coLsidered as nuchalis (from the West-side of Victoria Nyanza) 

 for, according to v. S[omeren (op. cit.) this has "a dark brown 

 head with a few dark markings", which does not agree with any 

 of the ones before me. Reichenow (Vog. Afr. Ill, p. 555), 

 who is the author of the bird, gives the wing to 55 mm., Neu- 

 mann gives 54 mm., but v. Someren 63—66 mm. for cT, 

 54—60 mm. for 9- A number of these specimens recall, as regard 

 the colour of the head, the north-east African robusta, but do 

 not attain the measurement of that form. With respect to the 

 colour of the lower surface these 13 specimens exactly resemble 

 those from tho Kikuyu country. 



The young birds from the Elgon district differs distinctly 

 from the full-grown in the tail-feathers being dark greyish brown, 

 and all of them have a distinct whitish tint on the under parts 

 (in these characters they recall naialensis to a certain extent). 

 The head has not yet acquired the brownish red colour of the adult 

 but is of the same colour as the back and provided with dark, 

 wide streaks.

This little Grass-Warbler was only seen on this one occasion 

 in the grass-plains, in the vicinity of Nairobi, v. Someren 

 (Ibis, 1916, p. 452) says, however, of this race that it is "fairly 

 common, but difficult to procure". 



Breeding-time seems to fall in the month of April, for this 

 female specimen had well developed eggs in the ovary. In 

 contradistinction to the following this form is considerably lighter
