Birds of Southern Cameroon. 527 



I bc4ieve now that the peculiar noise of the different species 

 of Smithornis is made with the voice, as Mr. Swynnertou 

 thought (' Ibis,' 19C8, p. 92) and not with the wings. It is a 

 call to attract the mate, and probablj^ made by the male 

 alone. It is made only while the bird is taking short 

 circular ilights^ and at the same time displaying the white 

 feathers of its back.

No nest of the smaller forest ]\Ibamezok has been recorded 

 before. One (brought ia with tlie sitting female bird, 

 No. 4407) was like the nests of other species of the genus, 

 and was made of materials obtaineil in the forest. The two 

 fresh eggs (answering to the two empty sheaths found in 

 the bird's ovary) were pure Avhite with glossy and rather thin 

 shells, and measure 23 x 15'5 and 22 x IG mm.

The date o£ the original description by Alexander Avas 

 Jan. 1903 (not 1902); l)ut still his name has the pre- 

 cedence over that given by Reicheuow and [)ublished in 

 March 1903. 



Another nest and eggs have been fouud and brought to 

 me with the bird still alive, caught at evening in the nest. 

 The fabric was made of fine black fibres and dried leaves, 

 sucii as would be obtained in the forest, not on cleared hind. 

 The two pure white eggs measure respectively 24"5 x 17 and 

 22 X 16*5 mm.

The male is exactly like the bird obtained at Efulen in 

 1902. The adult female has the u[)per parts like the male, 

 though with less lustre, and the Mdiite spots on the wing-
