tween Myiagra and Muscipcta ; possessing, in 

 other respects, much more of the characters of the 

 former than of the latter. 



General colour of the upper plumage light caeru- 

 lean-blue, which spreads uniformly over all the 

 exposed parts of the wing and tail-feathers the 

 under parts are lighter and tinged witn grey, wnich 

 becomes almost white on the belly and vent ; the 

 covered portions of the tail and quill-feathers are 

 blackish ; the bristles of the mouth are strong, and 

 are two-thirds the length of the bill, which, with 

 the feet, are blackish. Of this rare species we have 

 never seen a second example.

That the foregoing outline of the circle of Myiagra 

 is founded on some solid basis, will appear more 

 probable when we compare the species, here named 

 as constituting types of form, with those of the long- 

 tailed Muscipetce and with the divisions of the en- 

 tire genus.
