20. Cactornis pallida Scl. and Salv. ? (C. hypoleuca, sp. nov., if distinct.*) 



A single specimen from James Island seems to come very near to G. 

 pallida Scl. and Salv., but it is apparently larger and lighter colored, 

 C. pallida being described as Laving the upper parts olive brown and 

 the lower parts pale ochraceous, whereas the bird in hand is light 

 grayish olive above and dull white beneath. M. Sharpe, however, in 

 describing the type specimen says (Cat. B. Brit, Mus., xn, p. 20) that it 

 is "pale olive-brown " above and the " cheeks, throat, and under surface 

 of body white, slightly washed with olive yellow, with a few dusky 

 streaks on the chest," which very nearly agrees with the James Island 

 specimen. The difference in measurements is shown below :
