506 BIRDS OF SOUTH AFRICA. 
505. AMMOMANES ERYTHROCHLAMYS (Strickl.) 
Rufous-mantled Lark. 
The present species differs from the preceding in the pale ashy 
lining of the quills, the inner webs of the primaries inclining to 
isabelline. It also has not the greyish flanks of A. ferruginea. 
We have seen a number of specimens from Damara Land collected 
by Mr. Andersson, but they appear to be all in winter plumage. 
The only bird in summer plumage, that has come under our notice, 
was shot by Mr. T. Ayres in the Transvaal, in June, 1872. He 
writes :—“I shot the specimen sent, a female, amongst some rocks 
and stones in a low range of hills some three or four miles from 
Potchefstroom ; it had a peculiar knack of hiding itself by creeping 
over and about bits of rock.” 
The following is a description of a Damara specimen :— 
Adult male in winter plumage.—Above uniform pale fawn-colour, 
with indistinct shaft-stripes of dull rufous on some of the feathers 
of the head and back; wing-coverts pale fawn, like the back, but 
with pale yellowish buff margins to the feathers ; quills pale brown, 
broadly margined with fawn colour, the secondaries more broadly, 
the innermost being coloured like the wing-coverts and margined 
in the same manner with yellowish buff; tail dark brown, narrowly 
margined with fulyous fawn colour, occupying the entire outer web 
of the last tail-feathers, and running round the tip and up the margin 
of the inner web of this and the penultimate feather; the two centre 
feathers bleached fawn colour, paler than the back ; lores, feathers 
below and above the eye, forming an eyebrow, and cheeks white, 
the ear-coverts pale fawn colour like the back; under surface of 
body creamy white, washed with fawn colour on the sides of the 
body, the chest spotted with triangular markings of pale brown; 
thighs pale fawn; under tail-coverts creamy white; under wing- 
coverts buffy whitish, the greater series pale ashy brown, the outer 
plumes fawn coloured ; inner lining of wing also pale ashy brown, 
inclining to pale fawn colour at base of inner web. ‘Total length, 
6°5 inches ; culmen, 0°75; wing, 3°6; tail, 2°38; tarsus, 1-05. 
The summer dress is different from the winter, and is of much 
rarer occurrence in collections than the latter; indeed we have only 
seen one example, the one figured by Mr. Ayres (/.c.). It differs 
in the following particulars :—
