318 LANIARIUS SUBLACTEUS 
rich buff. Total length 7:5 inches, culmen 0:9, wing 3:4, tail 3:5, tarsus 
1:20. Lamu (Kirk). 
The sexes are alike. An immature bird has an outer edging and tip of 
white to the outer tail-feathers and buffy-white tips to some of the wing 
coverts. 
The Zanzibar Boubou inhabits East Africa from the 
neighbourhood of Lamu and the Tana River south to Dar-el- 
Salaam and Zanzibar island. It does not appear to extend 
very far into the interior; though met with by Fischer at 
Komboko and Gros Aruscha, both localities not far from 
Kilimanjaro; but the Boubous which I have examined from 
that neighbourhood, obtained by Johnston and Hunter, must 
be referred to L. ethiopicus ambiguus. 
The type described by Cassin is stated doubtfully to have 
come from Hast Africa. On Zanzibar Island the species 
appears to be common, both Béhm and Fischer met with it 
there, while the last named also noticed it at many other 
localities from the Tana River to Bagamoyo on the coast of 
the mainland. He further states that it is known as “ Migo” 
at Zanzibar and inhabits thick bush and that its flutelike 
and clear cry consists of three notes, which is generally 
answered by the female. He found the species nesting in 
Mayon Zanzibar Island. The nest was constructed of rootlets 
and the fibre of the cocoa-nut, and was placed from 9 to 
12 feet from the ground in the crotch of a thick mango tree. 
The eggs, two in number, were pale greenish blue with 
lavender grey and dark brown irregular blotches, chiefly at 
the thick end; they measure 0°85 x 0°65. 
The British Museum has examples of this species from 
Lamu and Melindi (Kirk), Takaungu (Percival), Mombasa’ 
(Handford), all on the coast of British East Africa; from 
Zanzibar Island (Fischer) and Ugogo (Kirk), in the interior 
of German East Africa,
