with grass and feathers. The eggs are pure white. They breed 

 from December till March. Buchanan Hamilton says they ai'e 

 migratoiy about Calcutta, coming in October and leaving in 

 ^iarch. I have seen them frequently in IMay, and during the rains 

 also, but they were more scattered at this time. It is possible, 

 however, that some may migrate northwards to China, and 

 northern Asia, and perhaps have a second summer brood there. 

 It is abundant in Burmah on the Irrawaddy river, and it is 

 found throughout the Indo-Burmese countries generally, extending 

 to China. 



2nd. — Crao- Martins. 



These differ from the Sand Martins in the habit of making 

 their nests on rocks, and indeed belong to a different type alto- 

 gether, distinguished, among other points, by the white spots on

 but I procured it at Vellore, and Scringapatam, in both places 

 breeding on the large fort walls; also on rocky hills throughout the 

 Camatic and laUe land, andin Central India. It also extends to the 

 N. W. Pro\incep, having been obtained at Delhi by Major Tytler, 

 and I saw it at Allahabad breeding on the fort wall there. 1 have also 

 found its nest on a rock over-hanging the road on the Goodaloor 

 Ghat of the Keili:herrics, at about 4,000 feet of elevation. It also 

 builds occasionally in the eaves of lofty houses, and other large 

 buildings in the Deccan, as I saw at Jaulna. The nest is small,
