Nidification. Nests and eggs tal^en by Mackenzie in the Chin Hills, not far from the Manipur border, are just like those of the Sikkim Tree-Creeper but the foriuer were placed in small holes in trees. Mackenzie describes them as little pads of moss lined with a few feathers and a little " fluff." An egg sent me, one of a clutch of four, measures 16-5 x 12-9 mm. but others in Mr. Mac- kenzie's own collection are longer, measuring 17-2 to 17-5 mm. This clutch was taken, hard set, on the 7th of May, but young birds were seen on the wing and shot on this date. Two other eggs taken by Mr. F. Grait measure 16-5 x 12-4 and 15-9 X 13 mm.
Habits. Quite similar to that of the Sikkim Tree-Creeper.
