norus they are pure white. The wing in M. polyzonus measures 12 
inches, in M. canorus, 15 inches. 
16. W. Polyboroides radiatus [ Scop.). {Falco gymnogenys, Temm.) 
17. N. Circuspallidus, Sykes. 
18. W. Scops leu cot is (Temm.). 
19. W. Scotornis climacurus (Vieill.). 
20. Caprimulgus infuscatus, Cretzschm., female. Agrees with 
Riippell’s plate, but wants the white wing- and tail-spots of the male 
bird. 
21. W. Eurystomus afer (Lath.). ( E . orientalis, Rupp.; E. ru- 
bescens, Vieill.; Collarispurpurascens, Wagl.) 
22. W. Coracias abyssinica , Gm. ( Coracias cciudata , 3Vagl.) 
23. W. Coracias ncevia , Laud. (C. levaillanti , Rupp.; C. ww- 
chalis, Swains.) 
24. W. Ceryle rudis (Linn.). ( Ispicla bicincta, Swains.; I. bitor- 
quata , Swains.) Identical with specimens from Smyrna and S. Eu¬ 
rope. The individuals with two pectoral hands (I. bicincta , Swains.) 
are the males. 
25. N. V. Merops albicollis, Vieill. (31. cuvieri, Licht.; 31. sa- 
vignyi, Swains.) 
26. W. Merops milieus, Gm. (31. superbus , Shaw; A/, cceruleo- 
ceplialus, Lath.) 
27- W. Merops lamarcki, Cuv. (M. viridissimus, Sw.; 31. cegyp- 
tius, Kittlitz ; 31. viridis, Rupp.) Closely allied to 31. viridis, Linn., 
of India, but smaller, with a larger mixture of golden yellow r in the 
plumage, the throat not blue as in 31. viridis, and the remiges are 
rufous on both ivebs, with scarcely any tinge of green externally. 
28. W. Merops erythropterus, Gm. (3T. minulus, Cuv.; 31. col¬ 
laris, Vieill.; 31. lafresnayei, Guerin.) 
29. Irrisor senegalensis (Vieill.)? The Kordofan specimens agree, 
in the shortness and nearly straight form of their beak, with the 
black-beaked species of W. Africa, 1. senegalensis, Vieill. ( Nectarinia 
melanorhynchus, Licht.), but in the red colour of this organ they 
agree with the Cape species (1. erythrorhynchus). It is w*ell known 
that the females of the latter have the beak much shorter and straighter 
than the males, yet in these Kordofan specimens the beak, though of 
the same length, is considerably straighter than in the female birds 
from the Cape. Like 1. senegalensis they have a broad white bar 
crossing the inner webs of the first three, and both webs, shaft in¬ 
cluded, of the remaining primaries ; while in 1. erythrorhynchus the 
white bar of the primaries is much narrower, and divided by the black 
shaft. 
30. Nectarinia metallica, Elirenb. 
31. 3V. Nectarinia pulchella (Linn.). 
32. Phylloscopus trochilus (Linn.). Identical with British spe¬ 
cimens. 
33. Saxicola deserti, Temm. 
34. Saxicola oenanthe (Linn.). 
35. Saxicola isabellina, Cretzschm. This is probably the Sylvia
