Sm,— Captain Hayes Lloyd, in an interesting letter (Ibis, 1872, p. 197) has stated his conviction 



to be that Cyornis tickellioe, Blyth, is the female of Cyornis jerdoni, G. R. Gray (olim 



C. hamjmnas, Horsf., apud Jerd.). Captain Lloyd's observations were made in a part of India 



ornithologically little known ; and it is therefore not impossible that the Cyornis he refers to is 



distinct from either of the species he has associated it with. But for my present purpose it is Ibis, 1872, 



sufficient to assume that the Cyornis of Gujerat does belong to one or other of the above-named P' 



species. 



There can be little doubt that the birds Captain Lloyd describes are male and female of one 

 and the same species ; for Dr. Jerdon's surmise that the female of C. jerdoni {=C. banyumas, ap. 



Jerd.) is olive, has not been sustained by subsequent investigation. On the contrary, the females
