southwards by the more yellowish-green colour of the upper- 

 parts whieh are less heavily streaked with blackish. I cannot, 

 however, distinguish between tlie other subspecies -which he 

 admits and think they should all three be united under the 

 name S.c.hijpostictus, ranging from Lake Naivasha through 

 the Lake District to Nyasa.
