Ackeen. 459 



tlie other hand has the three exterior feathers white, all three of 

 them with a gradually increasing- dusky or blackish patch on 

 the inner web, while the fourth feather is black, with the excep- 

 tion of a narrow white tip and a tongue of white running up 

 from this along the shaft on the outer web for about an inch or so. 

 The following are the dimensions taken in the flesh of a female : 



Length, 8-75 ; expanse, 12-5 ; wing, 3-75 ; tail, from vent, 

 8*5 ; tarsus, 1-15 ; bill, from gape, 1-05 j weight, 1*75 ozs. Bill, 

 black ; legs and feet, horny. 



Mr. Davison notes : " I only saw this bird once ; a pair were 

 together in a dry ditch where they were apparently looking for 

 insects among the dry leaves that had there accumulated." 



Suya albogularis, Sp. Nov, 



This is a very distinct, and I believe unquestionably new 

 species. My Yarkand S. albositperciliaris was not, as I stated at 

 the time, a thoroughly typical Sui/a ; the present is an 

 eminently typical species ; it is closest to atrogularis, but may 

 be distinguished at once from that species by its much larger 

 bill, its conspicuous though narrow, pure white supercilium, and 

 by its white chin and throat, the feathers white to their bases. 

 Fine specimens of atrogularis also exhibit a supercilium, but it is 

 always a dingy brownish white; again at one stage of its 

 plumage, atrogularis has the chin, throat, and breast, dingy brown- 

 ish white, but the basal portion of the feathers in this species 

 is always dusky or blackish, whereas in the Sumatran bird, they 

 are white. The tarsi also are somewhat stouter than those of 

 atrogularis. The upper plumage is very close to that of 

 atrogularis, but is somewhat greyer on the head and more 

 rufescent olivaceous on the baek and rump. The ear coverts in 

 the present species are grey, the shafts faintly albescent, so as to 

 produce a slightly striated appearance. 



The dimensions of a female of this species taken in the flesh 

 are as follows : 



Length, 7; expanse, 6-25 ; wing, 1-82 ; tail, from vent, -^3-6; 

 tarsus, 0-8; bill, from gape, 0-65; weight, nearly 0*5 ozs. 



L-is, red brown; legs and feet, earneous ; bill, dark horny, 

 tinged pinkish on lower mandible. 



Mr. Davison says : " I met with this bird at a village on the 

 East Coast of Acheen, in a small party of about six or eight, 

 among a thick growth of nettles : they were keeping up a 

 continual note like a very subdued " rattle of the bones." 

 Occasionally, one would work his way to the top of a plant and 

 rattle louder than his companions, disappearing the moment 

 he had finished. On shooting one, the others became quite
