278 Mr. R. B. Sharpe on the 



saw, the characteristic rolling motion observed in that of Cura- 

 cias ahyssinica and Coracias pilosa. I have seen these birds 

 {E. afer) in company with C. pilosa and Caprimulyus inornatus 

 hawking the ants which fly in the gloaming. It was procured 

 and observed only at Kokai, on the Lebka, and on the Anseba, in 

 July and August, where it was plentiful." 



Dr. Kirk (Ibis, 1864, p. 724) found it in the Zambesi to be 

 local, and observed rarely near Tete. Frequent in the river- 

 valley at Chibisa, on the river Shire. Its habits resemble those 

 of Coracias caudata. 



My description is taken from a Gambian skin in my collec- 

 tion. Abyssinian examples, of which I have two from Kokai, 

 brought home by Mr. W. Jesse, are a little larger and have 

 stouter bills ; otherwise I can see no difference.
