96 Mr. J. I. S. Whitaker on Tunisian Birds. 



west of Gafsa, and there but sparingly. In the Algerian 

 Sahara, however, and within a few miles of Biskra, I found 

 it more plentiful, and my friends who visited the country 

 south of the Chott Djerid also met with it constantly. It 

 is a shy, timid little bird, and on the approach of danger 

 hides in the middle of some scrub bush, from which it is not 

 easily dislodged. I generally found it in pairs, and, judging 

 from the condition of specimens obtained in the early part 

 of April, it was then breeding. 



25. Parus ultramarinus, Bp. 

 Parus teneriff(B. (B. M. Cat. B. viii. p. 14.) 

 This Tit was plentiful in many places, and I was some- 

 what surprised to find it as far south as Gafsa. P. ledouci 

 I did not find; I believe it occurs only in the more northern 

 and wooded parts of the Kegency. 



2G. Troglodytes parvulus. 



I found the Common Wren near Tunis. 



27. Motacilla flava. 



Common in many places, and generally in flocks. 



28. Motacilla viridis. 



Also common, but generally in pairs, or threes and fours. 



29. Anthus pratensis. 



Common both in the north and south. 



30. Anthus trivialis. 



Also common in many places. 



31. Anthus campestris. 



I obtained specimens at Gafsa, and further north. 



32. Oriolus galbula. 



A common spring migrant. 



33. Lanius algeriensis. 



I have specimens of this Shrike from Tunis, where I have 

 shot the bird within a short walk of that town. It is common 

 throughout the north of the Regency, but I have never met 

 with it in the south, w^here it seems to be entirely replaced 

 by L. dealbatus. Its habitat proper is no doubt the Tell
