Genus MYZOMELA, _Vig. & Horsf._ Five well-marked species of this genus are distributed over Australia; numerous others are found in New Guinea and the neighbouring islands; the form also occurs in the Polynesian Islands, but is not found in Van Diemen’s Land. 316. Myzomela sanguineolenta Vol. IV. Pl. 63. 317. Myzomela erythrocephala, _Gould_ Vol. IV. Pl. 64. 318. Myzomela pectoralis, _Gould_ Vol. IV. Pl. 65. 319. Myzomela nigra, _Gould_ Vol. IV. Pl. 66. 320. Myzomela obscura, _Gould_ Vol. IV. Pl. 67. Genus ENTOMYZA, _Swains._ Two species of this well-defined genus are comprised in the Australian fauna, one of which inhabits the south-eastern parts of the country, or New South Wales; the other, which so far as we yet know is strictly confined to the north-eastern coast, is very plentiful at Port Essington and in the neighbouring districts. The form appears to be confined to Australia, for I have never seen it from any other country. 321. Entomyza cyanotis Vol. IV. Pl. 68. This bird has the habit—a somewhat remarkable one among the Honey-eaters—of selecting the nest of _Pomatorhinus temporalis_ for the reception of its eggs. 322. Entomyza albipennis, _Gould_ Vol. IV. Pl. 69. Genus MELITHREPTUS, _Vieill._ No one group of birds is more universally distributed over Australia than the _Melithrepti_, for their range extends from Van Diemen’s Land on the south to the most northern part of the continent; and they are equally numerous from east to west, each part of country being inhabited by a species peculiarly its own. The _Eucalypti_ are the trees upon which they are almost exclusively found. I believe the form is unknown out of Australia. 323. Melithreptus validirostris, _Gould_ Vol. IV. Pl. 70. 324.

Pl. 74. 328. Melithreptus melanocephalus, _Gould_ Vol. IV. Pl. 75. _Certhia agilis_, Lath. Gen. Hist. vol. iv. p. 204. Genus MYZANTHA, _Vig. & Horsf._ During the progress of this work three additional species of this genus have been discovered, one in the interior of New South Wales, the second at Swan River, and the third on the north-west coast; consequently it is a genus the members of which are widely distributed over nearly every part of Australia.
