BIRDS OF TUNISIA 



nests and eggs of this Lark in the Algerian Sahara, we are indebted 

 for some interesting notes concerning its breeding habits. The nests 

 he found were generally placed at the foot of a desert shrub, often 

 Helianthemum Mr turn, and were carefully constructed of plant-stems 

 and grasses, lined with little wool and pieces of linen stuff, the whole 

 being surrounded by small stones. The eggs, of which two appear 

 to be the usual complement, although three are sometimes found, 

 vary considerably in tint, the ground-colour being at times cream- 

 colour, at others a pinkish-white, and occasionally bluish or greenish- 

 white ; the shell-spots are violet, and the surface-spots brick-brown. 

 Sometimes the entire surface of the egg has a clouded or marbled 

 appearance. The average measurements appear to be 21 x 15 mm.
