Maunbhoom, which I unhesitatingly put down as H. rustica; for they have the band across the chest 
clearly developed, though not so broad as in European birds, and in two it is slightly interrupted by 
reddish feathers. Two specimens from Darjeeling are labelled H. tyéleri; but these I should not 
separate from our bird, as the pectoral band is fully developed; and though the underparts are very 
rufescent, still they are not more so than is often observable in our bird in spring, and [I can match 
Lord Walden’s bird to a shade with some of my European ones. His Lordship informs me that he 
possesses much redder examples, which he cannot at the moment find; and this I can well believe, as I 
possess one from the Khasi Hills, obtained by the late Dr. Jerdon, which closely resembles examples 
from Lake Baikal and North America in having the band on the breast interrupted in the middle; and 
the underparts are very rufous, nearly as much so as pale examples of Hirundo savignii. 
A single specimen from Ceylon, in winter plumage, does not in the least differ from our bird, and is 
remarkable for having the underparts below the breast-band very white. 
There is also a single bird from Assam which is remarkable in having the red on the throat very much 
developed, extending over the portion where the dark band usually passes in the middle of the chest, 
the band being merely indicated on the sides of the chest; and the rest of the underparts are white. It 
resembles H. horreorum, except that the underparts are much whiter, and it is a smaller bird, being 
scarcely larger than H. javanica; but it has the underparts whiter than in that species, and the tail is 
much more deeply forked. 
From the Andaman Islands there are three specimens, all of which are referable to Hirundo rustica, and 
differ imperceptibly from European examples. 
Three birds from Java are also identical with European specimens, except that one has the red on the throat 
much extended, and the band across the breast comparatively narrow. Specimens from Celebes also 
resemble this last-named bird in having the band across the breast narrow, and the rufous on the throat 
extended over a larger area than in the average of European birds, from which they do not otherwise 
differ. An example from Morty Island, in not quite mature plumage, resembles these, but appears as 
if, in mature dress, it would have the breast-band broader. 
From Malacca there are in the series lent to me by Lord Walden three specimens of Hirundo rustica which, 
though they appear a trifle less in size, are otherwise similar to European birds; but besides these there 
are two other examples from Malacca, and two collected by Dr. A. B. Meyer in the Togian Islands, 
which are certainly distinct from Hirundo rustica, and are, I consider, true Hirundo javanica. These 
birds are smaller than Hirundo rustica, have no band across the breast, the throat and upper breast 
being rusty red with an orange tinge, the sides of the breast dark sooty grey, and the underparts dull 
white, with slight striations, which are scarcely distinguishable in some specimens ; under tail-coverts 
sooty grey, tipped with white; the upper parts are as in H. rustica, but the red frontal patch is very 
large. They measure—culmen 0:4, wing 0:4, tail 2:1, tarsus 0°37. None of these specimens have the 
lateral rectrices much elongated as in H. rustica. 
In the Strickland Collection at Cambridge is a specimen from the Philippines, from which islands H. guttu- 
ralis was described. This bird, which I have carefully examined and compared, is certainly nothing 
but Hirundo rustica in the plumage of the first winter, similar to that above described from the Cape 
of Good Hope. 
I possess two specimens from Lake Baikal, one of which is precisely similar to examples from Duetias, in 
Central America, in Mr. Salvin’s collection, and one from Alaska in the same collection, whereas the 
other has the band across the breast nearly meeting, instead of being interrupted by red; and both 
have the underparts very rufous, almost more so than the average of American specimens, but not 
nearly so dark as in Hirundo savignii. These specimens very closely resemble one from the Khasi 
hills, determined by Dr. Jerdon as H. tytleri. 
In Lord Walden’s collection are two specimens from China and one from Japan, which have the band across
