named races of C. leucntis, and in working them out I find 

 tiiat this group and the '' striatus " group fall naturally in 

 together and do not appear to overlap in any part of their 

 extreme limits. Therefore I agree with Zedlitz (cf Journ. 

 fiir Orn. 1910, p. 755), that C. leucotis and its subspecies 

 should in future be placed under C. striatus ; thus making 

 Colius striatus the parent species and all the others geogra- 

 phical races of it, though I do not agree that C. castauolus 

 should be included also,

Of this, Colius nigriscapalis Rchw. (Journ. fur Orn. 1892, 

 p. 180 : Buea, Cameroon Mt., cf. p. 218) becomes a synonym. 



This race differs from C. s. striatus in having the forehead 

 black ; the cheeks are the same colour as the top of the head^ 

 which is rather lighter in colour than the mantle; and 

 from C s. cinerascens in lacking the white cheeks and in 

 having the under sides of the wings richer in colour. The 

 legs and toes are red as in C. .<?. cinerascens, and thus differ 

 from those in C. s. striatus. Wing-measurements : Congo,
