82 Mr. J. H. Gurney, Jiin!, on the Ornitholotjy of Algeria. 



sued. I think its flight is even slower than a Stouechat's ; and 

 it seldom flies far without perching on a stone, clod, or small 

 bush, where it moves the body u]) and down like R. phoenicura. 

 R. moussieri jerks the tail sometimes, but never so rapidly as 

 R. phomicura. When feeding, it digs its bill into the ground 

 very frequently, and looks round after each dig, with the pert 

 air of a Robin. They pair in March ; and the males look 

 very pretty as they chase the females among the bushes and 

 rocks. As this bird occupies such a dubious place between 

 the Chats and the Redstarts, I was anxious to see which of its 

 actions corresponded with the former and which with the latter. 

 They were quite tame at Guelt el Stel, aud I had abundant 

 opportunities of watching them. At that time the black of 

 the back was still edged with brown. Bill black ; mouth yel- 

 low ; eye dark brown ; legs, feet, and claws black ; soles of feet 

 rather lighter. Length of tongue | inch, arrow-shaped, with the 

 tip slit. Food small beetles, small caterpillars, &c. 



49. Cyanecula leucocyanea, Brehm. Blue-throated War- 

 bler, White-spotted Bluethroat. 



This Bluethroat, which was pretty common at Laghouat, seems 

 only to show itself on being frightened, when it seeks the cover 

 of rushes. It pi'efers young wheat and reedy places, and as a 

 rule does not perch on trees. 



There is but little of the Redstart in its habits. I frequently 

 saw the two species at the same time (though never consorting); 

 and a greater contrast it would be difficult to imagine. 



50. Erithacus rubecula (Linn.). Robin. 



When I arrived in February there were hundreds of Robins 

 m the Algiers poultry-market ; but whether the bird is any thing 

 more than a winter visitant I cannot say. 



51. Calamodus schcenob^nus (Linn.). Sedge Warbler. 

 Laghouat. 



52. Calamodus aquaticus (Lath.). Aquatic Warbler. 

 This Warbler is not included in Dr. Tristram's list; but I 



found it, together with the Sedge Warbler, in the small half- dry 

 marsh at Laghouat which I have so often had occasion to men-
