Bill of Dryoscopus cubla. Bill considerably bent, hooked and notched; the proportion of height to breadth varying much even iu one and the same species, e.g. iu D. cuhJa, leading thus to the broad-billed D. sabinei, for which the generic term Chaunonotus was invented. Nostrils oval, in front of a coriaceous groove, which is overgrown with little feathers ; nostrils themselves exposed ; bristles weakly developed. Pirst jirimary be- tween half and three quarters of the length of the next primarj'. Wings rounded, fourth and seventh primaries forming the tip. Tail rounded, equal to or slightly shorter than wings. Tarsus covered * Among the doubtful species belonging to this obscure and diiScult genus may be mentioned the following :— Devoscopus somalicus. Lanius somalicus, Hartl. Ibis, 1859, p. 342; Finsch ^~ Hartl. Vdg. Ostafr. p. 3.33 (1870); Heuglin. Faun. roth. Meer. no. 125. Dryoscopus somalicus, Hcvyl. Orn. N.O.-Afr. pp. 460, csvii.
