chin, and top of throat, jet-black, surrounded by a pale-yellow 

 edging ; a black halfmoon-shaped mark at the back of the 

 head, which is slightly crested. The whole of the body 

 plumage in the live bird is glossed with a beautiful pink 

 lustre, which fades after death ; each plume on being With- 

 draw [i shows a delicate ferruginous and very lax web 

 throughout two-thirds of its basal portion. Length, 20"; 

 wing, 14"; tail, 8". 



The Vaal Knorhaan is common on the Karroo, about Beaufort West 

 and Zoetendals Vley. It is usually found in pairs, and prefers running 

 among the scanty herbage, and trusting to its dusky plumage to effect 

 its escape, to taking flight. If it fancies itself unobserved, it will 

 suddenly squat, and unless the spot is correctly marked, so great is 

 its similarity to the soil and stones among which it is found, that it is 

 next to impossible to detect it. It is so well aware of this, that it will 

 remain immoveable till the sportsman walks direct towards it, on 

 which it instantly takes flight ; but if it is approached in a series of 

 concentric circles, it remains until the sportsman is within a few paces. 



It feeds on seeds, insects, and smaH reptiles, constructs no nest, 

 but deposits its two eggs in a depression of the soil in the open veldt. 

 The eggs vary much in colour some are olive, some light-brown, and 

 others rich nankin. All are, however, more or less spotted and 

 blotched with brown and indistinct purple. Axis, 2" 8'" ; diameter, 

 1" 10"'.

 of front of neck, breast, belly, and vent, blue ; forehead, eye-

This beautiful bird is locally distributed. I have received it from 

 Hiversdale, and from the neighbourhood of Hanover, and have been 

 told that it is plentiful on the Eastern frontier in certain favoured 

 spots.
