Genus ZOSTEROPS, _Vig. & Horsf._ Three well-defined species of this genus inhabit the continent of Australia and Van Diemen’s Land; two are found on Norfolk Island, and numerous others inhabit the Indian Islands and the continent of India even to the Himalaya Mountains. In placing this group next to the Honey-eaters, I have been influenced by their approximation to those birds in some of their habits: they also exhibit a further degree of affinity in the form and structure of their nest, but not in the colouring of their eggs, which are always blue in colour. 334.

The family _Cuculidæ_ is very fairly represented in Australia, since we there find species belonging to the greater number of the Old World genera, and one, _Scythrops_, which has not hitherto, I believe, been found elsewhere. With the exception of _Centropus_ and _Eudynamys_, they, like their prototypes, are parasitic in their nidification, and depend upon other birds for the hatching of their eggs and the feeding of their offspring. Genus CUCULUS, _Linn._ 337. Cuculus optatus, _Gould_ Vol. IV. Pl. 84. Since my description of this species was printed I have seen specimens from India, with the name of _Cuculus micropterus_ attached to them: should this name have been published prior to the one I have assigned to it, my name must sink into a synonym. 338.

Cuculus dumetorum, _Gould_ This species, which inhabits the north-western coast, differs from _C. insperatus_ in being of a much smaller size and in the whole of the plumage being of a browner hue. Genus CHRYSOCOCCYX, _Boie_. The members of this genus are distributed over most parts of the Old World; two species occur in Australia. 342. Chrysococcyx osculans.
