286 Mr. T. Ayres on the Ornithology of Transvaal. 



AcROCEPHALUS B^TicATUS (Vieill.) . South-Afiican Reed- 

 Warbler. 



This species leaves Transvaal in Aprils and appears again 

 with other migrants in our early spring. I am more in the 

 swamps and amongst the reeds in our winter than in summer, 

 but have never met with one of these Warblers in winter, 

 either amongst sedges, reeds, or hedgerows, where in summer 

 they are plentiful ; neither is it found in winter in the more 

 northern and warmer districts of Transvaal. The nests of this 

 species vary a good deal in size and appearance, some in fact 

 look as if they had been added to year by year, though this 

 could scarcely be so. 



CiNNYRis MARiQUENSis (Smith). Southcm Bifasciated 

 Sun-bird. 



These Sun-birds are found very sparsely on the Limpopo 

 river during our winter months, feeding amongst the aloes 

 which grow plentifully on the dry stony ridges ; the males 

 frequently fight and chase each other about with much 

 vigour, although it is not the breeding-season. 



HiRUNDO RUSTiCA, Linn. Chimney Swallow. 



Male and female, Potchefstroom, 12th January, 1885. 



I found these Swallows, mostly young birds, congregating 

 on the mimosas in company with H. cucullata. 



[Both specimens sent appear to be birds of the previous 

 spring, in course of change into adult dress. — J. H. G.] 



MuscicAPA GRisoLA, Linn. Spotted Flycatcher. 

 Potchefstroom, 12th January, 1885. 



The Spotted Flycatcher is a regular summer migrant to 

 Potchefstroom, though by no means in great numbers. 



Pachyprora molitor (Hahn & Kiist.). White-flanked 

 Flycatcher. 



This is a very scarce species on the river Limpopo ; I saw 

 but two, both solitary, during the two winter months which 

 I spent in that locality. 



[Mr. Ayres has sent a specimen, evidently a male, and so 

 marked by him, in which both ends of the pectoral band are
