All these examples differ from spfcimens originating from Abessinia 
(May—July) and East-Africa ,, (Bypemher—May) in the collection of the 
Hungarian National Museum, in their. light tawny-buff coloration on the 
upperpart. I shot many examples, in ^udan, which were all similar coloured. 
One of the most difficult matters is to shed light on the qu^stiop of 
the African species of Prinia ? but it is sure, that the Sudanese birds do 
not agree with the typical specimens, and on the other hand I think they 
are not yet separated in the scientific Ornithology, therefore I proposed for 
this bird the above new name. 
Fam. LANIIDAE.

According to my notes, iris yellowish-white with a yellow outer ring, 
eye-wattle orange-yellow ; feet orange-red. 
I met with these interesting birds just after arrival at Khor-Em-Bul 
and I had opportunity to observe them for a short time. It was a small 
party of six individuals together, they were far enough from me and disap¬ 
peared at once, but were shortly visible again. The birds were continualy 
in flight and never remain at one place by its restless habits, moving and 
flying from thé middle part of a tree always lower down, still above the 
low bushes they hang over with open wings, which was their most character- 
istical habits because the open wings were fluttering up and down like 
butterflies. It seems rearlv like black and white winged big butterflies 
from a considerable distance. I succeeded in shooting two examples of them 
one of which I lost. After shooting the remainder were flying on the top 
of the highest trees and dissapeared soon for good.
