nullah. It lives largely, I think, on insects, and perhaps on any tiny 

 reptile which may cross its path. It ascends high up the mountainSj 

 for, more than once, have I seen it flash across my path close to 

 Guilang, and though they were but flashes there is no other bird which 

 could possibly be mistaken for it. 



I have been told of its having bred at over 4,000 feet, but cannot 

 personally vouch for the truth of this statement.

Sub -Family Cypselinm. 



There are so many gaps in this family as shown merely by their 



nidiflcation in Hmne's ^' Nests and Eggs " that I think it is better to- 



use the classification of these birJs as given in Vol. XVI of the 



Catalogue of the Birds of the British Museum. 



(449) MiCROPUS PACiFicus. — The White-rumped Barred Swift. 



Hume, No. 101 Bis ; Cat.^ B. Museum, Vol, XVI, ^y. 449. 

 I have seen on two or three occasions large flocks of this fine- 

 Swift, but have not had them fly close enough to allow me to obtain 

 any specimens. Hume (" Stray Feathers," Vol. XI, p. 31) records 

 having seen them in Manipur, though he also failed to shoot any, and 

 there is a specimen from Cachar in the Hume Collection in the British 

 Museum. 



(450) MiCROPUS AFFINIS.— The Common Swift. 

 Hume, No. 100 ; Cat., B. Museum, Vol. XVI, p. 452. 

 A bird I obtained in the extreme north of the district may be 

 assigned to this species, but is very dark and has a rather longer tail 

 than usual. 



(451) MiCROPUS SUBFURCATUS. — The Eastern Swift. 

 Ilime No. 100 Bis ; Cat., B. Museum^ Vol. XVI, p. 456. 

 This is the common form of Swift everywhere in Cachar except 

 perhaps in the north, where the district meets the valley of the 

 Brahmaputra. Hartert (Novitates Zoologicce^ Vol. I, No. 4, p. 674) 

 gives a description of a nest and eggs sent to him from K aching, 

 Sarawak. This, like those which I have myself seen, resembled the 

 nest of M. affinis too closely to require any further description from 

 me, though I may note that they were all attached to buildings 

 exactly in the same manner as are those of that bird. I have not been
