Mr. T. Ayres on the Ornithology of Transvaal. 285 
localities ; buildings suit it well, and were it undisturbed it 
would soon become common in Potchefstroom. 
[The many variations of plumage to which this Wheatear 
is liable may make it desirable to append the following de¬ 
scriptions of two specimens now sent by Mr. Ayres. 
Male, immature, Potchefstroom, 6th January, 1885. En¬ 
tire upper and under surfaces blackish brown (but brownest 
on the abdomen), excepting, however, the shoulder-patch and 
upper tail-coverts, these are white, but the feathers com¬ 
posing the former have their bases and shafts black; the tail 
in this specimen presents the following peculiarities—one 
rectrice of the central pair is black throughout, the other is 
black except the basal moiety of the exterior web, which is 
white, the remaining rectrices are white, but tipped, more or 
less extensively, with black. 
Male, Potchefstroom, 12th January, 1885. In this speci¬ 
men the plumage is black above and below, with the follow¬ 
ing exceptions :—The crown of the head is brownish grey, 
interspersed with a very few apparently newer white feathers ; 
the shoulder-patch resembles that of the preceding specimen, 
but with the white more extended; a few unmoulted feathers 
on the upper surface are dark brown, the newer adjoining 
feathers being black ; the tail, which is in process of moult, 
has the exterior pair of rectrices old and entirely white, the 
other rectrices, which are only partially developed, being 
black, but with white bases to some of the lateral ones; the 
upper tail-coverts and the tips of some feathers of the under 
tail-coverts are white.—J.H.G.] 
Saxicola galtoni (Strickl.). Galton^s Wheatear. 
This species is sparsely distributed on the Upper Limpopo 
river, and also amongst the mimosas in the Potchefstroom 
district. 
Phylloscopus trochilus (Linn.). European Willow 
warbler. 
Male, Potchefstroom, 10th January, 1885. 
This species migrates every year to Transvaal during our 
summer months.
