This is a peculiar species of Cuckoo, having- the black coloration of a Koel ( Eudynamis ), but with the 
nostrils of a true Cuckoo (Cuculus). Its bill, however, is abnormally broad, and it forms an interesting link 
between the two genera above mentioned. 
It was originally discovered at Lobo in New Guinea by the well-known traveller Solomon Muller, and in 
the north-western portion of the same island it has been met with at Mum by Dr. Meyer, at Andei by Baron 
von Rosenberg, and at Warbusi by Dr. Beccari. The latter naturalist says that it is one of the rarest of birds 
in the north-western portion of New Guinea. Mr. Bruijn has received it from Salwati, and in the south- 
eastern part of New Guinea Signor D’Albertis met with it on the Fly River, and Mr. Forbes has procured 
specimens in the Astrolabe Mountains, at Moroka (alt. 5000 feet), and in the Sogeri district at a height of 
2000 feet. 
So far as is known, the present species is only found in New Guinea and Salwati. Dr. Finsch gives 
My sol as a habitat, but apparently in error, as no specimens from this locality are in the Leiden Museum. 
r Ihe late Mr. Blyth described the species as from Borneo; but he afterwards corrected this, and stated that 
it was from “ an islet off the coast of Waigiou,” where, however, no recent traveller has obtained it. There 
is at the same time no improbability in the occurrence of the species in either of the above-mentioned 
islands. 
The following is a description of the pair of birds procured by Mr. H. O. Forbes: — 
Adult. General colour above glossy blue-black ; quills and tail black, with a gloss of blue-black externally ; 
a broad line of white feathers along the centre of the crown to the nape ; sides of face and under surface of 
body black, the breast and abdomen more ashy, the long under tail-coverts barred near the end and tipped 
with white; under wing-coverts black, with a few white bars: “bill black; feet blackish lead-colour; iris 
chestnut-brown” (U Albertis). Total length 125 inches, culmen F25, breadth at gape 055, win<>- 06 
tail 6 0, tarsus 0’85. 
Young. Differs from the adult in being more dingy black, and in having white bars on the breast, under 
tail-coverts, and under wing-coverts, and a white tip to the tail-feathers. Total length 12 inches, culmen 
Tl, wing 6 - 3, tail 5‘8, tarsus 0-85. 
The figures in the Plate represent an adult and young of this curious Cuckoo, of about the natural size • 
they are drawn from the above-mentioned specimens collected by Mr. Forbes.
