84. HiRUNDO FiLiFERA must staiid, it a])pears,as H, ruficeps, 

 Lichtenstein; but as the African race is stated by Gould to diflfer 

 in some points from the Indian one, the former name may per- 

 haps still hold good. It is figured by Gould, B. of Asia, pt. xviii. 



85. HiRUNDO DAURICA. 



Two races are now allowed by all ornithologists to occur in 

 India. One, 85, is true Hirundo or Cecropis daiirica, figured 

 by Gould, B. of Asia, pt. xx. pi. 9 ; the other will stand as 



85 bis. Cecropis erythropygia, Sykes. 



It is this race which commonly breeds in Southern India, 

 whilst in the Himalayas H. daurica is stated to be the species that 

 breeds ; but of this I am by no means fully satisfied. A third 

 race has been suspected by some ornithologists, which some 

 consider to be H. rufula. 



85 te7\ Cecropis hyperythra, figured by Gould, B. of 

 Asia, pt. XX. pi. 11, may be said to be a localized rufous race of 

 this group. It appears, however, to extend also to Malacca, as 

 a specimen in Lord Walden's collection from that locality ap- 

 pears to be the same bird. 



86. HiRUNDO fluvicola. 

 Hirundo empusa, Gould. 



This Swallow has been assigned by Gould to a distinct genus, 

 Lagenoplastes, and is figured by him in B. of Asia, pt. xx. pi. 14. 

 The bird formerly named by him empusa is the bird mentioned in 

 ' The Birds of India,' on Adams's authoi-ity, as occurring in the 

 Punjab ; but it turns out to be the same bird, as the white spots 

 on the lateral tail-feathers are, it appears, chiefly found on old 

 males, the females and young birds being without these spots. 

 Mr. Blanford has recently found it in the same localities as the 

 first procured by myself. He also observed apparently some of 

 the very colonies of nests I had noted, and fortunately procured 

 the eggs. He notices that they " invariably " build beneath an 

 overhanging rock or bank over deep water, returning to the 

 same spot every year. I observed oue colony of nests near 

 Nagpore, however, where the nests, which were in a sort of cavern, 

 were easily reached by the hand from the shallow water at the
