(178) Grammatoptila striata austeni.
AUSTEN'S STRIATED LAUGHING-THRUSH. .
Grammatoptila austeni Oates, Avifauna B. I., i, p. 104 (1889) (Dafla Hills).
Vernacular names. Daopa (Cachari).
Description. Differs from the preceding bird in having two broad dark coronal bands meeting on the nape; no shaft-stripes on the crown, and those elsewhere narrower but better defined.
Colours of soft parts. Iris red-brown to dark red; legs and feet pale slaty-grey, soles yellowish; bill dark slaty-brown or " bluish-horny " (Stevens).
Measurements as in G. striata striata.
Distribution. Hills south of the Brahmaputra as far east as Margherita. Stevens procured this form on the eastern watershed of the Sabansiri River, and Falkiner and Kemp both procured it on the Mishmi Expedition, so that it appears to work round the head-waters of the Brahmaputra, Dibong and Dihong as far west as this river.
Nidification. I found this bird breeding freely above 4,500 feet in the Khasia Hills and more rarely so in the N. Cachar Hills. Nest and eggs like those of the last bird, but I have never seen any egg marked at all. Twenty eggs average about 31.5 x 23.5 mm.
Habits. Frequents pine-woods as well as other forest, provided there is any undergrowth; otherwise its habits are like those of G. s. striata.
