Iris brown ; bill and tarsus brownish black. Length 23*5-24*1 centims. ; wing 9*2-9*4 centims. This species seems to be the representative of L. bentet in N.E. Borneo, Sulu, and the Philippines. It is characterized by the sharp line of demarcation between the black of the head and the grey of the scapular region. Above, the upper tail-coverts only are ferruginoue. Scapulars dull grey, shading into white below. Under surface creamy white; abdomen and flanks ferruginous. Feathers of tail tipped with white, which becomes more or less eroded with age, the base dirty white or fawn colour, excepting in the two middle pairs, which are of a uniform brownish black. This Shrike was common on Sulu Island, specially affecting small bare isolated trees in the open grassy country. 20. ARTAMUS LEUCORHYNCHUS (Horsf.). Leptopteryx leucorhynchos, Horsf. Tr. Linn.
