90 Mr. Leadbeater on some new Species of Birds 



scription of a species I have received from the Cape of Good 

 Hope. This bird, although it does not exactly accord with the 

 description of the bird originally brought from the same place 

 by Dr. Sparmann, may yet be the female, or a variety of that 

 species ; the descriptions of it being very vague and confused, 

 and the identity of the species being much in doubt.

This bird has at first sight some appearance of the J.albi- 

 collis* of M. Temminck ; and on a superficial examination 

 might be pronounced either the female or the young male 

 of that species. But the bill will be found to be decidedly 

 distinct ; being shorter and stronger, and having a much more 

 acutely angulated gonys than the bill of that bird. 



I. Le Vaillantii also is of less dimensions than the former 

 bird ; and the disposition of the colours, as may be seen by the 

 above descriptions, is different in both. I have named the spe- 



* The male and female of this species had been originally described and named in 

 this paper; but as the species has been figured by M. Temminck subsequently to the 

 reading of the paper, I adopt his name. — Nov. 29, 1828.
