the discovery of the adult bird before giving a name to it. 

 The specimen now in the Tring Museum looks much like a 

 very deeply coloured and small example of a young European 

 Goshawk. 



Dr. Ernst Hartert gave a short account of his journey 

 from Touggourt to Ghardaia, his sojourn in the Mzab- 

 country, and visit to Djelfa and the '^ Hauts Plateaux^' of 

 Central Algeria. He exhibited series of eggs of the various 

 Alaudidfe breeding in these districts, and made the following 

 remarks : —

" The chief breeding-season is undoubtedly the second 

 half of April. The nest is usually placed under small 

 desert-bushes, nearly always on the east or south-east side^ 

 exceptionally by the side of a stone. The clutches consist 

 of two or three eggs. These are remarkable for their 

 elongate shape^ one end being more pointed than the other. 

 The colour is vai'iable, but eggs which are finely spotted all 

 over are the rule ; stone-grey ones occur, while in some 

 a slight greenish tinge is sometimes apparent. The shell is 

 rather harder than that of eggs of Ammomanes. The eggs 

 are thus distinguished from those of Ammomanes deserti 

 algeriensis by their smaller size, more elongated shape, 

 and more frequent fine spotting. The thicker shell results 

 in heavier weight in comparison, so that an e^^ of the 

 Horned Lark of smaller dimensions will weigh as much as 

 a larger egg of Ammomanes d. algeriensis. Single eggs and 

 even single clutches are, however, not always separable with 

 absolute certainty.

 Lark. 



" Eggs may be found from the end of March to the 

 middle of May, but chiefly in April. The nests are similarly 

 placed and similar to those of Eremopkila, being in most cases 

 surrounded by small stones. The eggs are, as a rule, much
