51. Lagonosttcta butleri Grant. 

 a. ?. ChakChak, 15.2.07. 



*. ?. 



Fairly common in the forests from Wau to Chak Chak. 

 I could have procured a good series had I known that the 

 species was new, and it was rather a surprise to me that it 

 proved undescribed. (See Grant, Bull. B. O. C. xxi. p. 16.) 



52. Pytelia citerior Strickl. 



a. S ' Chak Chak Road, 12. 2. 07. 



b. ? . Pongo River, 5. 2. 07. 



This Red-faced Finch was seen at most places where there 

 was thorn-bush from Meshra to Chak Chak. 



In the male specimen the red on the head surrounds the 

 eye ; there is no trace of the white bars becoming spots on 

 the crop ; the under tail-coverts are unbarred white ; the 

 flanks are barred with olive-brown and have a greenish 

 suffusion. 



In the female there is dull orange-red patch on each side of 

 the forehead between the eye and the nostril ; the chin and 

 throat are ashy grey ; the under tail-coverts are unbarred 

 white. 



This is much the most widely distributed form of Pytelia 

 in the Soudan. 



53. Pytelia soudanensis Sharpe. 

 a. (J . Bor, Upper Nile, 7. 5. 06. 

 Collected for me by Mr. G. B. Middleton. 



The red on the head only reaches to the front of the eye ; 

 there is rather more red on the throat than in P. citerior 

 Strickl. ; the white bars become twin si^ots on the crop ; the 

 flanks are white, more heavily barred with blackish brown, 

 and with no greenish tinge ; the lower tail-coverts are barred 

 with browu. 



The type of Pytelia jessei Shelley, which I examined in 

 the Natural History Museum, appears to me identical with 

 this bird. 



54. Ploceipasser superciliosus (Riipp.). 



a. ? . Chak Chak Road, 11.2. 07. 



b. S- Khor Gitti, 24. 3.07.
