Deep plantar tendons coracine, i.e., hallux connected with the 

 flexor perforans digitorum (fig. 2e, p. 2) ; palate desmoguathous 

 (fig. 5, p. 5) ; ambiens muscle absent. 



In addition to the families of Eollers, Bee-eaters, Kingfishers, 

 Mouse-birds and Hornbills represented in South Africa, the Motmots 

 and Todies of the neotropical region and perhaps the Madagascar 

 Eoller (Lcptoso7natidce) should be included in the sub-order. 



Family I. CORAOIIDJE. 



Bill stout, corvine in shape, the upper mandible toothed near 

 the end ; the outer toe united to the middle one at the extreme 

 base only, so that it is reversible at will, the inner toe united to the 

 third by its basal joint ; nostrils at the base of the mandible ; 

 dorsal feather tract well defined on the neck and forked on the 

 upper back (fig. 1, p. 2) ; oil gland present but nude ; caeca present. 



This family is confined to the temperate and tropical portions 

 of the old world.

This genus contains the Eollers, birds of bright plumage and 

 powerful flight, spread over the greater part of Europe, central 

 and southern Asia as far as Celebes, and the whole of Africa.
