BIRDS OF TENASSERIM. 135 



succession, producing a vapid roll as is the case with M. pulveru- 

 lentus and C. sultaneus. I can add nothing to Captain Feilden's 

 excellent account. — W. D.]

Laynah ; Bankasoon ; Malewoon. 



Confined to the southernmost district of the province. 



[In all its habits, the localities it frequents, voice, &c, this 

 species resembles exactly the last. — W. D.] 



Malherbe doubted the occurrence of this species in Tenas- 

 serim, but south of Mergui it is not uncommon. I have already, 

 S. F., III., 67, pointed out briefly how this and the allied 

 Indian Black Woodpeckers differ. The only Burmese species 

 with which this could be confounded is crawfurdi (S.F., III., 66), 

 which is distinguished at once by its white rump, and by the 

 great amount of white on the inner webs of the primaries. 



The present species varies a good deal in size ; the birds pro- 

 bably take some years to attain their full dimensions. 



Males. — Length, 15-5 to 17 75 ; expanse, 26 to 28'25 ; tail, 

 5-29 to 7-26 ; wing, 8'75 to 9'2 ; tarsus, 1'25 to 1'35 ; bill from 

 gape, 2*25 to 2 6 ; weight, 8 to 12 ozs. 



females. — Length, 16"25 to 18"12 ; expanse, 26 to 28'5 ; tail, 

 62 to 7-5 ; wing, 8-5 to 9-4 ; tarsus, 1*25 to 1*45; bill from 

 gape, 2 '2 to 2*35 ; weight, 8 to 12 ozs. 



Legs and feet pale plumbeous to leaden blue ; iris creamy 

 white^ creamy yellow, clear yellow ; orbital skin very dark plum- 

 beous ; bill black ; lower mandible plumbeous blue to dusky 

 plumbeous. 



In the males the forehead, crown, occiput and occipital crest, 

 and a broad patch on either sides at the base of each mandible are 

 intense crimson. In the female these patches are wanting, and 

 the forehead and crown are black. Excepting the red positions, 

 the entire upper surface of the bird, tail, sides of the neck, and 

 breast are black ; the upper plumage, in fine specimens, with a 

 certain amount of a bluish or greenish lustre ; the chin and 

 throat and front of the neck, except at the base, black, speckled 

 with white ; the sides of the head are black, but there is a 

 little white speckling immediately behind the ear-coverts ; 

 the entire abdomen, sides, and flanks are pale yellowish crea- 

 my ; the lowest feathers of the breast are tipped whitish ; the 

 lowest feathers of the abdomen, flanks, and tibial plumes have 

 a blackish brown, more or less cordate spot near the tip ; the 

 lower tail-coverts are black. The primary lower wing-coverts 

 black ; the lowest of them greyish brown ; the rest of the wing- 

 lining creamy white.
