superciliosus-like specimens from Kaftraria, I may mention that the female 
of C. g. caeruleiceps is larger than the male, and is more or less profusely 
banded <^the whole of the upper surface from the forehead to the upper 
cail-coverts, the wings, and the tail, and rather less on the under surface, 
with only a patch on the throat and another down the middle of the breast 
not banded ; there is no black in the plumage except for these bands ; 
and the collector has noted the following points : “ Iris, darkish hazel ; 
legs, slate black ; lower mandible, pale flesh ; upper mandible has lower 
portion pale flesh and upper portion tip flesh, deepening to dark brownish 
black at posterior portion ; stomach, grasshoppers, beetles, and catterpillar.

The series of skins of C. burchelli in the Transvaal Museum collection 
contains the following, including some very young specimens : — 
10 Knysna (Marais and Rex). 
5 Grahams town. 
5 Red Hill, coast Nataly (Arnold). 
1 Pietermaritzburg (Natal Museum). 
1 Barberton (Drever). 
4 Hector Spruit (Streeter). 
3 Beira (Sheppard).

2 Woodbush (Noome). 
1 Rustenburg (Noome). 
1 Warmbaths (Noome).

1 Pienaars River, Pretoria District (N. Roberts). 
1 Modderfontein, Transvaal (Haagner).

A study of this series clearly shows the transitions of markings from 
the very young to fully adult stages. The juvenile specimens show the 
following characters : Wing quills much banded ; top of head brown ; 
hind neck to scapulars with numerous white streaks ; sides of throat, crop, 
and breast with feathers having a serrated line down each side ; and a 
distinct yellowish eyebrow. As the birds become older these characters 
gradually disappear, until in fully adult ones the wing quills are uniform ; 
the top of the head bluish black, this colour extending over the hind neck 
and losing the pale shaft lines, though some light coloured shafts sometimes 
remain on the lower part either on or beyond the limits of the bluish black 
colour ; sides of throat, crop, and breast without the serrated lines on the 
feathers ; and the eyebrow not white. It is to be noted, however, that 
adults frequently still show traces of these juvenile characters, either one 
or other of them still sometimes remaining after all the other juvenile 
characters have disappeared ; but it seldom happens that this remnant of 
juvenility is very pronounced after the head has become bluish black and 
the wing quills have become uniform. Precisely the same characters 
appear in the different stages of superciliosus, and it is on these grounds 
that I am doubtful as to the distinctness of C. flecki, which is found in
