The following is an extract from his Journal:—“October 2. Found, for the first time, the eggs of _Tinnunculus Cenchroïdes_, four in number, deposited in a hollow spout of a gum-tree overhanging a creek; there was no nest, the eggs being merely deposited on a bed of decayed wood.” They are freckled all over with blotches and minute dots of rich reddish chestnut on a paler ground, and are one inch and five-eighths in length by one inch and a quarter in breadth.

I think Professor Kaup is right in proposing a new generic title for this species, differing as it does both in structure and habits from the true _Asturs_; he also, like myself, considers the white birds to be merely albino varieties of the other; but my friends, the Rev. T. J. Ewing and Ronald C. Gunn, Esq. of Van Diemen’s Land, are both most decidedly opposed to this view of the subject, and found their dissent upon the circumstance of there being none other than white individuals in Van Diemen’s Land. So far as it is at present known, the southern and eastern portions of Australia and the island of Van Diemen’s Land constitute the habitat of the species. 16. Astur radiatus Vol. I. Pl. 16. _Astur testaceus_ (_Ernest._), Kaup, Isis, 1847, p. 367. A curious form not quite agreeing with _Astur_; it is very rare, and nothing whatever is known of its habits. 17.

The _Astur approximans_ has been with propriety removed to the genus _Accipiter_ by Mr. G. R. Gray, and to this genus my _A. cruentus_ is also referable; for although of a larger size than the other members of that form, their structure, except in the shorter middle toe, is very similar. 18.

This species and the preceding are representatives of each other in the eastern and western portions of the continent. I have lately seen specimens from Port Essington. Genus ACCIPITER, _Briss_.
