1865. ] GENERA AND SPECIES OF CYPSELID&. 599 
Palestine (Tristram); Afghanistan (Blyth); Cashmere (ddams) ; 
Egypt and Nubia (Riipp.); Coasts of Black Sea, nesting in cliffs 
(Demidof’) ; Eastern Siberia (Radde); Madeira (Harcourt); Ben- 
guela (Monteiro) ; Cape Colony (Layard) ; Natal (Ayres). 
There are two South-African specimens of a Swift in the Leyden 
Museum labelled ‘* Cypselus barbatus,” which differ from European 
examples principally in their lighter colour above, particularly on the 
secondaries and scapulars, in the white feathers of the gular patch 
presenting a narrow black central line, and in the feathers of the 
lower back, belly, and under wing-coverts being narrowly margined 
with white. Two examples from Natal, collected by Mr. Ayres* 
are similar. It is possible that this form may be entitled to rank as 
a species, to which Temminck’s MS. name may be applied. But it 
would be desirable to obtain more skins for comparison, particularly 
examples from other parts of South Africa. 
Mr. Layard says C. apus arrives at the Cape early in November 
(Cf. Ibis, 1864, p. 134), but does not breed in the colony, as far as 
he can ascertain. 
Specimens collected by Heuglin at Keren, on the White Nile, in 
the Bremen Museum (probably those referred to in his article 
Journal f. Ornithologie, 1862, p. 422), are stated by Mr. Finsch to 
belong certainly to C. apus, although two of them present slight 
white marginations on the under surface. Heuglin’s C. aterrimus 
(/. c.) is probably not different.

2. Paulo minor. 
Hab. Eastern Siberia, Baikalia (Pallas § Radde); China, summer 
visitant from Amoy to Talien Bay (Swinhoe) ; Formosa (Swinhoe) ; 
Pinang (Cantor); Malay peninsula (Blyth); Eastern Australia 
(Gould) ; Cape York (MacGillivray). 
I cannot distinguish Australian and Asiatic examples of this spe- 
cies. It would be desirable to know whether it occurs in the great 
Indian islands and the Moluccas. There are no specimens from.these 
localities in the Leyden Museum, nor did Mr. Wallace obtain it. 
Mr. Swinhoe says of the species (/. ¢.) :—“ Sexes of similar plu- 
mage ; wings and tail of variable length in both, in the former seldom 
more than 3 inch difference between two specimens.”
