350 Mr. A. R. Wallace on some new Birds 



Total length about 14 inches; wing 4 inches. 



Hab. Morty Island. 



In the young bird there are numerous oval buff spots on the 

 middle of the back, which do not occur in the young of any of 

 the other species. 



Remark. — This species differs from its allies in the large white 

 dorsal spot; from T. sabrina, G. R. G., which has a small dorsal 

 spotj it differs in the much lighter blue of the crown, which is 

 sharply defined behind : in general coloration it more nearly re- 

 sembles T. isis, G. R. G., but is rather larger, and has the tail- 

 spatulse more like T. galatea, G. R. G. It seems to be confined 

 to the small island of Morty, only separated by a strait 30 miles 

 wide from Gilolo, the habitat of T. isis.
