Type of $ T.M. No. 4756 ; same coll, and loc., 6.X.08. Differs from 
the male in not being so brightly suffused with yellowish, and its smaller 
size — length, (?) ; wing, 163 ; tail, 93 ; tars., 24 ; culm., 13 mm. 
There are also in the collection five and two $$ from Boror, Beira, 
and Hector Spruit, which give the following measurements : — 
Wing ... 167-174 mm. Tail ... 94-102 mm.

Pternistes cast aneiv enter, spec. nov. 
Closely allied to P. nudicollis , from which it differs in having the 
breast chestnut coloured in general effect as compared with black, each 
feather having the outer portion chestnut. 
This species has in the past been regarded as representing the 
juvenile plumage of P. nudicollis , but there are in the collection four adult 
<J skins in which the spurs are fully developed, two on each leg, and it 
must therefore be regarded as distinct. The distribution of these two 
species seems to be bounded by the Sundays River Valley, P. nudicollis 
occurring to the south and this new species to the north of that river 
only.

Falco horsbrughi , spec. nov. 
Closely allied to F. rujicollis , but larger, lacking the bars on the 
breast and having the crown streaked. 
Crown in general effect chestnut with dark brown streaks, each 
feather having the base and shaft dark brown and the protruding portion 
chestnut ; forehead and a patch on the ear-coverts yellowish white, the 
former merging into the colour of the crown ; eyebrow and a broad patch 
extending below the eye through the cheeks black, the former, continuing 
backwards to the nape, extends down the hindneck and forms two more 
patches, one through the hinder ear-coverts and the other midway 
between the ear-coverts and hindneck ; collar buffish below and between 
the black marks. Lower hindneck dark brown, merging below into the 
general grey and banded dark brown appearance of the lower back ; 
middle and greater wing-coverts, inner secondaries, scapulars, and back 
grey banded with dark brown ; upper tail-coverts like the back, but paler 
and whiter on the sides ; tail also grey and banded, the last band very 
broad and the tip white. Feathers of the top of head, neck, upper back, 
and wing-coverts all more or less tipped with chestnut. Chin and throat 
white, washed with yellowish, merging into buff on the breast and vinous 
on the sides and flanks ; under tail-coverts buffish white with short shaft - 
marks and faint irregular cross-bands of black ; sides of lower breast and 
flanks banded with brown, the former not so distinct and on a darker 
ground than the latter ; thighs also cross-banded. Upper surface of 
primaries dark brown, tips of all and outer margin of the first dull white, 
inner webs banded with white, the first two inclining to rufous near the 
shafts ; secondaries like the back, but whiter on the inner webs in all but 
the innermost, which are darker than the rest : primary coverts not so 
distinctly banded as the primaries ; bastard wing like the primaries, but 
broadly margined on the outer webs with vinous buff ; lesser wing- 
coverts black, margined with vinous buff. Primaries and secondaries 
paler on the under-surface ; projecting under wing-coverts similar but
