FISCUS MARWITZI 257 
Another from the Tweeddale collection from the same place has 
all the characters of F’. humeralis, but for a small spot of white 
at the lores. A third, also a female from Bloemfontein, dated 
June 15, 1903, obtained by Messrs. Woosnam and Dent, is 
indistinguishable from the typical . collaris of Cape Town. 
A female from Vredefort Road Station (Barrett Hamilton) is 
an undoubted F’. humeralis, while two males from Kroonstad 
have traces of the white eyebrow. 
To sum up, the Coroneted Fiscal Shrike has its centre of 
distribution in German South-West Africa. Where its range 
meets that of Ff. collaris and F’. humeralis it interbreeds, and 
intermediate forms are as prevalent as those apparently true 
to type. 
The British Museum contains typical examples of this 
species from Koys Fountain in Great Namaqualand and from 
Otjimbinque and Swakop River in Damaraland (Andersson), 
from the Hart River in Bechuanaland (Jameson) and from 
Kuruman (Woosnam); examples of F. collaris x F. sub- 
coronatus from Bulls Port in southern Great Namaqualand 
(Andersson) and from Bloemfontein (Clarke); of EF’. humeralis 
x F. subcoronatus from Maribogo on the Vaal River in north 
Cape Colony (Woosnam), from Bloemfontein and Kroonstad 
in the Orange Free State, and from Salisbury and Mount 
Chirinda in southern Rhodesia (Swynnerton).
