508 Mr. W. R. Ogilvie Grant on the 



The differences between these species and the Luzon bird 

 may be briefly tabulated tlius : — 



The sixth primary longest, slightly longer than tlie 



fifth ; wing ca. 21 inches C. speholuni. 



The fourth primary longest, distinctly longer than 

 the fifth. 

 Upper parts olive, washed with rufous, especially 

 on the forehead and outer webs of the quills ; 



wing ca. 26 C miiiutd. 



Upper parts olive-green. 



Size larger ; wing ca. 2'6 C. catifanif. 



Size smaller: wing ca. 2"2 C. cnntilhiDs. 



The present species may be further sliortly described as 

 resembling C. minuia, but at once distinguishable by the 

 shape of the wing, which is much smaller, difl^erently shaped, 

 and more rounded, as well as more rufous in colour. The 

 underparts are white shaded with olive-grey on the breast 

 and sides, while in C. minuta the breast, sides, and flanks 

 are all washed with warm buff. 



^ . Total length 5'5 inches, wing 2*15, tail 2o, tarsus 10. 



? . Total length 5-3 inches, wing 2-1, tail 2-3, tarsus 0-9.

This interesting new Rlackbird is perhaps most nearly 

 allied to M. poliocephala CLath.), from Norfolk Island, which 

 may be at once distinguished by its much smaller size and 

 pale brownish-grey head ; it is also nearly related to 

 M. papuensis'^, De Vis, but the following comparative 

 descriptions will show the points in which they differ : — 



* I have examined the type specimen described below, and the head 

 appears to me to be exactly of the same colour as the back ; the najye is 

 sliglitly paler.— W. R. (). G.
