 maxillo-palatiues are fused i'or their entu-e length, though grooved 

 and even fenestrated in the middle. The palatines are comjjletely 

 fused together posteriorly, where the external lamina is absent. 

 In front the two bones gradually get broader and diverge from

 and nearly meet where a small splint of bone (a vomer) is wedged 

 between them. The palatine bones are very deep, the ascending 

 lamina being large. The pterygoids are hammer-shaped bones, 

 their junction with the palatines being expanded in a vertical 

 direction. 



In other Cuckoos the palatines have not a well-developed 

 ascending lamina, there is no fusion posteriorly or approximation
