LIST OF A COLLECTION OF BIRDS FROM 
11. Hirundo rustics Linn. Identical with British specimens. 
12. Platystira pririt (Vieill.) ; Levaill. Ois. Af. pi. 161. 
13. Platystira albicauda , Strickland. Size, large. Front pure 
white, extending laterally as far as the eyes ; crown, lores, and 
cheeks, deep glossy black; a white spot oil the nape surrounded 
by black ; back slaty grey ; scapulars black externally, slaty grey 
within, and obscurely tipped with white ; wings black, the margins 
varied with white ; the middle and greater covers next the body 
pure white; basal third of primaries and the extreme tips of the 
three first, white ; secondaries and tertials black, tipped with white, 
the four inner secondaries next the tertials, white for one-fourth 
from the base ; rump and upper tail-covers thick and downy, cine- 
reous like the back, each feather with an elongate subterminal tear- 
like white spot, the extreme tips blackish ; tail wholly pure white 
except an elongate tear-like spot of black on the medial pair, nearly 
bisected longitudinally by the white shaft. Chin, throat, and sides 
of neck, pure white, below which is a black pectoral collar ; sides 
of breast cinereous ; lower wing-covers black ; middle of breast, 
abdomen, and lower tail-covers, pure white ; feathers of the tibise 
white at the tips, black at the base ; beak and legs black. 
Total length, 5.3 ; beak to front, 6j, to gape, 9, wide, 2j, high, 2 ; 
wing, 3.5; medial rectrices, i .8, external, i.7; tarsus, i.2. 
This is the largest species of Platystira that I have seen. The 
beak is stronger and more compressed at the sides than in the other 
species, the tail shorter in proportion, and the first primary longer, 
being nearly two-thirds the length of the fourth. 
14. Dicrurus divaricatus, Licht. Agrees with specimens from 
Kordofan. 
15. Lanius subcoronatus, Smith ; Zool. S. Af. pi. 68. 
16. Lanius collaris, Linn. ; Levaill. Ois. Af. pi. 62. 
17. Lanius minor, Gm. Differs from specimens from South 
Europe only in the base of the lower mandible being whitish, and 
in the rather smaller extent of black on the third pair of latera 
rectrices.
