NILAUS MINOR 455 
stripes and slightly smaller size, wing 2°65 to 3°0 against 
2°85 to 3°05 in N. a. minor. This form has only been 
obtained by Erlanger in south-central and south Somaliland 
at Kismayu. 
Nilaus afer massaicus, larger than either of the others, 
wing 3'0 to 3°4; flank stripes darker. From Kilimanjaro in 
German East Africa to Kikuyu and Ukamba in British East 
Africa. 
I have not been able to examine examples of the southern 
Somaliland race, but I find that nine males from British Hast 
Africa, chiefly from the Jackson collection, average 3°05 
(extremes 2°8 to 3°2), while six from Somaliland average 3°0 
(extremes 3°0 to 31). I see myself, therefore, no ground for 
separation of the two forms. 
Pease noticed the Lesser Brubru in the upper branches of 
high trees, where it searches for its food, and is generally 
solitary ; Hawker found that it was common, and had a variety 
of calls, and was a good runner. 
Jackson discovered a nest at Kibwesi on March 6, partially 
built ; after waiting a few days to allow the birds to finish 
building and lay the eggs, he secured them. The nest, about 
3 inches in diameter, was neatly made of lichen and lined 
with fibre, and was placed on the branch of an acacia tree at a 
height of 25 feet. It was not unlike that of an English 
Chaffinch. The eggs, two in number, were of a dark grey 
stone-colour, rather sparingly spotted with black, and with 
larger spots of dark brown shading into the ground colour at 
their edges. 
Erlanger also found the nest of this species in the Gura 
country of Somaliland on April 8; it contained two eggs. 
He gives a very similar account to that of Jackson, also 
remarking on the similarity of the nest to that of the 
Chaffinch. In this case the eggs measured 0°72 x 0°60,
