sides of the neck does not extend round the neck, showing 

 that the rufous collar is not an invariable characteristic of this 

 species.

I have not seen the male of this species in full plumage, and 

 must therefore refer to the excellent figure given by Mr. Harting; 

 but I have examined three specimens in winter dress from Da- 

 maralaud, collected by the late Mr. Audersson. 



A male, shot at Otjimbinque on the 15th of December 1864, 

 agrees exactly in coloration with the Australian specimen of 

 Ch. asiaticus in winter plumage ; on the jugulum there are still 

 some hidden rufous feathers, which are the remains of the 

 summer plumage. 



Two females from the same locality are very similar. In one, 

 shot in Febi'uary, the brown feathers on the upper parts are de- 

 cidedly pale-margined, forming a collar round the nape ; the 

 front, eye-stripe, sides of the head, the chin and throat are buff- 

 coloured. This specimen agrees very closely with the female of 

 Ch. asiaticus from Saigon. 



It is therefore not always easy, at least in the immature and 

 winter plumages, to distinguish Ch. asiaticus and damarensis by 

 the plumage only ; but the measurements will invariably show the 

 difference, as will be seen by the following Table (in French mea- 

 surements, vide ' Vogel Ostafrika's ').
