94 Mr. J. I. S. WLitaker on Tunisian Birds. 



mediate forms may occur. In the Florence Natural History 

 Museum, for instance, I have seen a specimen labelled S. 

 stapazina ad. ^ , from Genoa, with the narrow hlack throat- 

 band, but with dark scapulars, and with the inside of its 

 wings dark. As this specimen, however, also possesses a 

 peculiarly marked dark back, I think one would be justified 

 in looking upon it as abnormal, and possibly a hybrid. 

 Besides the opportunity afforded me, through the kindness 

 of Prof. Giglioli, of comparing my specimens with those in 

 the Florence Museum, 1 have also been able to examine those 

 in the Turati collection at Milan, now being put in order, 

 under the able supervision of Dr. Marfcorelli. 



7. Saxicola lugens. (B. M. Cat. B. v. p. 370.) 



I obtained specimens of the Pied Chat this year, both male 

 and female, at Ras-el-Aioun, to the west of Gafsa. This 

 species, however, seems to be rather rare in the Regency, 

 this being the ouly occasion on Avhich I met with it in 

 Tunisia, although I had previously found it in the Algerian 

 Sahara. It is a shy, retiring bird, evincing a partiality for 

 desolate spots, particularly where there are marl cliffs, in 

 which it no doubt finds suitable nesting-places. 



8. Pratincola rubetra. 



I found the Whinchat near Tunis and at Feriana. 



9. Pratincola rubicola. 



The Stonechat I also got at Feriana. 



10. Daulias luscinia. 



Common at Gafsa and further north. 



11. Sylvia cinerea. 



The Whitethroat I met with constantly. 



12. Sylvia curruca. 



The Lesser Whitethroat I also met with, although not so 

 often as the preceding species. 



13. Sylvia subalpina. (B. M. Cat. B. v. p. 27.) 



I obtained specimens of this Warbler in the pine-woods 

 north of Feriana, but it is not common in the Regency.
