520 DR. O. FINSCH ON BIRDS FROM NORTH-EASTERN 
Hirvnpvo rustica, L., p. 347. no. 99; Finsch & Hartl. Vogel Ostafr. p. 134. no. 55. 
“Common eyerywhere. ‘This bird abounded on the shores of Annesley Bay in the 
middle of June.” (Blanf.) 
Von Heuglin also states this species to be resident along the Red Sea. 
Hirunpo Fiuirera, Steph.; Finsch & Hartl. Vogel Ostafr. p. 141. no. 58. H. ruficeps, 
Licht., Blanf. p. 348. no. 101. 
Mr. Blanford obtained a single pair near Aguala, halfway between Adigrat and 
Antalo, and remarks, “The outer tail-feathers are very much shorter than is usual in 
Indian specimens, and I am far from convinced that the species are identical.” The 
length of the outer tail-feathers is noticed as 4°6; this is only a little smaller than in 
Indian specimens. 
CHELIDON uRBICA (L.), p. 349. no. 103. 
“ A single specimen obtained at Koomaylee in February.” 
CotyLe cincta (Bodd.), p. 349. no. 104; Finsch & Hartl. Vogel Ostafr. p. 144. no. 59. 
“On the shores of the Lake Ashangi in April, and about a fortnight later on the 
banks of a stream near Antalo.” 
CoTYLE RUPESTRIS, Scop., p. 300. no. 105. 
‘¢ A very common bird in the rocky passes, and found almost from the sea-level to 
8000 feet.” It is singular that Von Heuglin notices only (. obsoleta, Cab., from neigh- 
bouring localities in Abyssinia; and one would be inclined to believe Mr. Blanford had 
confounded the species, did he not say “a specimen from Senafé differs in no respect 
from others brought from Southern Europe.” 
The type specimens of C. obsoleta which I saw in the Museum Heineanum, I found 
difficult to distinguish from C. rupestris. 
CotyLe minor, Cab., p. 350. no. 106; Finsch & Hartl. Vogel Ostafr. p. 147. no. 61. 
‘Seen in countless swarms on Lake Ashangi in April.” 
The three allied species C. riparia, C. minor, and C. paludicola, Vieill., are treated of 
in our work on the birds of East Africa, where we state that they occur nearly over the 
whole of Africa. Mr. Tristram (Ibis, 1869, p. 436) expresses his opinion that under 
the name of C. palustris have been confounded two species—one from the north, the 
other from the south. The northern bird, which Mr. Tristram obtained by the Dead 
Sea, and received from Egypt and Abyssinia, being larger than the southern bird, and 
having a large white spot on the inner web of each of the rectrices, except the outer 
and middle covering pair, is undoubtedly referable either to C. obsoleta, Cab., or
