I have no doubt, when Mr. Rainbird has time to pay more 
attention to the less gaudy birds, many more of our New South 
Wales species will be found in Queensland. 
XXIX.— The Ornithology of India. — A Commentary on Dr. 
Jerdon’s c Birds of India. 3 By Edward Blyth, late

The average of adult Swallows from the Indian region and 
China are smaller than the average of European examples, to 
the extent sometimes of an inch in length of wing; but some 
Indian are undistinguishable from European specimens. Thus 
Dr. Jerdon remarks, “ On carefully comparing specimens from 
England and Algiers in the Museum at Calcutta with Indian 
specimens from various parts of the country, I can detect no 
difference.” Mr. Gould has lately described a H. fretensis 
(Handb. B. Austral, i. p. 110) from North Australia and Java; 
and this seems to be the same Swallow that Dr. Jerdon indicates 
as exemplified by one specimen from Java and another from 
Southern India (p. 157), in which case H. frenata has to be 
added to the ‘ Fauna Indica.’ The H. tytleri , Jerdon (Appen¬ 
dix, p. 870), comes very near to H. cahirica of Palestine and 
Egypt, but is rather smaller and has much less of the black 
gorget. It may be said to hold that relationship to H. guttu¬ 
ralis which II. cahirica does to H. rustica ; and H. hyperythra of 
Ceylon is an analogous rufous-bellied race of H. erythropygia. 
83. Hirundo domicola. 
Mr. Mottley obtained it in Borneo (P. Z. S. 1863, p. 217).
