This species has the appearance of an Erythrosterna; but the 
colour of its tail separates it from any of the species with which I 
am acquainted ; otherwise it comes into the “ Key to the Species ” of 
Muscicapa in my ‘ Catalogue’ (vol. iv. p. 150) as follows :— 
a. With no white bar on the wing and with no white at base

In travelling over the greater part of this vast Republic, I have 
found the difficulties and dangers great, and the distances to be 
surmounted, from one hunting-ground to another, immense. Not 
only so, but the naturalist here, unlike his brother in Europe, 
receives no encouragement, enjoys uo facilities, and is obliged to
