the neighbourhood of Bh;imo ; Arrakan ; Pegu, probably not 

 extending to the east of the Sittoung river. This species is found 

 at low elevations chiefly.

 the side of a nullah in the Pegu hills on the 20th April, and con- 

 taining three fresh eggs.

Coloration. Porehead 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. 



Length about 11 ; tail up to 5-9 ; wing up to 4*5 ; tarsus 13; 

 bill from gape 1*1. 



This species is slightly smaller than //. 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 

 //. leschenaulti the outermost tail-feathers are about as long as 

 those next to them, whereas in //. sinensis these feathers are 

 shorter than the penultimate pair by about two inches. 



Distribution. Sikhim ; the Bhutan Doars : Upper Assam ; the 

 Daphla bills ; the E. Nu'ga hills ; the Khasi hills; Manipur ; the 

 northern and central portions of Tenasserim below 2500 feet. 

 This spociess in occur Java. 



Genus HYDROCICHLA, .Sharpe, 1S83. 



This genus differs from Henicurus in having the tail about equal 

 in length to the wing, and the middle pair of tail-feathers about 

 half the length of the tail. There are two species of this genus 

 found in India, in one of which the sexes are alike and in the other 

 dissimilar.
