EINAR LÖNNBERG, BIRDS FROM BRIT. E. AFRICA. 13 



broad band between the shoulders across the otheiwise white 

 back. In one of the males this band is 35 mm., but in 

 another male the greater part of the back, 62 mm., is purely 

 black. 



The length of the wing is in the males 98 — 100 mm., in 

 the females 94,5 — 99 mm.

The white spöts on the head and the back as well as 

 the white markings on the wings are much larger and better 

 developed in the latter of the females than in the first, 

 although both are from the same locality. This difference 

 appears to depend on age, the bird with the larger white 

 markings being the older.

The first of these has rather dull colours and obsolete 

 markings. The second specimen is more olivaceous on the 

 back. Both are rather darker than typical specimens from 

 South Africa. The first mentioned specimen is rather spar- 

 sely spotted, not barred, with whitish on the chest and 

 upper breast. In this respect it thus approaches the sub- 

 species schoensis, but in neither of the present specimens do 

 the ocular and målar black bands unite, nor do the latter 

 join inter se below the white throat. They can for that 

 reason not be referred to Th. n. schoensis, but form very 

 interesting connecting links between the typical form and 

 the subspecies mentioned. The specimens which I collected 

 at Nairobi, a locality, which is not very distant from this 

 one, I could refer without hesitation to schoensis. Specimens 

 from Kilimanjaro on the other hand are Th. namaquus nama- 

 quus with broadly separated black bands. These facts show 

 where both forms meet and these intermediate specimens 

 elucidate this still more plainly.
