Little-known Birds from near Beira. 37 



known as S. Jencomekrna, and might be retained as a 

 subspecies under tbe above name. 



4. Grey with white shoulders, but the mantle and under- 



parts much darker than the head. Scarce. 



5. Grey with grey shoulders, the shoulders paler than the 



rest of plumage. Common. 



6. Grey with white shoulders. Common. 



I consider that the amount of white on the underparts, 

 like that on the tail, to be purely an individual variation, 

 some birds having more, some less, when otherwise in the 

 same plumage. 



The females also vary slightly in depth of colouring, some 

 being darker in colour, some much lighter.

 the trunk, with smooth bark, and with no branches for at 

 least 25 ft. 



On climbing a tree close alongside a good view of the 

 interior of the nest could be obtained from a higher level, 

 and it was found to be empty and not completed. 



On examinino- the nest ao;ain on Oct. 17tli two eogs were 

 seen, but it was not until a quantity of leaves had been 

 removed from inside the nest that the eggs were discovered, 

 they being entirely covered up. On approaching the nest 

 I could see that it was occupied, and moved cautiously to try 

 to get a shot at the parent bird. Just as I reached the tree 

 the bird left the nest, when I manaoed to l)ao; it. The male
