melia leucotis, Strickl. The principal differences between the 
two species appear to be :—first, the throat being white in 7’. 
guttatus, while it is black in 7. leucotis; and, secondly, the - 
breast being ash-coloured in the Malaccan bird, and rufous 
(orange-rusty), like the abdomen, in 7. guttatus. Colonel 
Tickell’s species was described and figured from a female ; but 
he describes the male and female as being alike in plumage ; 
yet, although he shot what he presumed to be the male, he 
did not succeed in finding it. The form of the bill in the 
genus Turdinus is so dissimilar to that of Timelia leucotis 
that is difficult to assume that Blyth would refer a species 
like Timelia leucotis to his genus Turdinus. Still, in Colonel 
Tickell’s plate, the bill resembles that of a Timelia rather than 
that of a Turdinus; nor is the plumage that of a Turdinus. 
Turdinus brevicauda (so written by Colonel Tickell) is too 
highly coloured; and the spots on the tips of the tertiaries 
and greater wing-coverts are described and figured as being 
white, whereas in all the examples I have seen these spots 
are rusty fulvous, and in the excellent figure of the species 
given by Mr. Gould (B. As. pt. 24) they are so coloured. 
It may be that the Tenasserim type species differs from that 
inhabiting the Khasias. As some excuse for describing the 
Khasia bird as new under the title of 7. striatus, I may be 
permitted to state that I did so at Dr. Jerdon’s request, and 
that when he gave me the specimen which I described (Ann. 
N. H. (4) vu. p. 241) from, he assured me that it was new. 
Lieutenant Wardlaw Ramsay discovered Sibia picaoides 
at an elevation of 5000 feet in Karennee (Blyth, B. Burma, 
no. 319); and its occurrence in Burma had not been pre- 
viously made known; but Colonel Tickell, who figures the 
species from a Darjeeling example, mentions that he killed it at 
an elevation of 8000 feet in Tenasserim, and that “ it inhabits 
the whole Eastern Cis-himalaya and along the Malayan spur.” 
His plate represents the colouring of much too pale a tint. 
In February 1859, on the plateau of Mooleyit, in Tenas- 
serim, at an elevation of 6600 feet, Colonel Tickell discovered 
a species of Sibia, which has not, so far as I know, been again 
obtained. One example, that of a male, was secured; and on
