 the others by five inches and three quarters, and webbed only for 

 about three inches at the end ; legs grey. 



Inhabits Siam. — M. Temminck enters this as one of the species 

 of his Drongo Genus ; all of which have the toes placed three before 

 and one behind ; but the Paradise Cuckow has the toes two and two* 

 as in others of the Cuckow Genus; it should therefore appear that 

 the circumstance of the outer tail feathers being elongated in a similar 

 manner to those of the Malabar Shrike, might lead to this deter- 

 mination.
