(127) Dryonastes galbanus. 
Auvstren’s LauGuine-THRUSH. 
Garrulax galbanus Godw.-Aust., P.Z.8., 1874, p. 44 (Manipur). 
Dryonastes galbanus, Blanf. & Oates, i, p. 68. 
Vernacular names. None recorded. 
Description. A narrow ashy-white supercilium ; crown and nape 
ashy-brown; rest of head and chin black; upper plumage, wing- 
coverts and outer webs of secondaries ochraceous brown; the 
outer webs of primaries ashy-olive; inner webs of all quills 
brown ; tail greenish-ashy, the four middle feathers broadly tipped 
with black and sub-tipped whitish, the others broadly tipped with 
white preceded by blackish; lower plumage yellow washed with 
olive on the sides ; under tail-coverts white. 
Colours of soft parts. Bill black; legs ash-grey; -iris red. 
brown (Godw.-Austen). 
Measurements. Length about 240 to 250 mm.; wing 92 to 96 
mm.; tail about 105 to 110 mm.; tarsus about 35 mm.; culmen 
about 20 to 22 mm. 
Distribution. Manipur and Chin Hills. 
Nidification. In all respects like that of the last bird. Thirty 
eggs average 24°3 x 18°5 mm. and cannot be distinguished from 
those of that Laughing-Thrush, except that they area trifle smaller 
and perhaps rather less glossy. 
Habits. Similar to those of ruficollis, but found principally 
between 2,500 and 5,000 feet. It is said also to be more of a 
forest bird in the Chin Hills and less restricted to serub and 
bush-jungle, though Hume found it frequenting grass-lands in 
very large flocks, 50 to 80 in number, in Manipur. 
Genus GARRULAX Lesson, 1831. 
The genus Garrulax differs from Dryonastes in having fewer 
bristles and hairs covering the nostrils, which are clearly visible. 
The feathers of the head are in most species long and ample, and 
in some are developed into long crests. 
At first sight the White-headed Laughing-Thrushes appear to 
be divided trom the rest of the genus by their fine crests and by the 
fact that they lay eggs of a totally different character to those of tlie 
other genera. Now, however, that Mr. J. Stewart has taken many 
nests of G. delesserti in Travancore, it is found that this bird, 
though in other respects like the species which lay blue eggs, lays 
round white eggs, exact miniatures of those of G. leucolophus. 
All the species within Indian Jimits lay unspotted eggs, either 
blue or white.
