38 LOTSY AND KUIPER, A PRELIM. STATEMENT OF THE RESULTS OF MR. 
nes of black extending down the vane. All the remaining upper pluma- 
ge, together with the wingcoverts and visible portion of the seconda- 
ries, is a fine mottling or vermiculation of sandy or rufous brown and 
black, the back, the lesser and median coverts with a conspicuous, hair- 
like white shaft-streak. Primaries pale dull brown. Tail-feathers black, 
slightly glossed with greenish, the central pair with a marginal mott- 
ling of reddish-brown. The face is covered with a scanty growth of 
brown featherlets, the chin and throat with a somewhat denser pluma- 
ge of white. The pattern of the ventral plumage is a central area of 
white and a wide black or dark-brown border. The white increases pos- 
teriorly, until on the mid-belly it obliterates the dark marginal color. 
There is considerable mottling however of the white area, in the form 
of two irregular longitudinal lines in the centre of the vane. The under 
tail-coverts are dark-brown, with a small; terminal, white shaft-spot. 
The comb is very rudimentary, 3 or 4 mm. in height, slightly not- 
ched. The spurs are short, rounded nodules. Upper mandible dark hor- 
ny-brown; lower yellowish white. [rides red to yellow; facial skin red- 
dish, never as bright as in the cock. Legs and feet brownish-yel- 
low, darker on the toes. 
Length 380 mm.; culmen from nostril, 19; wing 200; tail 145; tarsus 
63; middle toe and claw 50 mm. Weight 1 Ib 9 ozs to 1 Ib 12 ozs.
