84. Hirundo ruficeps, Licht.; Gould, B. As. part xviii. pi. 
Abyssinia (Riippell), and Khartum (Antinori). Mr. Gould, 
however, doubts the identity of the Indian and African birds, 
remarking that “fine examples of both now before me appear to 
differ too much to admit of their being considered examples of 
one and the same species. The Gambian specimens are much 
smaller, have a less amount of rufous colouring on the head, and 
shorter tails." 
85. Hirundo erythropygia, Sykes. 
This is considerably smaller than H. daurica , Pallas, of China; 
the wings are respectively 5 in. and 4*25 in. to 4*75 in. in length. 
Both races, however, may prove to occur in India. Dr. Bree 
erroneously identifies H. rufula , Temrn., with H. daurica . The 
true H. rufula (which Mr. Tristram observed to be so abundant 
in Palestine) is figured by MM. Jaubert and Barthelemy- 
Lapommeraye (Rich. Orn. du Midi de la France, p. 308). Mr. 
Gould's figure in the f Birds of Europe' of his supposed H. 
rufula represents, as is well known, H. senegalensis. In the 
British Museum I saw a specimen of true rufula from Afghani¬ 
stan. According to Mr. Swinhoe, H. daurica is “ represented 
in Japan and Formosa by larger varieties." H. alpestris japonica 
is figured in the f Fauna Japonica' (Aves, tab. xi.). Comparing 
a specimen of H. striolata, T. and Schl. [nee Riippell), from the 
island of Flores, which Mr. Wallace kindly lent me for the 
purpose, with the figure cited, I could perceive no difference 
whatever. On the label of that specimen was written—“ This 
species was seen in East Java, flying along the roads." 
86. Hirundo fluvicola. 
The Swallow referred to, as described by Dr. A. Leith Adams 
(P. Z. S. 1859, p. 176), is distinct. Mr. Gould possesses a 
specimen, and designates it Lagenoplastes empusa . It certainly 
accords nearly with the description of H. fluvicola; but there is 
no white on the tail-feathers, and the crown can scarcely be 
called “ dark rufous." It closely resembles the Australian L. 
ariel, Gould (Handb. B. Austral, i. p. 113) ; but differs in the 
rump being brown instead of white, and in the striation of the 
fore-neck and breast being much more developed, the black
