 and black ; tail black, with greenish reflections, tipped with

Le Vaillant has evidently, in his description of " Le Coucal Hou- 

 hou" confounded the Egyptian species (C. ^Egyptius) with this one ; 

 his figure, indeed, better accords with our bird man with the Egyptian. 



I have received but two specimens of *' BurchelTs lark-heeled 

 cuckoo." One was shot in " Grootevadersbosch," near Caledon, by 

 the Hon'ble T. H. Vigne ; the other near Swellendam, by Mr. Cairn- 

 cross. 



Le Vaillant states that he first met with this species near the Gam- 

 toos Hiver, and that it makes its nest in holes of trees, laying four 

 eggs, of a reddish- white colour.

Le Vaillant states he discovered this spec'ies in Kaffraria, and

 it is a manufactured species.
