They are not very shy (Bohni, according to Re ichenow, 

 considers them to be very shy) and in their behavoii they recall 

 our own Turdus pilaris in many respects. 



The plumage of the adult birds agree very well with Rei- 

 chenow's description. Still, one cf specimen has a brownish 

 patch on the fore -neck, another has such a one on the right 

 side of the body. The lower surface is in general a uniform 

 greyish brown. In one 9 specimen there is, however, a sug- 

 gestion of dark shaft- spots on the feathers, which is otherwise 

 a characteristic of the following form. 



The young birds are all predominantly brownish above, 

 thus recalling melanops, and the feathers have not the light fringes 

 found in the adults, which give them a highly aberrant appear- 

 ance. The throat is more whitish (in the adults grey). Breast 

 and belly are mainly grey; flanks, crissum and tibia brownish 

 yellow (in the adults grey — faint greyish brown).

1 Q ad. 22. 4. Lake Naiwasba. 



This recently described form from Naiwasha differs rather 

 distinctly from sharpei in the characters mentioned by v. 

 Someren, viz. "darker grey on the upper and lower surface, 

 and the feathers of the breast and abdomen have dark centres". 

 The throat is whitish grey with dark shaft-spots to the tips of 

 the feathers. 



v. Someren gives the wing to 115 — 1 30 mm., and al- 

 though the specimen before me does not reach the minimum, 

 but agrees in other respects with the above description and also 

 originates from the "terra typica", there is no doubt that it 

 should be referred to this form. The specimen is in moult. 

 Wing 110 mm.; culmen 21 mm.; tarsus 34 ram. 



Irides, bill and legs as in the preceding.
