Nidification. Col. H. H. Harington writes (Journal B. N. H. S., xix, p. 121):—" It always seems to build its nest, which is of the usual Bulbul type, within 2 or 3 feet of the ground, generally placing it in a bramble-bush amongst long grass and weeds, and almost invariably lays three eggs, only on one or two occasions 1 have taken two incubated eggs." The eggs are exactly like those of Molpastes h. bengalensis hut do not go through nearly as wide a range of variations. The average of thirty eggs is 21.7 X 16.2 mm. and the extremes are 23.5 x 16.5 mm.; 21.3 x 16.8 mm.; 21.0 X 16.0 and 21.1 x15.8 mm.
Habits. A common and familiar bird throughout its range and found from 2,000 to 6,000 feet, frequenting both lighter jungle, scrub, bamboo-jungle, etc. and the quite open country round villages. It does not apparently actually enter gardens and compounds.
The species finlaysoni extends from Tenasserim to the extreme South of the Malay Peninsula, North to Karenni, Kachin Hills, Siam, Annam, Cochin China. Two races are found within the limits of this work.
