identical with birds procured by Mr. Stalker in Ceram, and 

 probably the type also came from that island. The type of 

 P. griseonota is no doubt a fully adult bird and almost 

 certainly a male. In Mr. Stalker's series, three of the most 

 adult males have lost all traces of the darker shaft-streaks 

 on the sides of the throat and fore-neck, four males and one 

 female are faintly streaked on the fore-neck, and two females, 

 possibly younger birds, are strongly streaked on the throat, 

 fore-neck, and chest. The species of this dull-coloured group 

 of Pachycephala are extremely local ; in Bouru we find 

 P. examinata, Hartert, in Sula P. lineolata, Wallace, and in 

 Ceram P. griseonota, G. It. Gray. 



For further remarks on these species, cf. Hartert, Nov. 

 Zool. v. pp. 131-132 (1898). 



Mr. Ooilvie-Grant also described a new species of Wren- 

 Babbler from Tenasserim and a new species of Sibia from 

 the Malay Peninsula : — 



TURDINULUS DAVISONI, Sp. n. 



Turdinulus exsid,* Grant (nee Sharpe), Ibis, 1896, p. 60 

 (Thoungyah and Mt. Mooleyit) . 



Turdinulus murinus, Hume (nee Blyth), Stray Feath. ix. 

 p. 115 (1880) ; Oates, B. of Burmah, i. p. 62 (1883) [except 

 description of type]. 



Adult male and female. Easily distinguished from T. exsul, 

 Sharpe, to which it is most nearly allied, by having the 

 cheeks and sides of the throat washed -with rust-colour, and 

 the underparts more olive-brown, much less suffused with 

 rufous, and distinctly streaked with whitish. Measurements 

 as in T. exsul. 



Hab. Tenasserim. 



Obs. In my paper quoted above I pointed out the dis- 

 tinguishing features of this species, but, owing to lack of 

 material from the Malay Peninsula and Borneo, refrained 

 from giving it a name. A subsequent revision of these birds, 

 and an examination of the series of T. granti from the Malay 

 Peninsula recently procured by Mr. Robinson, show that
