226 OXYNOTUS 
Well (Knutson), and Ndian. At the last place Mr. Sjéstedt 
saw them on two occasions in the high trees. Their note 
is a shrill repeated cry, and their food consists of grass- 
hoppers and other insects. 
Du Chaillu procured the species at the Camma River, in 
Gaboon, and Lucan and Petit in the Loango district of the 
Lower Congo at Chissambo, Majumba and Ungomongo. 
The north-eastern limit for this Cuckoo-Shrike is the Ubangi 
River, one of the northern tributaries of the Congo, where 
it has been met with by Mr. Dybowski, while a single 
example was recently procured by the Ruwenzori expedition 
on October 17 in the Ituri forest of the Congo Free State, 
at an elevation of 3,000 ft. 
Like all the African members of this genus, nothing is 
yet known regarding its nest and eggs, which I presume 
are hidden among the upper leafy boughs of the tall forest 
trees, and the nests are probably very similar to those of 
Campephaga nigra which have been described. 
Genus IV. OXYNOTUS. 
Very similar in general structure to Coracina, but the sharp ends to 
the feathers of the back less strongly pronounced. They are smaller birds, 
and the sexes differ in the upper parts being grey in the males and brown 
in the females. Primaries, 4th longest, 1st quite half the length of 4th.
