 but the colouring is darker above and the underside paler.

In this series there are birds with brown backs and others 

 with slaty-grey backs. This variation is not accounted for 

 by age or sex, according to our birds. Several subspecies 

 have been described by American ornithologists, descrip- 

 tions of which agree well with the examples before me, 

 but I doubt if there are even two distinct subspecies here. 

 One of our specimens has a wing-measurement of 98 ram. 

 and a tail of 90 mm. 



Tliese birds were nesting in April and May. The nest is 

 generally placed in a crevice in an old tree or rock, not high 

 up, and is constructed of rootlets, moss, and fibres. The 

 eggs (two in number) are dark olive-green or olive-green 

 with brownish mottlings. 



Localities. Mabira, Kyetema, Kasala, Mpumu, Jinja, and 

 Mubango, in Uganda.
