Birds of Southern Kamerun. 
halfway from the Ja to the coast, on my way to England 
last April, a pair of Psalidoprocne nitens (known by their 
square tails) entered and perched on a paper ornament 
hanging from the ceiling. Mr. Hope, who lives in the 
house, said that they had done this often during several days, 
and had brought mud and tried to stick it to the ceiling, 
which is covered with cloth, but the mud would not stick. 
This is all the more remarkable, since the usual breeding- 
place of the species is in holes dug in banks, and not in mud 
nests of tlieir own building. 
1000. Fraseria ocreata. 
Sharpe, Ibis, 1908, p. 328. 
No. 2613. cT ad. Akok, between Efulen and Kribi, July 
10, 1907. 
In my brief note on this bird (/. c.) I said “ I have been 
told it has a song.” I had been correctly informed. When 
on my collecting-trip to Akok, between Efulen and the 
coast, in July, one day about noon a bird-song of rare 
sweetness and variety was heard in the tree-tops over the 
camp. It was a surprising performance, and both I and 
my boys were soon looking to see the bird from which it 
came. We found it at length and followed it from tree 
to tree, as it went, continually singing in an excited manner. 
The song was made up of a great variety of notes, some 
imitating the call-notes of other birds (such as Dicrurus 
atripennis and Bias musicus\ Mingled in its song were also 
the buzzing call-notes that I already knew well as those of 
Fraseria ocreata. Soon another bird of the same kind, 
singing in the same way, was heard near by. It was shot, 
and its skin is No. 2613. But I had already seen the first 
one plainly enough to be sure that it belonged to this 
species. 
This song struck me as resembling that of Lanius mac - 
kinnoni. It is characteristic of a Shrike to sing only 
occasionally, and then with surprising sweetness. Reichenow 
puts this genus among the Flycatchers.
