B. h. Ulineata has the chin and throat white, B. h. jack- 

 soni Sharpe, on the contrary, greyish white. The edges of the 

 wing-coverts and wing-feathers are not always a darker sulphur 

 yellow in B. b. hilineata than in B. b. jacksoni but frequently 

 vice versa. My specimens of the former have considerably paler 

 sulphur-yellow edges than the latter. The richer or paler sulphur- 

 yellow colour on the edges of the wing-coverts and wing feathers 

 varies with the seasons and does not seem to me to be a deci- 

 sive character of any systematic value. 



Reichenow (Orn. Monatsber., 1915, p. 91) has further 

 described another form from Tanganika, which is said to be 

 very similar to Jcandti but has the rump lighter citron-yellow: 

 urungensis. 



The various measurements of my specimens, however 

 somewhat higher than those given by R e i c h e n o w for Bar- 

 batula b. bilineata. 



Wing, tarsus, culmen, tail, 



55 mm. 16 mm. 14 mm. 28 mm. cT 23. 5 



58 mm. 16 mm. 14 mm. 30 mm. cT 5. 6. 



Irides dark brown; bill black; legs dark lead-grey.

1 Q ad. 10. 4. Nairobi. 



Only a single specimen was procured of this bird, which 

 is closely related to the preceding. It is grey on the throat and 

 the grey colour of the fore-neck is darker than in B. h. bilineata. 

 Further, the yellowish green edges of the wing-coverts and wing- 

 feathers in this subspecies run more into yellow and the flanks 

 have a darker brownish grey. 



Wing, tarsus, culmen, tail, 



54 mm. 16 mm. 14 mm. 32 mm. 



The measurements, on the whole, agree with those of the 

 preceding, and therefore they cannot thus be a conclusive factor 

 in fixing these two birds.

2 (5(5 ad. 29. 4. Mombasa. 



This race was met with on my excursions in the Mombasa 

 coastal regions. It was found on the open tracks of country 

 where only a few solitary trees and bushes stood at longer or 

 shorter distance from each other. It sat still for a long time 

 on some tree -top, from where might be heard the few shrill 

 notes of its song.
