286 Mr. T. Ayres on the Ornithology of Transvaal. 
Acrocephalus BjEticatus (Vieill.). South-African Reed- 
Warbler. 
This species leaves Transvaal in April, 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). Southern 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 rtjstica, 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
