unarmed. Rest as in Mierotarsus ; the head being crestless, and the 

 coronal plumage uniform in texture with the other feathers. The 

 lower tail-coverts of the only ascertained species are bright yellow, as 

 in various species of Pycnonotus. 

 Ix. cyaniventris, (nobis,) J. A. &,XI, 792 : Turdus, No. 6, Raffles, Lin. 

 Trans. Xllf, 311. Common in the vicinity of the Straits of Malacca. 



The next is a very remarkable group, which begins now to ex- 

 hibit a variety of species, and of generic modifications of form, which 

 will ultimately indicate its true place in the system. Not long ago, 

 its only ascertained representative was the Paradoxornis flavirostris of 

 Gould : but the following may now be referred to it. 



1. Conostoma cemodius, Hodgson, J. A. S. X, 856. Nepal. 



2. Paradoxornis flavirostris, Gould, P. Z. S, 1836, p. 17; Mag. ZooL 

 and Bot. 1838, p. 513 ; Icones Avium, pi. VI : Bathyrhynchus brevi- 

 rostris, McClelland, Ind. Rev. 1838, p. 513. Especially characterized, 

 generically, by the deep sinuation of the tomise of its mandibles. Hab. 

 Eastern Himalaya, and the mountains of Assam. 



3. Heteromorpha unicolor, Hodgson, J. A. S., XII, 448. Nepal. 



4. H. ruficeps ; Paradoxornis ruficeps, nobis, J. A. S., XI, 177. 

 Bootan mountains, and those of Arracan : Darjeeling. 



Chleuasicus, nobis, n. g. Nearly allied to Suthora, Hodgson (Ind. 

 Rev. 1838, p. 32, and J. A. S. XII, 449/, from which it is dis- 

 tinguished by the considerably larger proportionate size of the legs, 

 and by the rather larger and decidedly broader bill, the outline of which 

 (as seen laterally) is still more tumid and anomalous-looking. Rest as 

 in the other genera of the group. 



5. Chi. ruficeps, nobis. Length five inches and a half, of which the 

 tail measures two and three quarters ; wing two and five-eighths ; bill 

 to forehead (through the feathers) three-eighths of an inch in a straight 

 line ; and tarse seven-eighths ; the latter, with the toes and claws, 

 thicker and stouter than in Suthora. Colour as in my Heteromorpha 

 ruficeps, but the under-parts white, or less tinged with rufescent : i. e. 

 the head and neck are bright ferruginous ; the rest of the upper parts 

 olive-brown, more or less inclining to ferruginous, especially towards 

 the shoulder of the wing ; and the entire under-parts are white : bill 

 whitish horn-colour, apparently tinged with green in the recent spe- 

 cimen ; and the legs appear to have been greenish-plumbeous. From 

 Darjeeling.
