which is a rare bird in Zululand, as well as the very pretty 

 " Blue birds/^ as we call the Glossy Thrush [Pholidauges 

 verremixi). We found here the stick-nest of the Hatadah 

 Ibis in a tree overhanging a small stream. It contained 

 two large eggs, green smeared and blotched with brown, 

 measuring 2\ inches long. The Common Oxpeckcr was 

 nesting in the holes of trees ; the eggs are white. The rarer 

 species {Biqjhaga africana) we found only at the Umbega- 

 musa, between the Black and White Umfolosi rivers. We 

 got a nest of Turdus libonyanus near the river in one of the 

 shrubs ; it had four eggs, white blotched with red. There 

 were a few of the Green-and-Yellow Parrot nesting in holes 

 in dead trees in the open; we found one egg, pure white 

 and nearly round. After a short stay here we returned to 

 Eshowe. 



XX. — On the Grey Shrikes of Tunisia. 

 By Joseph I. S. Whitaker, F.Z.S. 



In my Notes on Tunisian Birds in 'The Ibis' for 1896 

 (p. 94) I referred to Lanius fallax a specimen of Grey 

 Shrike which I had obtained the previous year in the South 

 of the Regency, and which differed entirely from the ordinary 

 form of Grey Shrike found in that country. In the course 

 of a journey I made in the spring of the present year (1897), 

 when travelling in a part of Central Tunisia not previously 

 visited by me, I met with Grey Shrikes exactly similar in 

 plumage-colouring and marking to the above-mentioned 

 specimen referred by me to L. fallax. In the same district 

 I also met with other Shrikes, some of which resembled 

 more closely L. algeriensis, and some rather approximating 

 to L. elegans. I found these birds in the district between 

 Kairouan and Djilma, which immediately adjoins the 

 southern spurs of the Eastern Atlas Mountains and lies 

 between them and the more desert country further south. 

 The character of the country in this district, as might be 

 expected, partakes both of that of the Tell, or region north
