HALCYON SORDIDUS, Goud. Sordid Halcyon. Halcyon sordidus, Gould in Proc. of Zool. Soc., Part X. p. 72. I possess two specimens of this species of Halcyon, which were killed by Mr. Bynoe on the north coast of Australia; unfortunately they were unaccompanied by any information respecting their habits and economy ; they appear to be fully adult, and equal in size the Halcyon collaris,—a species, which, although said to be Australian, I have no authentic evidence of its ever having been killed therein. Head, back, scapularies and wing-coverts brownish oil-green; wings greenish blue, gradually changing into green on the tips of the tertiaries; collar round the back of the neck and all the under surface buffy white ; tail greenish blue ; upper mandible and tip of the lower one black; base of the latter flesh-white. The figures are of the natural size. Se Ne Oe Ve aed .
