JV/rtls of Soiitlierii Catncroon. 53D 



iVests with eg^s or young- were fouiul in the nioiit'.is of 

 August, September, and October. 



Nine eggs have been collected. The smallest of these, 

 No. 287 (tig. 2 in the Plate), measures 22 x 16 mm. ; No. 289 

 (fig. 1) measures 27x18 mm. ; another is 26*5 mm. long. 

 These measurements give the extremes. 



[Eggs of this species vary in shape from a long rather 

 pointed oval to a wide regular oval; they have little or no 

 gloss. The ground-colour is ])ale blue, pale greenish-blue, or 

 in one instance creamy-buff. In some examples the markings 

 are more or less regularly distributed all over the shell, in 

 others they are mostly confined to the larger end, where they 

 form a dense cap or l)road zone. Tlie surface-markings are 

 reddish-brown or yellow-umber and the shell-markitigs are 

 bluish-grey or lavender-grey. — O. G.]

The varying shades of black, grey, and white on the backs 

 of females of this species has caused much perplexity. 

 Sharpe recognised (doubtfully) two species among my bii'ds, 

 and Neumann thought there were two species found in 

 Cameroon, in which the males were alike, only the females 

 diifering. My large series of specimens, including those 

 listed above, together with those in the British JNluseum 

 from former collections, contains many adult males, but 

 all with glossy black backs and wings and jaire white 

 rumps; while the females differ in all degrees, from those 

 with grey backs and wings and light grey rumps, to one 

 almost like the male on the back and rump. It is not 

 unreasonable to suppose the last was an old female, and 

 that as females advance in age they become more bke the 

 males in plumage.
