18/7.] BIRDS OF TONGATABU, FIJI, ETC. 725 



Among the specimens before me Nos. 17, 32, and 49 (Fiji) are 

 adult and fully coloured, which are very rare in collections, and give 

 me a good opportunity of making a close comparison of them with 

 Javan specimens of the true Lalage terat (Bodd.), with which the 

 Central-Polynesian bird has hitherto been confounded. I have 

 myself stated (J. f. Orn. 1872, p. 130) their undoubted identity ; but 

 having then seen only young and a few old specimens in bad condi- 

 tion, I was misled. The series before me seems to confirm the views 

 of Mr. G. R. Gray, who keeps the Polynesian bird separate. 



The latter may be distinguished from L. terat by the grey or 

 brownish-grey rump and upper tail-coverts being always barred by 

 irregular but distinct cross lines, the rump being of a uniform grey 

 with faint darker traces in L. terat — by the black shaft-stripe on 

 the white middle row of the upper wing-coverts, which is wanting in 

 L. terat — and by the narrow brownish external margin of the pri- 

 maries and first secondaries, which in the old L. terat are white. The 

 latter besides shows a distinct greyish tinge on the breast and sides, 

 whereas in L. maculosa the whole undersurface is pure white. The 

 young bird, although much more like L. terat, may be distinguished 

 by the much broader cross bands on the sides of the uuder-surface 

 and on the rump. 



The distribution of L. maculosa seems confined to the Central- 

 Polynesian Islands, Fiji, Tonga, and the Navigators'.
