is common on those open heaths, Its favourite resort. The 

 egg, which is remarkable for its small size, is thus, together 

 with its colour, most admirably fitted for the deception which 

 it is intended to practise. Though very similar in some in- 

 stances to those of the Skylark, there is a character about it 

 peculiar to itself, by which it may be readily known ; its shape 

 is more oval ; it is, also, in most instances, marked with mi- 

 nute black dots. To Mr. Blackwall, I am indebted for several 

 specimens, from which the above figures are selected. They 

 are rarely so dark as Fig. 1 ; and usually rather more so than 

 Fig. 2.
