BUTALIS MUTTUI. 



Butalis muttui, Layard^ Ann. & Mag. N. H. ser. 2, vol. xiii. 

 p. 127. 



Alseonax terricolor, Holdswortb, P. Z. S. Cat. no. 122, 

 p. 441 ; Legge, Str. Feath. vol. iii. 1875, p. 366. 



On comparing the Ceylonese Rusty Flycatcher, several 

 examples of which I possess, with specimens of Alseonax 

 ferrugineus in the British Museum, I find that it is quite dis- 

 tinct from the latter bird ; and as Mr. Sharpe informs me 

 that it is not known at present from any other locality but 

 Ceylon, it must be returned to the list of birds peculiar to 

 the island, among which it was originally placed, when de- 

 scribed by Layard. I cannot but think, however, that it has 

 some other habitat besides Ceylon ; for it appears to me to be 

 migratory to that place, inasmuch as I have only observed 

 it during the cool season — October to March*. Layard^s 



* Layard, however, got his specimen in June at St. Pedro, which mili- 

 tates against my theory.
