 The crown is ratlicr more ashy than the back, but is not 

 black as in the two examples from Sinkat collected in 

 March. All the others have the characteristic vinous flush 

 on the underside.

 Very common on the Red Sea coast during the spring 

 migration, widely distributed in winter from Khartoum to 

 -Lado. It is not rare in winter on the scrubby desert west 

 of Omdurman and along the Nile north of Khartoum 

 {A.L.B.).

Heuglin (Orn. N.O.-Afr. i. p. 303) states that he met 

 with this bird on migration in the Bayuda desert, Dongola 

 Province. He named it Sylvia melanocephala minor, which 

 is identified by Hartert with S. m. momus. It was also 

 procured by Messrs. N. C. Rothschild and WoUaston at 

 Shendi (Ibis, 1902, p. 17). 



There are no Sudanese examples in the British Museum.

We are inclined to regard all the Willow-Wrens collected 

 by Butler as belonging to the slightly greyer eastern race.
