Certhia manipurensis Hume, S. F., x, p. 1*51 (1881) (Manipur): Blanf. & Oates, i, p. 331.
Vernacular names. Voh-ti-ti-ling (Manipuri).
Description. Differs from the preceding bird in having the upper parts darker and the throat more fulvous.
Colours of soft parts as in C. d. discolor.
Measurements. Wing 66 to 71 mm.; tail 65 to 68 mm.; tarsus 17 to 18 mm.; culmen 15 to 16.5 mm.
Distribution. Manipur and the Chin Hills South and East of that State. The bird to the East of the Irrawaddy is not known and may be either the Manipur bird or some other "form.
Nidification. Nests and eggs taken by Mackenzie in the Chin Hills, not far from the Manipur border, are just like those of the Sikkim Tree-Creeper but the former 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. Mackenzie'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. Grant measure 16.5 x 12.4 and 15.9 x 13 mm.
Habits. Quite similar to that of the Sikkim Tree-Creeper.
