(835) Graminicola bengalensis striata.
The Siam Large Grass-Warbler.
Graminicola striata Styan, Bull. B.O C , i, p. 6 (1892) (Hainan).
Vernacular names. Nok-hang-nak (Siam).
Description. Differs from G. b. bengalensis in having the black streaks above much less wide, so that the general impression given is of a much more rufous bird. The white markings on the hind neck are less conspicuous.
Colours of soft parts as in the preceding race.
Measurements. Wing 59 to 64 mm.; tail 71 to 80 mm.; tarsus 24 mm.; culmen 13 to 15 mm.
Distribution. Hainan, Siam, Tenasserim. It will certainly be also found in some of the intervening countries in suitable localities.
Nidification. Mr. B. G. Herbert found this Grass-Warbler breeding in some numbers round about Samkok in Siam, and my collector, Partridge, also found it in Eastern Tenasserim. The nest is a very deep cup, possibly more or less domed, built of coarse grasses and lined with finer. It is placed either in clumps of grass or in low bushes. The full clutch of eggs appears to be three or four. The ground-colour varies from pure white (unusual) to pale cream and the markings consist of fine specks, sometimes small blotches, of light reddish brown or of purplish brown, scattered freely over the whole surface but generally denser at the larger end, where they form indefinite rings or caps. Thirteen eggs average 19.0 x 15.0 mm.: maxima 20.8 X 15.3 and 20.3 x 16.0 mm.; minima 18.0 x 14.8 and 18.3 x 14.1 mm.
They breed from late June to early August.
Habits. These do not appear to differ from those of the last bird.
