specimens, but that also—unless the race is one so distinct 
as to preclude any possibility of confusion—he should have 
some ideas as to its limits. 
Francolinus sephena zambesiz, subsp. nov.

Francolinus albogularis gambagez, subsp. nov. 
Appears to differ constantly from F. a. albogularis Gray, 
from Gambia, by the colour of its breast and crop, the 
feathers of which are, in both sexes, strongly edged with 
rufous, not plain ochreous as in the typical race. The sides 
of the neck are also more strongly rufescent. ,

Francolinus natalensis neavei, subsp. nov. 
The male of this race differs from that of F. a natalensis 
Smith, in the bolder but less numerous markings of the 
underside, and these are disposed more longitudinally on the 
feathers. The tone of the upperside, especially of the crown, 
is somewhat greyer also. 
The female is even more distinct from that of the typical 
race, as it has the same sparseness of markings as the male, 
but the markings are brownish, and there is a brownish-rufous 
tinge over the underside which is still more pronounced in 
the young. The race thus shows a transition stage on the
