ASSAM, SYLHET AND CACHAR. 27: 



it abounds in Dacca, for two and three successively not a bird 

 is to be seen. I say this on Mr. F. B. Simson's authority, who 

 was for many years Commissioner of Dacca, to whom I owe 

 all my specimens from that locality and who for years specially 

 watched this species, to which he first drew Dr. Jerdon's 

 attention. 



I have this species from N.-E. Cachar and also from Sadiya, 

 but know nothing further of its occurrence in Assam, Sylhet 

 or Cachar. 



[I procured several specimens of this species, which I know 

 well, having seen numbers in Dacca during my sojourn in the 

 Dibrugarh district. They are only observed during the cold 

 weather and at long and irregular intervals. — J. E-. C] 



As to B. Burmah — in Tenasserim we only met with 

 it about Tavoy— Mr. Gates says it is very common in 

 Eastern Lower Pegu. It occurs in Northern Pegu and in 

 Arakan, but its distribution is still undefined. 



856is.— Hirundo nipalensis, Hodgs. 



Though not common, I met with this occasionally both in the 

 hills and plains of Manipur. 



Two males measured : — Length, S'O, 80 ; expanse, 12-6, 125; 

 tail, 4-4, 4-4 ; fork of do., 2-3, 2'45 ; wing, 4-7, 4 65 ; tarsus, 

 0-4, 0-5 ; bill from gape, 057, 055 ; weight, 0'65, 0-66oz. 

 Legs and feet dull purplish brown ; bill black ; irides brown. 



I found this species common about Karimganj in Sylhef, 

 and have received it from N.-E. Cachar, but (though it 

 doubtless occurs) from no place in the valley of Assam. 



Godwin-Austen gives H. erythropygia from the Dafla 

 hills, but I have little doubt that his birds really belonged 

 to this species, which also occurs, it may be noted, in every 

 province of B. Burmah. 



SSg'wa^.— Hirundo substriolata, Eume (S. F., V, 264). 



I met with this specie^, I believe, repeatedly in the valley 

 of Manipur ; it was always in flocks, hawking high in air. Gn 

 only two occasions did I get single long shots, each of which 

 secured a specimen. Gne a young male measured : — Length, 

 8-4 ; expanse, 131 ; tail, 44 ; wing, 4*9 ; tarsus, 057 ; 

 bill from gape, 6; weight, O'Soz. This specimen has a 

 trace of a white spot on the inner web, near the base of the 

 outer tail feathers. 



I have this species not only from N.-E. Cachar, but also from 

 near Dibrugarh, where, writes Cripps, "it is fairly common 

 during the cold season." Possibly it occurs in Pegu {vide 

 S. F., Ill, 42) and in Karenee {vide S. F., VI, 44;.
