also (with the exception of the Elgon specimen) such a very 

 pale gloss on the fore-neck. Only one of the females from the 

 Nairobi regions has a narrow white edge on some of the wing- 

 coverts; in all the others these feathers are black with red edges. 



The length of the wing and the tarsus of the different 

 specimens are: 



Wing, tarsus, 



d*cf 79, 84, 84 mm. 15—16 mm. Nairobi. 



99 73, 74, 76, 79 ram. 16-16.5 mm. „ 



9 81 mm. 16 mm. Elgon. 



Irides dark-brown; the blue rings around the eyes are 

 sometimes as much as 3 mm. wide (in most cases, however, 

 1.5 — 2 mm.); bill and legs dark lead-grey.

The male specimen of this race differs so greatly from the 

 preceding, that it cannot be placed under that race in spite of 

 the great individual differences existing between them. — 

 V. Someren (Journ. of the E. Afr. & Ug. Nat. Hist. Soc, vol. 

 6, 1918, p. 256) refers his Mombasa specimens to T. p. suahelica, 

 but as the distinctive features which characterise that race are 

 not found in my specimen I cannot refer it there. On comparing 

 my bird with the specimens in the Berlin Museum I came to 

 the conclusion that my specimen must be placed under plum- 

 heiceps, with which it agrees perfectly. 



The gloss on the head is considerably paler than that of 

 the preceding race and is entirely lacking on the neck and breast. 

 The breast is dark-grey, the belly whitish (with a pale light-grey 

 wash along the flanks), under tail-coverts entirely white (without 

 any brown or brownish red wash whatever). Lower wing-coverts 

 white, some with brownish red tips. Under tail-coverts white. 

 All the wing-coverts are brownish red, and the bird has not the 

 slightest trace of white, either on the wings or tail. The central 

 elongated rectrices extend 115 ram. beyond the 90 mm. long tail. 

 Wing, 75 mm. tarsus, 15 mm. 



Irides, bill and legs as in the preceding. Ring round eye 

 3 mm wide. 



It is rather noteworthy that a South- West African bird, 

 which is not hitherto known farther north than to Tanganjika 

 and the Niassa region, is found in Mombasa. There can hardly 

 in the present case be any question of a casual aberration.
