150. FuLiCA ATKA. (('((111111011 Coot.) " Ghuvra,'' Arab. 

 Common about Tugg-uvt. Its congener, Fulica cristata, a])- 



pears to be continod to a few northern lakes on this side tlie 

 Atlas. 



151. Anser segetu.m. (Bean Goose.) " Onzn," Arab. 

 I saw one at Temayin recently shot. 



152. Casarca rutila. (Ruddy Shieldrake.) 



Hundreds of these birds resort to the salt-lakes of Bou Gui- 

 zoun, Waregla, Tuggurt, &c. AX Bou Guizoun I captured some 

 half-dozen nestlings of various ages in the downy state, some of 

 them scarcely more than a day old ; and yet the only place where 

 they could possibly have bred, and where we had procured a nest 

 three days previously, was a range of cliffs more than twelve 

 miles distant. This was in May 1856. 



153. Tadorna vulpanser. (Common Shieldrake.) 



A few at Tuggurt, but not nearly so abundant as Casarca ru- 

 tila. Elsewhere I did not observe it until our arrival at Djendeli, 



154. Anas boschas. (Common Wild Duck.) 



155. Chaulelasjius streperus. (Gadwall.) 



156. Rhynchaspis clypeata. (Shoveller.) 



157. Querquedula crecca. (Teal.) 



158. Dafila acuta. (Pintail.) 



159. MaRECA PENELOPE. (Wigcou.) 



All of these were more or less frequent wherever there was 

 water.

 Occasionally procured in the Wed R'hir and at El Aghouat.
