The Short-toed Calandra Lark winters in the deserts 

 of the Soudan in large flocks, being perhaps numerically 

 the most abundant of all our migratory birds. It becomes 

 plentiful near Khartoum about the middle of October (it 

 appeared in 1902 on the 18th), and is still common at the 

 end of March.

Mr. Hawker's M. marginata has been shown by Messrs. 

 Ogilvie-Grant and Reid ('Ibis/ 1901, p. 628) to have been 

 founded on a bright, freshly moulted example of this species. 



16. MlRAFRA CORDOFANICA Stlickl. 



a. ? . Urn Bosha, May 5, 1904. 



b. 2 . 



I have met with the Kordofan Bush-Lark only on 

 the road from El Duem to El Obeid, where, from Hashaba 

 to Um Bosha, it is common on the red sandy soil 

 among " Heskanit " grass. The cream-coloured margins 

 of the feathers of the upper plumage are bright and con- 

 spicuous in newly moulted examples, but later are partly 

 lost by abrasion. Capt. H. N. Dunn obtained the bird at 

 the Agageh Wellsj Western Kordofan, in November 1902.
