240 NOTES UPON A COLLECTION OF BIRDS MADE 



504.— Adelura (Ruticilla) cceruleocephala, Vigors. 



Not uncommon in the upper parts of the valley among the 

 pine woods. This species does not quiver its tail as all 

 Redstarts do, and its manners and habits differ from those of 

 the true Redstarts. It is a Wood-chat, but differs considerably 

 in structure from Pralincola. In manner and notes it put me 

 much in mind of Iantliia rufilata; and the differences are so 

 slight, that it might very well stand in that genus. 



505.— Rhyacornis fuliginosa, Vigors. (" Ruticilla 

 juliginosa") 



Common on the Bhamruttee. 



506. — Chsemorrornis leucocephala, Vigors. 



Not uncommon from Danguli to Derail. 



507. — Larvivora super ciliaris, Jerdon. (L. cyana, 



Hodgs.)* 



This species was most numerous at Suki. It affects thick 

 cover, and is as much addicted to hiding itself from human 

 observation as Cyornis rubeculoides. 



508. — Ianthia rufilata, Hodgson. 



This bird is more numerous in the upper part of the valley 

 than in the parts of Cashmere that I visited. Its call note, or 

 alarm note, whichever it may be, is Robin-like, and its manners 

 are much those of a Robin. I did not hear the song, if it has 

 any. It is a very shy bird. Some of the males that I shot 

 were (as in Cashmere) in the female plumage. These were 

 also breeding males, as proved by dissection. This appears as 

 if the blue plumage were not assumed after the first moult, 

 supposing the Ianthia nestling to be spotted as most of these 

 birds are. The changes the various Warblers are subject to, 

 and the time when these changes take place, are interesting 

 questions ; and we have much to learn concerning them. I 

 used to think that the first moult of a Warbler produced the 

 adult plumage ; but in the cases of Ianthia and Siphia this cannot 

 be the case. I refer to Siphia leucomelanura, for with the 

 others, in life, I am unacquainted. 



* Hodgson's name, which is cyanea, and not cyana, has, I think, precedence, and 

 should stand. The nearly allied species so common in Eastern Siberia and China, 

 and, as we have recently found, in Northern Tenasserim, is cyane, Pallas {^gracilis, 

 Swinh). Cyane does not, I think, extinguish cyanea, — Ed.
