Astur (Leucospiza) Nove-Hollandie, Kaup, Class. der Siug. und Vog., p. 119.

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, isq. 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 . : : . ; : ; : Vok ft Elie
Astur testaceus (Hrnest.), 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.

Astur radiatus, Cuv. Reg. An., 1829, p. 332.
Nisus (Urospiza) radiatus, Kaup, Mus. Senckenb., 1845, p. 259.

Accipiter approximans, List of Birds in Brit. Mus. Coll., Part I. 2nd edit. p. 74.
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. Astur cruentus, Gould , : : : Vol 1 Ris

Astur cruentus, Gould in Proce. of Zool. noc., Part X. p. 113.

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 Kssington.

Precisely similar in all its actions and in its economy to the Sparrow Hawk, Accipiter nisus of Europe.
