Dr. Heuglin’s List of Birds 
On trees and bushes in marshy places along the coasts of 
Abyssinia, Danakil, and Somali. 
[I cannot discover any material difference between the birds of 
Eastern Africa and those of the Indian Archipelago.— Ed.] 
18. Halcyon semic^erulea (Eorsk.). 
Seems to be only a bird of passage. During the whole of Sep¬ 
tember and up to the middle of October not one single specimen 
was seen on the Danakil coast. But from this time many of 
them occurred about Tadjura, Ambabo, &c. They lived in pairs 
on Mimosa and Zizyphus trees. Near Berbera (S.) more rarely 
on saline plants.
