 ? juv. „ 25th July. ,, 120 mm. 



Iris yellow; bill red at the base, tip yellow ; feet red. 



This bird was common in small flocks in the riverside 

 trees. I once saw three, which 1 took to be males of this 

 species, sitting one behind the other on the bough of a douni- 

 palm, and solemnly bowing in unison to two others on 

 another bough, who were not taking the slightest notice. 

 Their behaviour is much more that of Starlings than of 

 Shrikes. 



Prionops cristata intermedia.

(J ad. Tsavo River. 25th July. Wing 115 mm. 



This Helmet Shrike was common in small flocks up to a 

 dozen. 



Shelley (Birds of Africa, v. p. 487) considers this bird is 

 probably the adult of P. vinaceigularis Richmond ; but as 

 Oberhoiser (P. U.S. N. M. xxviii. p. 924) refers to the latter 

 as "this very distinct species," 1 have adhered to Sharpens 

 name. Otherwise P. vinaceiyularis has priority.
