of the pale bill therefore falls to the ground, and the true 

 features of P. nustralis seem to be its more ashy upper 

 surface, and the very clear fawn-coloiir on the under surface, 

 this tint pervading the flanks. The eyebrow is very broad 

 and distinct. 



P. ussheri (Sharpe) is Professor Reichenow's next species. 

 Hab. Gold Coast. 



This he separates from P. australis on account of its grey 

 fore-neck and sides of body, the under tail-coverts being 

 greyish also. This seems to be a well-marked form. 



Then follow three races in which the flanks, fore-neck, and 

 under tail-coverts are fawn-coloured, marked with brownish 

 or yellowish brown. 



P. congener. — Hab. Nyasaland and the Zambesi. This 

 is said by Professor Reichenow to be nearly allied to 

 P. ussheri, but to differ in its black bill [not a character], 

 whiter under surface, and browner upper surface. The 

 sides of the body and under tail-coverts are washed with 

 buffy greyish brown, paler on the fore-neck. 



These characters may be admitted, and Dr. Reichenow is 

 correct in believing that Sir John Kirk's Tete specimens 

 belong to his P. congener. I named them P. minor in 1901 

 ('Ibis,* 1901, p. 46). He is, however, mistaken in con- 

 sidering General Manning's example from Karonga, which 

 I united with T. emini (/. c), to be the same as his P. congener. 

 The Karonga bird is much darker than the Tete specimens, 

 and has a distinct grey wash over the centre of the breast 

 and abdomen, instead of being pure white, as in P. congener. 

 The back and crown are dark rufous brown. In P. congener 

 the lower surface is very pale, and there is scarcely any 

 greyish shade on the fore-neck. 



P. floater is the Camaroon form of P. congener, but is 

 distinctly a darker bird, especially on the cheeks and sides of 

 the body. 



P. minor. — The specimens from Tete, which Capt. Shelley 

 and I thought must belong to Prof. Reichenow's P. minor.
