698 Messrs. Sclater and Mack-worth-Praed on [Ibis, 



c. Yellow-vented^ and with a scaly appearance owing to 

 white edging to the feathers of breast and back. 



P. dodsoni Sharpe. S, Somaliland and desert country of 

 British East Africa to Kilimanjaro region. P. spurius 

 Reicliw. from Gallaland and P. t. peasei Meariis from 

 Kitunga, B.E.A., are described as being intermediate 

 between this species and P. layardi. We cannot identify 

 these two forms. 



d. Yellow-vented and wattle-eyed. 



P. niyricans niyr'icaas (Vieill.). Cape Colony to Damara- 

 land, Transvaal, and Natal. 



P. nigricans harterti Zedlitz (J. f. O. 1916, p. 71). Benguela. 

 This form has a wattled eyelid, although not so distinct 

 as that in P. n. nigricans^ and undoubtedly belongs to 

 this group. 



P. xunthopygos xanthopygos (Hempr. & Ehr.). Sinai and 

 Palestine. 



P. xanthupygus reichenoivi Lorenz & Hellm. S. Arabia. 



P. capensis (Linn.). Cape Colony. This species has the 

 colour of the head absolutely uniform with the back, 

 and the whole underside is very much duskier than any 

 other form. It stands therefore rather by itself. 



Phyllastrephus strepitans rufescens. 



Phyllastreplivs rafescens Hartlaub, Orn. Centralb. 1882, 

 p. 91 : Lado district. 



[Butler coll.] 2 Rejaf Feb. L.E. 



We are unable to distinguish the various forms of 

 P. strepitans recognized by Zedlitz, except P. s. pauper from 

 Abyssinia, which is markedly more reddish. The others, 

 P. s. strepitans from Mombasa, P. s. sharpei from Dar-es- 

 Salaam, and P. capensis suahelicus from south German East 

 Africa, all seem very similar to our bird ; if it is distinct it 

 should be named as above.
