February 22, 1902. I appreciate the kindness of my 
friends, Mr. Jackson and Dr. Sharpe, in naming this remarkably 
fine species after me.
