The bill is curved throughout; there are no hairs overhanging the nostrils but the rictal bristles are well developed. There is only one species in the genus confined to S. India and Ceylon, where it is repre- sented by three races. Rhopocichla atriceps. Keij to Subspecies. A. Crown and sides of the head black . . H. a. atriceps, p. 281. B.

Nidification. The Black-headed Babbler appears to breed in almost every month of the year from December to August and probabl}' in the other three also. It makes an oval nest of grass lined with softer bits of the same which it places in bamboos, grass and I'eeds by roadsides through jungle, in reed-beds or scrub- iungle. It is found during the breeding season from the lower hills up to 6,000 feet. The eggs, two in number, are pure Mdiite with numerous small spots and dots of dark purple-red scattered over the whole surface but generally more numerous at the larger end. The texture is hard and glossy. Twenty eggs average about 19"2xl3'y mm. Hahits. The birds of this genus are said to have much the same habits as those of Pellorneum, i. e. they are shy, leather skulking
