Length about 20; tail 7.5; wing 9.5 ; tarsus 1.25; bill from gape 1.5.
Distribution. Himalayas of Nepal, Sikhim, and Bhutan, at moderate elevations (about 2000-6000 feet); also Assam and the Hills south of the valley *.
Habits, &c. Very similar to those of Carpophaga aenea, the note of this Pigeon being even deeper. It is said to lay a single egg from May to July. An egg measures 1.72 by 1.28.
* The bird from North Cachar described as C. insignis by Lieut. Beavan in Godwin-Austen's paper (J. A. S. B. xxxix, pt. 2, p. 111), I think, must have been G. aenea. It was only 165 inches long, had a slate-coloured head and dark red irides, and no mention is made of a pale terminal band on the tail.
