As these birds are subject to individual variation in a rather high degree, I suppose, 

 that the specimens in question have to be regarded as individual aberrations of Irriao) 

 jack.soni, although perhaps the birds of Kenia may have less white than those in other 

 places. The niale is rather large, but the females not beyond the iivcrage tor /. jachsoni. 



Specimens shot in a forest near Escarpment station had the normal extension of the 

 white on the hcad. 



The length of the wing of a male from this place is 143 mm, and the culmen 45 ni m. 

 There is thus hardly any difference from the specimens of the Kenia forest. 



A just fledged young shot at Escarpment station has the bill black and only 25 mm. 

 Head above blackish with a slight bronzy green gloss, back similar with more green gloss. 

 Wing and tail have exactly the same gloss as the corresponding parts of the adult. Fore- 

 head and throat with hoary whitish tips to the feathers. Under parts brownish black 

 without any gloss at all. This specimen was obtained 8th of Jan. and belonged probably 

 to a brood from the »small rains». 



The hitherto known distribution of Jackson's Wood Hopoe extends in the west to 

 f ndekaru, Ituri forest, Fort Mbeni, Ruwenzori, and Mpanga forest east of it, Lake Kiwu, 

 forests west of Tanganjika etc. It is thus widely spread in the Central African forest region 

 and the forests at Meru borna form no doubt the northeastern limit for this as for several 

 other forest birds. 



Rhinopomastus minor somalicus Erl. 



Eel., Journ. of Ornith. 1905. p. 461. 



In the thornbush north of Guaso Nyiri especially below Chanler Falls this species 

 was seen almost every day but as a rule only single specimens. It was rather shy, and it 

 was difficult to come within range of it with a small specimen-gun. The bill of some spe- 

 cimens looked decidely orange red, while that of others was yellow. 



A specimen was also procured on the acacia-steppe between Lekiundu and Luazo- 

 mela river nearer the latter 20 /.3. Length of wing 91 — 93 mm.

A female specimen of the common Goatsucker was shot on the acacia-steppe at Le- 

 kiundu river 20 /.3 1911. It perched on a branch of an acacia.

A male specimen from Njoro 27 /2 has the length of wing 136 mm. Another speci- 

 men shot in a thornbush patch on the acacia-steppe just south of Guaso Nyiri at Lekiundu 

 river is a little paler rufous but otherwise similar and undoubtedlv of the same race. 

 These specimens were f lushed from the ground.
