.18 BIRDS OF SOUTH AFRICA. 
only two, but Mr. Atmore affirms that he has taken from two to five 
eggs out of nests of this species. It occurs on the eastern frontier 
and about the Berg river. 
Le Vaillant states that the male sings for hours together in the 
twilight of morning and evening, and sometimes through the night. 
This we never noticed at Nel’s Poort, where it is very abundant, 
as it is throughout the Karroo. It will perch on the top of a high 
tree, utter its mellow piping whistle, and fly off again. We have 
sometimes heard it call while on the wing, as also has Mr. Atmore. 
Upper parts and breast pearly-grey ; belly white variegated by 
many brownish-blue lines; shoulders light grey; rump white. 
Larger wine-feathers black ; the tail dusky, tipped with white, and 
crossed by broad white bars, except upon the two middle feathers. 
Cere and legs red. Irides orange, according to Mr. Atmore dark- 
brown. Length, 24’’; wing, 13’’ 6’’’; tail, 12’’. The young bird 
of the first year is brown above, the secondaries being edged with 
rufous and white, upper tail-coverts pure white. Below it is white, 
the throat and chest being longitudinally striped with rufous brown ; 
breast, belly, vent, and thighs transversely barred with broadish 
rufous bars. é 
Mr. Ayres (Ibis, 1869, p. 219) gives the following details of the 
soft parts of an immature male. Inis yellow; bill black at tip, yellow 
at base; cere yellow; tarsi and feet red.

Only one specimen of this bird has as yet been known to occur 
within our limit. Mr. Gurney thus records the circumstance :—“ An 
adult male of this species was obtained by Mr. Andersson at Ele- 
phant’s Vley, on November 10th, 1859, and is preserved in the 
Norwich Museum. I know no other instance of this species 
occurring so far south ; and it is remarkable that it should have 
been obtained at the same spot, and within fifteen days of the same 
date as the specimen of Asturinula meridionalis. 
Adult male.—Above light bluish slate colour, the sides of the face 
and region of the eye a little darker ; lesser wing-coverts coloured 
like the back, the greater ones rather lighter and slightly freckled ex- 
ternally with white; primaries blackish, externally shaded with ashy 
grey, the secondaries pale greyish, freckled’ with white, the inner
