346 ZOOLOGICAL EESULTS OF THE EUWENZOEI EXPEDITION. 



outer tail-feathers marked as in L. congicus. Of tiie two adult males from Eastern 

 Ruwenzori, one must be referred to typical L. humeralis and the other to L. congicus, 

 if the difference in the markings of the tail-feathers is to be regarded as of subspecific 

 value, but it seems doubtful if this character is of any great importance. It must, 

 hovTever, be added that in the British Museum there are no specimens from the 

 Congo district for comparison. 



[A few examples of the Eastern Fiscal-Shrike were seen on the east side of Euwen- 

 zori, but were not met with above an elevation of 5000 ft. — B. B. PF.]

 Iris cream-colour, yellow, or light brown ; bill black, basal part of the lower mandible 

 white or pale slate-colour ; feet varying from slate-blue to dark grey. 



The two subspecies of this large Grass-Warbler have already been discussed at some 

 length in my paper on the birds from the Sobat and Baro Rivers quoted above. The 

 splendid series procured by the Expedition, and representing the greater part of the 

 year, includes several immature examples. These may be recognized by the narrow 

 sandy margins to the feathers of the occiput, nape, and mantle, as well as to the 

 secondary quills, but in other respects the plumage is similar to that of the adult. 



[This species was seen at Entebbe and throughout the journey to Ruwenzori. It was 

 not uncommon at the north and south ends of the range and was also met with in the 

 Semliki Valley, but it was never seen on the mountains. — B. B. W.']
