1885. J DURING THE VOYAGE OF THE YACHT 'MARCHESA.' 263 



species after Mr. Kettlewell, whose adventurous voyages in the 

 yacht Marchesa have done much to help the science of Ornitho- 

 logy. 



32. CopsYCHUS MiNDANENSis (Gmelin). 



Le Merle de Mindanao, Month. Hist. Nat. Ois. iii. p. 387. 



Copsychus mindanensis, Wald. Tr. Z. S. vol. ix. part 2, p. 194. 



Hab. Zebu, Guimaras {Meyer); Luzon and Basilan {Everett); 

 Negros {L. C. Layard); Mindanao {v. Martens); Sa\\i{Guillemard); 

 Borneo (?) {Salvadori). 



a, b. S • Sulu Island. 



Iris brown ; bill and tarsus black. Length 20-5 centims. ; wing 

 9"4-9'7 centims. Under wing-coverts entirely black. 



33. Gerygone flaveola, Cabanis. 



Gerygone flaveola, Cab. J. f. O. 18/3, p. 15/ ; Cat. B. vol. iv. 

 p. 214, pi. V. fig. 2. 



Hab. Celebes {Meyer) ; Borneo {Schwaner, Mus, Lugd.) ; Sulu 

 {Guillemard). 



a, c? • Sulu Island. 



b, $ . Sulu Island, 

 e. Sulu Island. 



Iris brown ; bill and tarsus blackish. Length of wing 5*2 centims. 



A comparison with skins of G. flaveola from Celebes in the British 

 Museum shows the present individuals to be considerably paler on 

 the under surface, which is a washy straw-yellow in colour. The 

 ear-coverts also are of the same colour as the head, without any 

 shade whatever of yellow. These Sulu birds appear, therefore, to 

 be intermediate in form between G. flaveola of Celebes (and Borneo ?) 

 and G. simplex of Luzon, the latter bird being white beneath, 

 washed with buff on the breast, and having the ear-coverts a 

 uniform ashy brown. The present series approximate G, simplex 

 in their admeasurements. 



34. CiSTicoLA ExiLis (Vig. et Horsf.). 



Cisticola exilis, Sharpe, Ciit. Birds, vol. vii. p. 269. 



Cisticola grayi, Tweedd. P. Z. S. 1877, p. 828. 



Cisticola semirufa, Wardlaw Ramsay, Orn. Works, Tweedd. p. 057 

 (1881). 



Hab. Luzon ; N. Mindanao {Everett) ; Sulu {Guillemard). 



a-c, S • Sulu Island, April. 



d, $ . Sulu Island, April. 



Iris brown ; bill and tarsus flesh-colour. The head in all is more 

 or less striped. Length about 9*0 centims. ; wing 4*4 centims. 

 This species was common in Sulu in the grassy opens, to which it 

 appears entirely confined. 



In the correct identification of this as well as of several other 

 species, I have had the kind assistance of Mr. Bowdler Sharpe. As 

 far as I am aware, it has not been recorded either from Borneo or
