Distribution. Celebes — Minaliassa (Forsten bi, Meyer 9, Pisclier 11 etc.)] Gorontalo 
(Forsten h 1, Meyer 13)] Talissi Island (Griiillem. 15)] Banka, Leinbcb and Mante- 
hage Islands (Nat. Coll.); Togian Islands (Meyer 1.3)] Macassar (Wallace 20)] West 
Celebes (Dolierty 23)] E. Celebes, and Peling (N at. Coll.); Sidalslands (Allen a 1, 20). 
Briiggemann (11) records a specimen as baring come from Sangi, but this 
would appear to be a mistake, since that island has a race of Eudynrmiis of its own, 
E. mindanensis sangirensis W. Bias. 
In the foregoing sketch of the several stages of dress passed through by 
this Cuckoo a conclusion has been arrived at identical with that of Capt. 
Shelley, but differing radically from those of Lord Walden, Briiggemann, 
Dr. Guillemard, and Prof. W. Blasius. According to Shelley the adult 
male “is all over blue-black, the adult female above chestnut evenly barred with 
olive-black, . . . under parts (except chin and upper throat) buff, with numerous 
narrow wavy black bars”; Briiggemann, on the other hand, states that the sexes 
are alike both in size and colour, and Avhat Shelley describes as the adult female 
is held by him, Walden, Blasius and Guillemard to be the first stage of 
immature dress. That these authorities are in error is shoAvn by the nestling 
obtained by the Drs. Sarasin, as also, by the specimen described by us as 
c [g] with earliest appearances of adult plumage, to which attention may 
be drawn. Here the new and groAving feathers are barred Avith black and 
rufous brown, while the old Avorn feathers, Avhich were about to be cast off, 
are of that more uniform broAvn appearance belonging to the fledgeling, but 
supposed by these authors to belong to a more advanced stage. As a great 
series before us in almost every phase of dress shoAv, the young of both sexes 
are at first apparently just alike in coloration, but commence to deviate in the 
second stage, becoming more and more different as they approach maturity. 
Dissimilarity of the sexes is one of the characteristics of the genus Eud^namis, 
elseAA'here, as Indian ornithologists Avell knoAA^ 
There is a remarkably close resemblance betAveen the old female of this 
(hlebesian Cuckoo and the young of the AA'ide-spread Centrococcyx henyalensis 
also a species occurring in Celebes. The young dress of E. melanorhyncha 
recalls the uniform coloration of the upper surface of Corxystes coromandus. 
The only specimen as yet known from the Sula Islands is a male, appa- 
rently partially affected by albinism, Avhich Avas obtained by Mr. Wallace’s 
assistant, Allen, in Sula Besi or Sula Mangoli, and was named as distinct on 
account of its smaller size. This distinction is not found to hold good by 
Capt. Shelley, and until more specimens for comijarison are forthcoming it 
should be regarded as identical Avith E. melanorhyncha. Shelley’s opinion is 
confirmed by an example from Poling, resembling the birds of the mainland.
