rufous, and with a slight rufous tinge on the centre of the 
otherwise white throat; these peculiarities are probably 
the remains of immature plumage resembling the dress of 
the adult female. A similar stage of plumage has been re¬ 
corded by Mr. Sharpe in the young males of two allied 
species, Platystira cyanea and Pachypr or a senegalensis (vide 
Ibis, 1873, pp. 158 & 164).—J. H. G.] 
Lanius collaris, Linn. Fiskal Shrike. 
Female, Potchefstroom, 26th April, 1884. Stomach con¬ 
tained grasshoppers. 
This Shrike, and also Laniarius silens, is sparsely distri¬ 
buted amongst the mimosa bushes growing on the ridges of 
the Mooi river valley in the Potchefstroom district. 
Enneoctonus collurio (Linn.). European Red-backed 
Shrike. 
Males, immature, Potchefstroom, 6th, 10th, and 16th 
January, 1885. 
The Red-backed Shrike is found in the same localities as 
the two species last mentioned, but is perhaps sometimes more 
plentiful. 
[In all three of the specimens sent the assumption of the 
adult dress has just commenced.—J. H. G.] 
Telephonus senegalus (Linn.). Senegal Tchagra Shrike. 
These Shrikes are by no means uncommon on the river 
Limpopo, and one or two may often be seen amongst a com¬ 
pany of small birds which frequently collect together without 
any apparent cause. [In previous volumes of f The Ibis 9 I 
have erroneously applied the specific name erythropterus to 
Natal and Transvaal examples of this species.—J. H. G.] 
Laniarius atrococcineus (Burch.). Crimson-breasted 
Bush Shrike. 
These birds are tolerably common on the Upper Limpopo, 
amongst the thorny and dense mimosas which bear the name 
of cat-thorns, where it is not always an easy matter to follow 
them or even to get a bird that has been shot.
