Cercomela spectatrix, sp. nov. 
This species is allied to Cercomela melanura and C. scoto- 
cerca, but differs from both species in its clearer grey, less 
brown colour. Above it is grey with very little brown 
tinge, and below throat and underparts dirty white, chest 
and flanks browner, as also are the ear-coverts. Wings and 
tail brown. It may possibly be nearest to Cercomela dubia 
Blundell and Lovat, from Abyssinia, which has been con- 
sidered a race of C. melanura, but it differs by its paler and 
greyer colour, as well as by its shorter and browner tail. 
Its tail, in fact, is distinctly short for a Cercomela. 
Type 3, collected at 1000 ft. 10 miles inland from Las 
Khorai, in Hastern British Somaliland, 10th February, 1919, 
by G. F. Archer. 
Wing 82 mm, tail 55, bill 14. 
This species is named from its extremely tame, not to say 
inquisitive, nature. 
Micropus somalicus, sp. nov. 
In colour close to Micropus murinus murinus, though 
slightly greyer and less brown, but differing from that 
species in that the whitish colour of the throat is of greater 
extent, reaching almost to the breast, and also by its much 
smaller size—wing 152-156 mm. against 165-175 in IZ m. 
murinus. This species differs from the Abyssinian Micropus 
apus shelleyt, which it resembles in size, and which my 
possibly prove to be its nearest relative, by its paler and 
greyer colour above and below. 
Type 3, collected at Bihendula, British. Somalitand, 
31st March, 1919, by G. F. Archer. 
Wing 156 mm., tail 65. 
Alemon hamertoni tertia, subsp. nov. 
Differs from Alwmon hamertoni and A. hamertoni altera 
by its much more sandy, almost sandy-rufous, coloration. 
A good series of this race has now been sent home by 
Mr. Archer, and it appears to be quite a constant form. It 
is found on the Tuyo and Arori Plains not far from Burao
