ward of Latakoo, that place which the latter holds to the 
southward.” Stark and Sclater, in their ‘“ Birds of South 
Africa” (ii. p. 9) write: “It is common in Griqualand West, 
and according to Dr. Bradshaw is very abundant along the 
Orange River in the neighbourhood of Upington, a locality 
in which ZL. collaris occurs. “A clutch of three eggs was 
taken by Mr. A. F. Ortlepp on October 15, 1884, at Du Toits 
Pan (¢.e., Kimberley); these eggs closely resemble those of 
L. collaris, measuring about 0°90 x 0°70.” 
In the Transvaal specimens have been collected by Dr. 
Rendall in the Barberton district and by Mr. T. Ayres at 
Potchefstroom. From the latter place Dr. Bowdler Sharpe had 
one killed in March in his own collection, and another, a fine 
adult female obtained in May, 1879, formed part of my own 
collection. On comparing this specimen with a fine series 
of F’. humeralis I then had of Colonel A. EK. Butler’s collecting 
at Newcastle in Natal, I found that several of the latter had 
the forehead and eyebrows mottled with white, as if the two 
forms were liable to interbreed, and I have found this to be 
also noticeable in other South African specimens obtained 
near where the range of these allied species meet. 
This is confirmed by most observers in the field. Short- 
ridge noticed it at Hanover in northern Cape Colony and Clarke 
states that he actually found a female F’. collaris breeding 
with a male F’. swhcoronatus at Bloemfontein in October. 
In the British Museum there are many intermediate forms 
between I. collaris, F'. humeralis and F’. swbcoronatus, chiefly 
from the Orange Free State and the Transvaal. 
From Bloemfontein there is a female with a fairly well- 
marked eyebrow, some white on the rump, hardly any on the 
secondaries and grey freckled under-parts, on the whole 
referable to F’. swbcoronatus, but with traces of F. collaris. 
This example was collected by Clarke, August 17, 1901.
