1865.) GENERA AND SPECIES OF CYPSELIDZ. 601 
There are four stuffed examples of this species in the Leyden 
Museum from the Cape, and one from Abyssinia, the latter collected 
by Heuglin at Dembea in May 1862, and labelled C. abyssinicus. 
Under this name it is referred to in ‘ Journ. f. Orn.’ 1862, p. 422. 
Levaillant’s Martinet a croupion blane (Ois. d’Afr. pl. 244. f.1; 
unde Hirundo nigra, Vieill. Enc. p. 528, et H. leucorhoa, Shaw, 
Gen. Zool. x. p. 98; et Cypselus leucorrhous, Stephens, Gen. Zool. 
xiii. pt. 2. p. 81) is, as Sundevall suggests (Krit. Framst. p. 51), in 
all probability C. caffer. Levaillant’s figure wants the white throat, 
&c., and is not recognizable. 
Mr. E. L. Layard, who has kindly sent me a skin of this species 
collected in Damara-land by Mr. Andersson, informs me that it is 
a very abundant species at the Cape, and that he has received it 
from all parts of the colony. “It takes possession of the long- 
necked nests of the Cape Swallow (Hirundo capensis), and lays 
four or five pure-white eggs of a truncated shape. It breeds about 
houses. when in town, and about rocks in the country. Its flight 
precisely resembles that of C’. apus, and the two are generally seen 
together. I can only distinguish them by the white rump of the 
former, seen when going away from me.”

Murino-fuscus, gutture albido fusco striolato : alis et cauda eneo 
tinctis : cauda profundissime furcata: long. tota 7°0, ale 5:4,

Hab. Nubia (Licht.) ; vicinity of Chartoum, very common (4n- 
tinorj) ; ‘‘ Nesting in companies, in the Tompalm (Crucifera the- 
baica), Sept 1850, at Elefahn, on the Blue Nile” (Brehm, 1. c.); 
Western Africa, Gold-coast (Nagtglas); Fernando Po (Fraser) ; 
Gaboon (Du Chaillu) ; Mayotte, Comoro Islands (Pollen) ; Mada- 
gascar (HL. Newton). 
Hirundo ambrosiaca, Gm. (S. N. i. p. 1021), is founded on Bris- 
son’s Hirundo riparia senegalensis (Urn. ii. p. 508), which has 
twelve rectrices, according to that accurate describer, and therefore 
cannot be a Cypseline bird. We must consequently adopt Lichten- 
stein’s name for this species, founded on Nubian specimens. 
The skin from which the characters are taken is from Gaboon 
(Du Chaillu). Two other examples in the British Museum (from 
Fernando Po) are smaller, and have the throat whitish, minutely 
streaked with black. A fourth from the Niger Expedition is nearly 
similar, but has the throat dark, nearly uniform with the body below, 
and scarcely any indications of striations. A Madagascar skin in 
Mr. Newton’s collection measures: “long. tota 6°4, alee 5°3, caudee 
rect. ext. 3°7, med. 1:7.” 
I cannot make out this species without a larger series of speci-
