CAaPRIMULGUS RUFIGENA, Smith. Rufous-cheeked Goat-

Four specimens from the rocky bushy ranges near Pot- 
chefstroom. 
[The following are particulars of the four specimens above 
mentioned :— 
No. 1. Male, adult, shot 16th September. A white spot 
on the inner web of the first primary, and a similar spot ex- 
tending to both webs of the three next primaries, the shaft 
of the first and second being black where it passes the spot, 
and of the third and fourth white ; the two external pairs of 
rectrices tipped with white very conspicuously. 
No. 2. Male, immature, shot 20th February. Somewhat 
resembling the specimen described in ‘The Ibis’ for 1877, 
p. 342, but apparently a younger bird; the spot on the three 
first primaries white, tinged with buff, and on the fourth pure 
rich buff, confined in all four to the inner web, but a small 
distinct buff spot on the outer web of the fourth; the shafts 
of all the primaries black ; the tips of the two outer pairs of 
rectrices buffy white. 
No.3. Male,immature, shot 16th February, but apparently 
more advanced than the preceding specimen ; the spots on the 
primaries as in No. 1, but the white tinged with buff, especially 
on the fourth, and with all the shafts black; one new adult 
rectrice of the outermost pair as in No. 1, the other three 
apparently belonging to the immature plumage, and tinged 
with buff, though whiter than in No. 2. In the adult male 
plumage the portion of the external rectrice above the white tip 
is blacker and less barred with brown than in the young 
bird. 
No. 4. Sex uncertain, but probably a female, shot 16th Feb-
