3. EUCORYSTES. 



Eucorystes, Sclater, Ibis, 1883, p. 147 



This form is easily distinguishable from Ocijalus, wilh which it 

 has been usually united, by the much shorter wings, and the totally 

 different shape of the bill and frontal shield. The biU is much 

 produced and compressed towards the apex ; the frontal shield is 

 enormously developed, covering the whole front of the head up to the 

 vertex.
