Java. 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 condition, 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 primaries 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'. 5. APLONIS TABUENSIS (Gm.). A. marginata, Gould, P. Z. S. 1836, p. 73. No. 8.
