IHs, 1877, Xotc on the Pellorneum tickelli of Bhjfh. By Akthue, Marquis of Tweeddale, M.B.O.U. 

 P- ^^^- [From ' The Ibis,' October 1877, Plates X. & XI. in orig.] 



Since I addressed a letter relating to this species to the Editors of ' The Ibis ' on the 26th of 



April (Ibis, 1877, p. 385)*, I have received from Tenasserim specimens of true Pellorneum tickelli, 



obtained at Meetan by Mr. Limborg. These have been compared by Lieut.-Col. Godwin-Austen 



with Blyth's type, still extant in the Calcutta Museum, and identified by him as belonging to 



Blyth's species. These examples enable me to state that Blyth's identification of P. tickelli with 



P. snbochraceum, Swinhoe (B. of Burma, no. 359), is erroneous. I am unable even to class 



Ibis, 1877, P. tickelli under the genus Pellorneum, although in his original description (J. A. S. B. 1859, 



^" p. 414) Blyth described it as being a typical Pellorneum in structure. It seems to me to fall 



more nearly under the genus Drymocataphus. On comparing the type of Dri/mocafaphusfulvus, 



Walden (Ann. & Mag. N. H. ser. 4, xv. p. 401) f , with true P. tickelli, 1 find that my species
