distitigtienda. Long, tota 5-7, culminis 0-5, ate 3-1, caudm 2-8, 

 tarsi 0.7. 



General colour above olive-yeUo-«dsh, the wing-coverts like the 

 lack ; quills and tail dull blackish brown, externally washed with 

 olive-yellow like the back, the greater coverts also brown washed 

 with olive-yeUow ; tail-feathers paler bro-mi at the tip of the inner 

 web ; head crested, black, as also the sides of the face, ear-coverts, 

 and cheeks ; entire under surface of body yellow, slightly more 

 olive-green on the sides ; under wing-coverts yellow, the longer ones 

 white washed with yellow ; quills sepia-brown below, white along 

 "the edge of the inner webs. 



This species is almost exactly the same as Ruligula atricapilla of 

 Ceylon, but has not the white tips to the tail-feathers, while its long 

 crest distinguishes it from the Ceylonese species, which is not 

 crested. In the form of the crest and in general appearance it is 

 almost precisely similar to B. flavivmtris of Pegu and Tenasserim, 

 but is smaller, and has the throat yellow like the rest of the under 

 suriace. The single specimen obtained was in Mr. Treacher's 

 collection. 



14. ftllNIGER RUFICRISSUS, sp. n. 



C. similis C. gutturali, sed supra ubique sordidior, swpracaudalibus 

 caudaque saturate rufescenti-hrunneis ; loris et regione oculari 

 cum genis et regione parotica sordide cuiereis, gula alia, corpore 

 reliquo subtus sordide olivascente, suh caudalibus eastaneis. Long, 

 tot. 8, culm. 0'85, ate 4-0, cauda 4'0, tarsi 0'7. 



This species is not very different from C. gutturalis, but differs in 

 its much darker coloration, especially on its under surface, which is 

 dull olivaceous, with a white throat and chestnut-red under tail- 

 coverts. There is an entire absence of the pale-brown colour of the 

 breast washed with yellow, and of the light yellow abdomen and 

 pale fawn-coloured under tail-coverts. The crest is very long in 

 C. rufierissus, and extends nearly to the mantle. 



15. Ianthocincla treacheri, sp. n. 



I. similis I. mitratse {S. Mull.), ex Sumatra, sed genis, mento et 

 regione pa/rotica sicut caput eastaneis facile distinguenda. Long, 

 tota 10, culminis 0'85, ate 4-15, caud(B 4'5, tarsi Vo. 



Adult. General colour above dark ashy grey, with a very slight 

 shade of ochraceous imder certain lights ; the wing-coverts slightly 

 more bluish grey than the back : quills blackish, externally bluish .
