of water. Schisfacews is 10 inches in length, and is easily recognised. 
Colour is slaty in appearance, which replaces the black on upper 
parts, observed on the foregoing birds. Above, the plumage is 
darkish slaty blue, on the head, neck and back ; black on cheeks and 
throats ; white frontal band over the forehead, typical to this 
family; underparts are white; wings and tail black with white 
spots; a big glistening wing patch or band, shows out conspicu- 
ously. These birds are generally found in the beds of our bigger 
mountain streams, occasionally in company with Plumbeous Water- 
Robin, when this bird descends to a lower elevation. 
(587) Enicutus Scoviert, Short-tsiled Fork-tail, looks a_ bit 
comical with its small tail, in presence of the foregoing species, 
with their long train like tails, otherwise it is similar to them in 
many respects. Scoulert are rare. A better opportunity is offered, 
of seeing this bird on the dry shingly bed of Rungeet, Big Rungeet 
in particular, where it enters the river basin in Sikkim. 
Scouleit appears to delight to hunt for aquatic insects on the 
rocks, amidst the noise and turmoil of our hill torrents and water- 
falls. In size it is 53 inches; plumage, above, is not unlike maculatus, 
tail and wings are black with white patches ; rump and upper tail 
coverts white ; head aud back are black, the former with a white 
frontal band : throat and part of the breast black, remaining por- 
tions, below are white.

hardly necessary. They are more partial to watery surroundings

and pointed Ist and 2nd quills the longest, tertiaries equal to the 
primaries ; tail longish and slender; tarsus moderately long and 
thin ; hind toe and claw short.
