Type, adult d, in breeding plumage, taken at Wakkerstroom, on 25th 
October, 1909. Also two similar specimens from the same place. “Iris yellow- 
ish brown; maxilla brown, mandible pater; tarsi and feet dark flesh colour. 
Length in the flesh 158 mm.” Wing 60, tail 63, tarsus 20, culmen 13. 
Dryodromas fulvicapilla silberbauer subsp. nov. 
Differs from the typical D. fulvicapilla from the eastern districts of the • 
Cape Province in being altogether darker coloured, the crown only slightly 
more inclined to reddish than the back (which is also darker than in typical 
specimens), the throat and belly less white, on the former hardly noticeably 
whitish. 
Type, adult $ , taken at the foot of the Groot Drakenstein Mountains, on 
the estate of C. C. Silberbauer, Esquire, “Lormarins,” in the Paaii District, 
in September, 1917. Also another similar specimen taken at the same time. 
“ Iris dull tan yellow; bill flesh coloured, culmen and tip brown; tarsi and feet 
flesh coloured. Length in the flesh 116 mm.” Wing 46, tail 42, tarsus 17-5, 
culmen 10-5. 
Note. Females of the typical birds are paler than males, so that possibly 
the males of this more western subspecies are still darker than the females 
secured. 
Euplectes capensis macrorhynchus subsp. nov. 
Differs from the typical E. capensis from Cape Town and neighbouring 
districts in having an even larger, or in fact, an enormously powerful, bill, 
the culmen in the type measuring 21 mm. in an adult male in full breeding 
plumage, as against only 18-19 mm. This measurement alone, however, does 
not give an impression of the increase in size, for the breadth and depth are 
still greater in proportion. In an immature $ taken about the same time and 
place, the culmen is 20-5 mm. Type, adult $ in breeding plumage, taken at 
Klaver on the Olifants River, Cape Province, October, 1917. Also an im- 
mature d* 
Careful measurements of the long series of specimens shows an extra- 
ordinary constancy in the length of the culmen amongst specimens from given 
ranges, and there is shown to be a graded (though not intergrading) increase 
in size, of which the following will give a clear idea.

Mirafra apiata adendorffi subsp. nov. 
Differs from the typical Mirafra apiata (Vieillot) in its larger size, less 
rufous outer and inner margins to the primaries, and more rufous head and 
back. There is only a faint trace of black markings on the feathers of the nape 
and head generally, while on the back the rufous is much more conspicuous, 
perhaps the effect of wear, but nevertheless much more extended than in 
typical birds.
