Chrysococcyx smaragdineus. (Emerald Cuckoo.) 

 This bird is rare about Grabamstown, although it becomes 

 commoner towards the Great Kei River. The Woodwards 

 are the only previous observers who have noticed the niditica- 

 tion of this species. Two birds were shot in October and 

 December containing shelled eggs, one white and the other 

 white speckled with purple (y'lde Sclater, " Birds," Fauna of 

 S. A. vol. iii. p. 18Gj. 



A young bird with " quill " feathering was taken from a 

 nest of the Cape Sparrow [Passer arcaatus) on Keevey's 

 Farm, at Koonap. Koonap River is part of the dividing line 

 between the Albany and Beaufort Districts of Cape Colony. 

 It only lived for about a fortnight, but developed very quickly, 

 as it had the yellow underparts and bright metallic coloration 

 of the upperparts before it died. 



Chrysococcyx klaasi. (Klaas' Cuckoo.) 



The egg of this species varies in shape and colour, but not, 

 so far as we are aware at present, so much as that of the 

 Didric {C. cupreus). On November 9th, 1902, Mr. Pym 

 took a clutch of seven eggs — six of the Malachite Kingfisher 

 [Corythornis cyanostlgma) and one larger and more elongated 

 egg (vide fig. ill., Plate III.), which was ascribed to Klaas' 

 Cuckoo [vide Ivy, 'Ibis,' 1901, p. 28). This egg was beauti- 

 fully transparent ; the yolk showed through the shell and 

 gave a pinkish tint to the egg. On blowing the eggs the 

 yolk of the Cuckoo's was found to be of a much deeper shade 

 of orange than that of the Kingfisher's. In Deceinhnr l^i95
