2. "Iris brow n -hazel ; upper mandible j)lumbeous green, 

 lower greenish horn ; feet greenish." 



The bird is rare in the north and only just reaches British 

 India at Bankasoon, Tenasserim.

4 6 ad., 1 2 vix ad., 1 ? juv. Hat Sanuk, nr. Koh Lak, Rajaburi, 

 S. W. Siam, 12-18 April 1919 (Nos. 5250-1, 5254, 5372, 5387-8). 



Male adult, " Iris red, orbits sage ; bill greenish ivory, whitish 

 at tip; feet greenish slate." Female. " Iris red, orbits dark sage: 

 bill greenish ivory, paler at tip ; feet greenish slate." 



Total length d, 322, 336, 355, 317 ; 9, 328 ; wing 6, 167, 160, 

 159, 158; 9, 156; tail d, 125. 137, 123, 128; 9, 127; tarsus, 6, 26, 

 26, 29, 27 ; 9, 25 ; bill from gape 6, 43, 42, 47, 39 ; 9, 40 (app.)mm. 



The four males agree well with the type, especially in the 

 amount and tint of the yellow on the throat : the area immediately 

 beneath the stripes on the throat is, however, darker, and the white 

 edgings creating the striped effect are narrower : in one specimen the 

 lores are almost uniform with the forehead, having hardly any white. 



The not quite adult female ditters from the male in having 

 the malar stripes and chin rufous, not pale yellow ; and in having the 

 lores and ocular region more extensively mottled with white. 



Mr. Baker (hoc. cit.) has gone badly astray in considering these 

 birds as identical with pierrel, of which we have now a large series, 

 including actual topotypes. Those differ in being on the whole even 

 paler below than our Koh Lak birds : the yellow malar stripes are 

 more restricted and so is that colour on the chin. Even in quite 

 adult birds the white edgings to the black feathers of the throat are 

 narrower and mixed with rufous, which is quite absent in Ch. f. lylei. 

 The colour of the bill, which is important in woodpeckers, also con- 

 firms the distinction.
