does not stay after the first few days of April. After this time it appears to go hoth to 

 the east and west into the mountainous parts of the White Nile. He noticed that it 

 arrived at the same time as Eurystomus afer, the African Roller, and frequented the same 

 marshy places. At sunrise they settle on the tops of the trees, after a few short turns, 

 and there remain motionless for some time, when one will suddenly start off afresh, 

 upsetting the resting-place ; and as they are accustomed to sit close together on a hranch, 

 there is great contention for a place, those that are driven off having to find another 

 perch. From the trees they descend to the water, over the surface of which they hunt 

 for insects ; hut after ahout an hour's exercise, they rise into the air and disappear, not 

 returning to the place till the next morning. The same naturalist met with the species 

 in the Adda Galla country during the late Italian expedition to Shoa, where the native 

 name was " Tobbisa." 



The description is taken from an adult bird in the British Museum, the figure in 

 the Plate being drawn from a specimen in Capt. Shelley's collection.
