Coloration. Forehead and two thirds of the crown white; the remainder of the head, neck, breast, back, scapulars, and wings black, the scapulars and the greater coverts broadly tipped white, the secondaries and tertiaries white at their bases, and the later ones tipped white ; rump, upper tail-coverts, abdomen, vent, under tail-coverts, under wing-coverts, and axillaries white; the two outer pairs of rectrices entirely white ; the next black, with white base and tip ; the others black, tipped white.

The nestling has the head, neck, and back chocolate-brown, the sides of the head with pale shafts ; chin and throat grey ; breast brown, with yellowish streaks ; the other parts as in the adult; the white of the crown is assumed at a late period.

This species is slightly smaller than H. sinensis, Gould, from China, and is inseparable from it in Coloration. The two species may, however, be always separated by the structure of the tail. In H. leschenaulti the outermost tail-feathers are about as long as those next to them, whereas in H. sinensis these feathers are shorter than the penultimate pair by about two inches.
Distribution. Sikhim ; the Bhutan Doars ; Upper Assam ; the Daphla hills ; the E. Naga hills; the Khasi hills; Manipur; the northern and central portions of Tenasserim below 2500 feet. This speciess in occur Java.
