1862,] OP THE SULA ISLANDS. 341 



Delicate cobalt-blue, paler and with an ashy tinge on the body 

 beneath ; the belly and under tail-coverts nearly white, tinged with 

 ashy blue ; wings and tail ashy, the feathers with the outer edges 

 blue ; bill and eyelids blue ; iris dark ; feet blue-lead. 



Total length 6^ inches ; wing 3 inches. 



Hah. Sula Islands and Celebes. 



Remarks. — I have retained for this species the name attached to 

 my Celebesian specimen by Mr. G. R. Gray. In both sexes it is 

 alike, and diifers from the common M. ccerulea of th€ Malay penin- 

 sula and islands in the absence of the black crown-spot and collar.

 plex, Gould, but is a little larger, and has a more definite coloration 

 and markings.
