Adult. Very similar to -6'. hassana, but easily distinguished by the 

 greater length of the bare patch, which extends down the middle of 

 the throat and foreneck for about 6 inches, and by the colour of 

 the tail-feathers, which are brownish black instead of pure white. 

 Tail composed of 12 feathers. Iris pale yellow ; naked skin on the 

 sides of the face and down the middle of the throat bluish black ; 

 feet livid. Total length about 31 inches, culmen from feathers on 

 forehead 3-5, wing 18-18-3, tail 7-5, tarsus 2-35. 



An immature bird with the head and neck like those of the adult, 

 and the rest of the upper parts smoky brown mixed with white, 

 especially on the upper back, has the chest and rest of underparts 

 white, each feather with a pale brown middle and submarginal band, 

 producing a mottled appearance. 



Ilah. Coasts of South Africa, ranging north to Loango on the 

 west, and Zanzibar on the east. 



* There can be no doubt that tlio bird described is S. capensis : possibly a 

 iiiisUike may have becu made in the locality or the label have been aceideutally 

 changed.
