M. L. Albertis on Birds collected during 
I met with this bird while remaining for two days at the same 
anchorage. I saw about fifty coming to sleep on a very high 
tree in the evening, and starting in the morning a little after 
sunrise; but the bird is very shy, and for this reason not easy 
to be killed. The Cyclopsittacus fuscifrons is a very small 
Parrot, one of the smallest, and difficult to find in the dense 
foliage of the trees; but it is often brought to notice by its 
piercing whistle. It is not shy; and once find the tree on which 
it feeds, and it is easily secured. It is very similar to an 
allied species which I discovered at Hall Sound, named by 
Mr. Sclater Cyclopsitta suavissima, and resembles it in its 
habits. 
Chalcopsittacus chloropterus is described by Prof. Salvadori 
as a new species; but, indeed, I cannot see how this bird is 
to be distinguished from C. scintillatus ; for the distinctive 
characters pointed out by Salvadori I consider dependent 
only on the age, and not constant in all individuals of 
different age and different sex. Many other birds of this 
family may be added to my list by other explorers; for I saw 
many, especially among the Charmosynce ; but as I did not 
kill them, I do not mention them. 
Buceros ruficollis is a common bird all over New Guinea, 
still I cannot say whether in the interior I saw this species, or 
another one, which is perhaps intermediate between B. ruficollis 
and the Buceros of the Solomon Islands; for I found some beaks 
of this bird in the houses of the natives so much smaller, al¬ 
though of adult birds. Therefore I am inclined to believe 
they may belong to a new species. 
Among the Kingfishers there is, according to Salvadori, 
another new species— Cyanalcyon stictolcema ; but I do not 
think it is a good species, and I believe the differences pointed 
out by him between this bird and C. nigrocyanea only de¬ 
pend on the sex or age of the specimen he had under his con¬ 
sideration. A specimen which I got in the same locality where 
I had the first one is by no means different from C. nigro¬ 
cyanea of the Aru Islands. 
An elegant bird which attracts the attention of the traveller 
is the Dendrochelidon mystacea, from its peculiar shape, and 
from the length of its wings and its forked tail. It is seen in
