OTOCOMPSA.

Distribution. South Chin Hills and South Kachin Hills to Tenasserim, Arrakan and the whole of the Central Hills of Burma, Siam and Shan States. Andamans and Nicobars.

This form is another of the interesting cases in which birds from the two extremities of a range are nearer than they are to those in the centre. In India we have a horseshoe of which Assam and the Chin Hills may be said to form the centre, whilst Ceylon and the Malay Peninsula form the two extremities. Evolution has evidently gone on on similar lines with very similar results in the two latter places, though we need not infer from this that these extremities were ever linked together.

Nidification. Though there is little on record in regard to this form, its nests and eggs, habits of breeding, etc. seem to differ in no way from those of the Indian birds. In the South it lays two or three eggs, in the North three and more rarely four. A large series sent me by one of my collectors from Pegu are exactly like a series from Madras and measure on an average for forty eggs 20.0 × 15.9 mm.

The breeding season seems to be February to April but doubtless extends over a much longer period than this.

Habits. Takes the place in Burmese gardens, villages and towns of O. e. emeria in Northern India etc. and of the Madras bird in Southern India. It is not found in forest or any kind of heavy jungle.
