features I did not record in the ' Catalogue.' A young 

 female after the first moult, in winter plumage, is much 

 more isabelline on the under surface, and verges towards a 

 tawny shade on the lower flanks. 



The four eggs are bluish white with a few scattered spots 

 and short irregular lines of black, mostly at the larger end. 

 Axis - 6 inch, diam. 0*55. 



[Very common, generally seen in small parties of five or 

 six, even during the nesting-season. They may be obseved 

 drinking at the small springs on the kopjes at all hours of the 

 day. The nest is generally built on the top of a veldt bush ; 

 it is lined with the wool from the seeds of the Karoo bush.]

My remark (Cat. B. xii. p. 360) as to the spots on the 

 throat being a sign of the female bird goes for nothing; 

 in fact, there are more distinct spots in the male than in the 

 female. A young male is much more broadly and distinctly 

 streaked on the upper surface, and has the under surface more 

 isabelline, with dusky brown streaks on the chest and sides.
