In the collection received in 1883 from Dr. Emin Bey (I 
prefer retaining this pseudonym for the present), the last 
which has reached me, and of which I am preparing a de¬ 
tailed account, there is a single specimen of a Tympanistria, 
which, at first sight, struck me from the total want of the 
fine metallic wing-spots so very conspicuous in T. bicolor . 
The specimen being a fully adult male, this was a most 
interesting differential character. I have been able to exa¬ 
mine a large number of specimens of T. bicolor , a species not 
rare in collections, besides which I have gone through all 
the descriptions of this bird published by ornithologists 
(Heuglin, Barboza du Bocage, Sharpe, Shelley, &c.). No¬ 
where do I find a specimen mentioned in which these metallic 
wing-spots (of a more or less bluish or /greenish shade) have 
been wanting. Therefore I feel justified in proclaiming 
this species from Eastern Equatorial Africa as a new 
one. 
The other differences from the common T. bicolor , which 
is not different from T. fraseri , Bp., are less important. In 
most of the specimens of T. bicolor the inferior part of the 
back shows two irregular bands of a darker colour. But 
this is not quite constant, and the two bands vary much in 
distinctness. Thus, for instance, in a specimen from Gaboon 
in the Bremen collection I can discover only one band. The 
ground-colour of the inferior part of the back is, in many 
specimens, rather greyish, in others it is not to be distin¬ 
guished from the colour of the upper part of the back. In 
my new species the ground-colour of the whole upper parts, 
rump and upper tail-coverts included, is a uniform olive- 
brown, with a very faint bronze gloss. Then there are some 
irregular dark spots, forming a sort of transverse band.
