GENTLEMEN, 
Will you do me the favour to insert in your next Number 
the following descriptions of two birds from Eastern Australia, 
which I believe to be new to science, and oblige - 
Yours very faithfully, 
JoHN GouLp. 
Cuculus (Cacomantis) castaneiventris. 
Chin, ear-coverts, crown, and upper surface deep purplish 
grey ; all the under surface, including the under tail-coverts, 
bright chestnut-red; wings brown, glossed with olive; upper 
tail-coverts and tail deep greyish purple; all the feathers tipped 
and the lateral ones toothed on their inner web with white, which 
assumes on the two outer ones the appearance of interrupted 
bars; bill purplish black; legs and feet orange; nails black. 
Total length 94 inches; bill %, wing 44, tail 5, tarsi 2. 
Hab. The Cape-York district of Queensland, Eastern Aus- 
tralia. 
Remark. This bird is much smaller than Cacomantis flabelli- 
formis, and, moreover, has much shorter wings, but assimilates 
very closely to that species in form and contour; it differs, 
however, not only from that and every other Australian cuckoo, 
but from all others I have yet seen from the islands to the 
northward; it is closely allied to a species inhabiting the 
Philippine Islands which I take to be the Cacomantis sepulchralis 
of Bonaparte, and more distantly to the Cacomantis bronzina of 
G. R. Gray. 
Ptilotis notata. 
Crown and all the upper surface greenish olive ; lores, a line 
beneath the eye, and the anterior portion of the ear-coverts 
brownish black ; from the angle of the mouth a pale-yellow 
stripe; posterior part of the ear-coverts pale yellow, assuming 
the form of a nearly round spot; under surface pale greyish 
olive, obscurely streaked with pale grey down the throat and 
breast; bill black, with a thick fleshy yellow gape; legs 
bluish. 
Total length 64 inches; bill 1,4, wing 33, tail 24, tarsi 4. 
Habitat. The Cape-York district of Queensland, Eastern 
Australia.
