(200) Pomatorhinus schisticeps cryptanthus.
Pomatorhinus schisticeps cryptanthus Hartert, Bull. B. O. C, xxxvi, p. 35 (1915) (Margherita, Assam).
Vernacular names. Dao buku-galao (Cachari).
Description. Differs from the last in having the upper parts less olive and more rufescent, the red of the neck and flanks a brighter, lighter chestnut and, according to Hartert, it is a trifle smaller.
Colours of soft parts. As in the last bird; the iris is often a golden yellow.
Measurements. A little smaller than schisticeps; wing 94 to 102 mm.
Distribution. Hills South of the Brahmaputra from the Mikir Hills and Cachar to Margherita.
Nidification similar to that of P. s. schisticeps, breeding from about 2,000 feet upwards to at least 5,000 feet but principally about 4,000 feet. It builds its nest often in bamboo-jungle and also in scrub, edges of cultivation and in forest, especially when there are open glades and streams with grassy banks. The eggs number three or four, very rarely five and sixty eggs average about 26.6 x 19.2 mm. The breeding season lasts from the end of April to late July.
Habits. Those of the last bird; this race, however, is not a noisy bird and, unless alarmed or excited over some special find, one seldom hears more than a secret low, chuckling note and the usual call of " hoot-hoot-hoot." It is, of course, a poor flyer like all the Scimitar-Babblers but I should not call it a skulker as it often feeds practically in the open bamboo-jungles, where it is very easy to watch it. It can hop at a great pace, proceeding in long bounds and when so engaged might easily be mistaken for a frightened rat. Its food is principally insectivorous, but possibly it also eats grain and seeds.
