292 NOTES. 



not here access, and this comparison Mr. Brooks, who will 

 take home one of my white-bellied Burmese birds, promises 

 to make. 



Amongst the specimens in Mr. Mandelli's collection I 

 find three Laughing Thrushes collected for him by some 

 gentleman in Captain Hill's survey party, according to the 

 tickets, in Tenasserim, and apparently on the frontier hills 

 between Tavoy and Siam. 



These specimens were labelled G. belangeri by Mr. Mandelli, 

 and no doubt they beloug to the same little group as G, leuco- 

 lophus of the Himalayas and Aracan,*' G. belangeri of Burmah, 

 and G. bicolor, Mull., of Sumatra ; but it is clearly the Garrulax 

 leucog aster of Walden, described by him, P. Z. S., 1866, 

 p. 548, from a specimen received by him from some part of 

 Siam. 



As this species must probably now be included in our list 

 (it would stand as 4tQ7ter) a brief description of it is necessary. 



Dimensions (taken from the skin) : — Length, from 11*5 to 

 12*5; win or, 5'0 to 575 ; tail from insertion of feathers, 5'0 to 

 5*5 ; tarsus, 1*6 to 1*8 ; bill straight from frontal bone to tip, 

 1-1 to 12. 



Bill black ; legs and feet apparently have been dark plum- 

 beous. The lores, cheeks and ear-coverts velvet black, as in 

 leucolophus and belangeri; entire cap white, and head fully 

 crested, but the crest not quite so large or conspicuous as in 

 these two species ; the tips of the longest crest feathers 

 slightly shaded with grey ; a broad grey half collar on the 

 back of the neck ; the feathers along the middle of the back 

 of the neck, with rufous olive shafts, and a little shaded on 

 the webs on either side with this same colour ; mantle bright 

 ferruginous, brighter, i.e., not so deep, as in belangeri, becoming 

 rusty olive on the rump and upper tail-coverts ; wings 

 precisely as in belangeri; the inner webs dark hair brown ; the 

 outer webs olivaceous, with a yellowish ferruginous tinge ; 

 tail deep hair brown, obsoletely barred, and the central feathers 

 and the outer web3 of the laterals faintly shaded, except just 

 at the tips with a duller shade of the colour which suffuses 

 the outer webs of the quills ; chin, throat, breast, abdomen 

 pure white ; sides, flanks, lower tail-coverts, and outer tibial 

 plumes rusty olivaceous brown, much the same colour as the 

 wino-s ; the basal portions of the lower tail-coverts are greyish 

 white, and the interior tibial plumes are white, faintly tinged 

 with the colour of the outer tibial plumes. The grey half 

 collar just runs up to and meets the tips of the black ear- 

 coverts.
