LANIARIUS LEUCORHYNCHUS 331 
and legs black in the dried skin. Total length 8:0 inches, culmen 0:90, 
wing 3°5, tail 3-7, tarsus 1:2. Umfudu, 3, type, 24. 6. 01 (Erlanger). 
Erlanger’s Black Boubou was named after the discoverer 
by Reichenow. It is only known from the two original male 
examples obtained at Umfudu, on the Juba River, about 
75 miles from its mouth in south Somaliland, on June 16 
and 24, 1901; these, through the courtesy of Carolina, 
Baroness von Erlanger, I have been able to examine. 
Laniarius nigerrimus.

Adult. Black, with a greyer tinge on the lower back and breast and 
with a slight gloss ; rump with the soft feathers grey basally with black tips, 
but without or with only traces of the white subterminal markings; tail 
longer than the wing. Iris reddish brown; bill black, feet slate-grey. Total 
length 8 inches, culmen 0°85, wing 3°3, tail 3:4, tarsus 1°25. Lamu (Kirk). 
This Boubou was first discovered by Fischer at Kipini, 
near Lamu on the coast of British East Africa. I have 
two examples of the species, procured for me by Sir John 
Kirk at Lamu. These are now in the British Museum. 
Reichenow doubtfully refers to this species a Boubou 
obtained by Emin at Loramo, in the Nile Province of 
Uganda. 
It can be easily distinguished from L. holomelas by its 
grey rump and its proportionately longer tail.
