Sub- family Carpliopagince, 

 (414) Caepophaga ^nea.— The green Imperial Pigeon. 

 Hume, No. 780. 



This bird may be frequently met with nearly all over North Cachar, 

 but nowhere have I met with it in such large flocks as those in which 

 the next bird often collects. It is of course equally plentiful in the 

 plains, where it breeds, as it is higher in the hills, and I have seen it on 

 the very highest of these, though it is most numerous in well wooded 

 valleys at about 2,000 feet elevation. 



The size of the plmns and berries which these birds swallow is most 

 astonishing. I have taken jamans from their crops, some of which I 

 am sure were almost as big as their own heads. 



My eggs average 1*90" X 1*40", but they vary considerably in size, 

 the smallest being only 1-69" X 1*29" and the biggest 2-03" X 1'48", 

 nearly all are over 1*85" X 1*35". 



The eggs mentioned in Hume's " Nests and Eggs" (vol. II, p. 367) 

 seem to run much smaller, some being stated to be only 1*6" X 1'25". 



(415) Caepophaga insignis. — The Ruddy-backed Imperial Pigeon. 



Hume, No. 781. 



Extremely common in certain localities, but at the same time is not 

 so widely spread as C, cenea. 



I have taken its nest on several occasions, and do not find that there 

 is any visible difference between that of this bird and that of the species 

 just mentioned. It normally lays but one Qgg., but I have taken two 

 from the same nest. The average of the eight eggs I have seen of 

 this bird is only 1'8£'' X 1*32", decidedly smaller than those of C. cema, 

 although the bird itself is rather the larger of the two. 



(416) Carpophaga griseicapilla, — The Grey-headed Imperial 



Pigeon. 

 Hume, No, 781 Ter. 

 Hume did not find this bird rare in parts of Manipur, but here, in 

 the country adjoining Manipur, I have seen but one typical bird, and 

 this one was a male caught by a Naga on its nest which contained the 

 usual single egg. It measu-res l'93"Xl*44". 



The ruddy-backed bird of these hills approaches C. griseicapilla 

 in ihat it has the ear-coverts, cheeks, forehead and anterior crown 

 quite as grey as they are in that bird, but the posterior crown and
