Characters.— lntevmedia.te between Pycnonotns layardi fayi and 

 P. I. minor Heuglin. In extreme minor, from Gondokoro on the 

 Bahr-el-Jebel, the head is scarcely darker than the mantle ; in fayi 

 the head is brownish black; in phccocephalus it is dark brown (be- 

 tween sepia and clove brown). The mantle, rump, upper tail- 

 coverts, and flanks are decidedly more olivaceous than in fayi or 

 minor; the abdomen is more huffy white ; the crissum and under 

 tail-coverts are a considerably deeper yellow (lemon yellow instead 

 of canary yellow). 



Measurements of type {adult female). — ^Wing, 92 mm.; tail, 82; 

 exposed culmen, 15 ; tarsus, 21.5. 



Remarks. — This peculiar form inhabits Uganda from Lake Vic- 

 toria to Lake Albert. On the Upper Nile (Bahr-el-Jebel) this form 

 rapidly passes into the subspecies minor.
