135 [Vol. xli. 



Distr. Southern part of Cape Province from Swellendam 

 east to Natal, also recorded from the Lydenburg district of 

 the Transvaal. 



It is difficult to believe that Pternistes castaneiventer 

 Gunning & Roberts (Ann. Transv. Mus. iii. p. 110, 1911 : 

 Fort Beaufort distr., Cape Prov.) can be anything but a 

 young example of this species. 



Pternistes afkr humboldti. 



Francolinus humholdti Peters, Monatsber. Akad. Berlin, 

 1854, p. 134 : Tete. 



Resembling P. a. krehsi, but the lower breast and belly 

 in adult black, and only striped with white on the flanks. 



Distr. The Zambesi and Loangwa valleys, Mozambique, 

 and the southern part of Tanganyika Territory. 



Mr. David Bannerman proposed to separate as a distinct 

 subspecies the race of Cyanomitra obscura inhabiting the 

 mainland of West Africa. 



It had already been pointed out by Ogilvie-Grant (Trans. 

 Zool. Soc. xix. 1910, p. 321) that C. obscura obscura from 

 Fernando Po, the type-locality, was distinct from the Con- 

 tinental bird, but Ogilvie-Grrant united the latter with the 

 Abyssinian race C. o. ragazzii Salvad, a course with which 

 Mr. Bannerman could not agree. This left the West- A.fncan 

 race without a name, and Mr. Bannerman proposed to call 

 it :— 



Cyanomitra obscura guineensis, eubsp. no v. 



Adult male and female. Distinguished from C. o. obscura 

 by having the underparts duskier (not p:ile greenish-white, 

 as in Fernando Po birds), by the base of the lower mandible 

 being darker horn-colour and less white, and by its smaller 

 size : the v\ing of 71 adult specimens measured 52-65 mm., 

 average 59 mm., against 22 adult specimens from Fernando 

 Po 58-68 mm., average 64 mm. 



C. o. ragazzii, the Abyssinian form, difEers from the new- 

 race in having the upper parts brighter green and the under 

 parts darker, strongly washed with yellowish-olive
