the Exploration of the Fly River. 
the daytime at rest on some high dead tree; and in the even¬ 
ing and in the morning it flies about chasing the insects on 
which it feeds. 
Flycatchers were very scarce; and, indeed, I cannot mention 
more than the beautiful Monarcha chrysomelas, which I had 
never collected before, and only saw once from New Guinea* 
in Mr. Stone's collection, and which is found also in the 
Solomon group. Campephaga sloetii is a rare bird in collec¬ 
tions; but it seems to be distributed all over New Guinea, as 
I have found specimens on the Arfak, at Hall Sound, and 
lately far up the Fly River, and there the most numerous ; but 
I could not get more than one, which I met with in a native's 
garden, feeding on the small berries of a high tree. Along 
the banks of the river, or on some gravel-flat of the river's 
bed, when the water was low, I saw another interesting small 
bird, which I discovered in the streams of Mount Arfak, in 
1872. It is a lively bird, and is often seen giving chase on 
the wing to insects, on which it lives. It has been named 
by Salvadori Monachella saxicolina . The Artamus leuco - 
gaster is an Australian bird, but very common also in the 
eastern and central part of New Guinea. Its abode is on 
some old trunk projecting in the river's bed. There it is 
often seen waiting for insects, which it catches in flying, not 
unlike a Swallow. Near to the mouth of the river I found 
two little gems of the feathered family, Nectarinia frenata 
and N. aspasia. The first one is an Australian and Papuan 
bird; the second inhabits all New Guinea and many islands 
east and west of the same island. Perhaps on account of the 
flowerless season, the Meliphagidse were scarce in number and 
species; but it is not improbable that I have found a new 
genus of this family. Only two species of Eupetes had been 
known for many years as inhabitants of New Guinea. Lately 
some new ones have been added-—one from the west, the 
other from the east. The last one is also found in the bush 
up Fly River, and it has been named Eupetes nigrocrissus by 
Salvadori. Other species of this genus will be found in New 
Guinea; so I think it will not be considered absolutely a
