2584 The Zoologist — May, 1871. 



A. arboreus, Bechsl. — This bird was seen by me coulinually 

 from after the month of March. 



Budytes jiava, Bp. — Seen, for the first time, at the end of March, 

 on the lal<es between Batna and Constantine. The other neaily- 

 allied forms mentioned by Loche 1 could never calch sight of, in 

 spite of very careful search for them. 



Pallenura sulphurea, Bp. — To be met with throughout the 

 whole winter about mountain-streams, though, generally speaking, 

 not numerous. 



Molacilla alba, L. — Might be found everywhere during the whole 

 winter: we did not succeed, however, in getting a sight of the 

 local variety,* M. algira of De Selys. 



Cinclus aquaticws, Bechst. — We saw only a single individual, , 

 in December, by a mountain-stream between Ghelma and 

 Mahuna. 



Ixos obscurns, Teram. — Found throughout Algeria, in the 

 thickets of the hill-country, especially in those districts bordering 

 on the sea: round about Batna we did not see one of these birds, 

 neither did we in the desert. Throughout the whole season these 

 birds kept in flocks. The males sang continually. 



Turdus viscivorua, L. — We met with these birds in many spots 

 in the hill-country, especially near Batna, in Bonarif, in the Aures, 

 but they were nowhere numerous. 



T. merula, L. — Winters in large numbers in the oases, yet 

 rarely to be seen in the hill-couniry. 



Sphenurafulca (Maluius nuiuidicus, /^'dvj///. Crateropus fulviis, 

 Bp.) — This species is found everywhere throughout the desert, on 

 sand-hills which are thickly covered with bushes, in tamarind 

 woods, and sometimes on the borders of the oases. These birds 

 keep in flocks consisting of about twenty pairs ; continually 

 changing their places, liiey fly down into a thick bush, and run off 

 with great agility one after another, into another bush : as tliey 

 shriek incessantly, however, one may easily find out where they 

 are. They differ somewhat in their colouring from the Egyptian 

 Sphenura Acaciae of Licht. 



Drymotca saharcc (Malurus Sahara;, Loche). — Common in the 

 desert, in bushy sand-hills. They keep for the most part in flocks 

 consisting of a few pairs : they run along quickly on the sand and 

 hide themselves in thick shrubs : the males hop with uplifted tails 

 and sing beautifully.
