CHAEADEIIDa; 55QIALITIS 371 



South African Museum an example of this species, with a well 

 formed egg inside, shot at the Salt Pan, near Port Elizabeth, on 

 August 23, 1902. Mr. J. G. Brown informs me that this bird is an 

 irregular migrant to Port Elizabeth, arriving about April and depart- 

 ing in October, and that he has only seen it on the edge of the water 

 of the Salt Pans, more rarely on the sea beach. Except for these 

 two instances, it has never before been noticed from South Africa. 



Ch. rufocinctus, Eeichw. (" Wiss. Ergeb. Deutsch. Teefsee- 

 Exped, VII," p. 352, pi. xxiii.), obtained at Great Pish Bay in 

 Southern Angola by the Valdivia Expedition, appears to be closely 

 allied, if not identical with this species.
