532 LETTER FROM MR, W.J. HOFFMAN. [Noy. 2, 
the present animal should now be called. I have also obtained a second 
species of Kangaroo, which I believe to be new, but have not been able 
to determine accurately, from the specimen being immature and its 
dentition imperfect *. ‘The adult animal, of which I have seen several 
individuals in the forest, is larger than D. luctuosa. 
“In the river, along which I penetrated into the interior some way, 
Crocodiles were abundant. In two hours I saw nine, large and small, 
but only one of really considerable size. Here also near this island 
on calm days I have often seen them; and, judging from their heads, 
which they thrust out of the water, they must be of large size. They 
seem to have fixed places in which they pass many hours of the day ; 
for passing many times I always see them at the same posts. 
“Twas rather fortunate in my excursion into the mountains; for I 
found Paradisea raggiana, and obtained some beautiful specimens in 
full dress. In its voice, in its movements, and in its attitudes, it per- 
fectly resembles the other species of the genus. It feeds on fruit; and 
I could find no trace of insects in the seven individuals which I pre- 
pared. It inhabits the dense forest, and is generally found near the 
ravines—perhaps because the trees on the fruit of which it feeds 
prefer the neighbourhood of water. The female is always smaller in 
size than the male; and I find this sex less abundant, because, as I 
believe, it is the season of incubation. The female is more like the 
same sex of P. apoda than that of P. papuana. The young male is 
like the female, but often recognizable by having distinguishable traces 
of the yellow collar which in the old male divides the green of the 
throat from the breast-feathers. |The irides are of a rather bright 
yellow, and the feet lead-colour with a reddish tinge. The long flank- 
feathers in individuals recently killed have a very bright tint, which 
they lose in a few days—even in a few hours. The two middle tail- 
feathers are filiform, as those of P. apoda and P. papuana, and in 
no stage of development resemble those of P. rubra. These two 
feathers are not so long as in P. apoda, and about equal to those of 
P.papuana. Like its sister species, P. raggiana is an inquisitive bird, 
and often approaches from branch to branch within a few yards of the 
hunter, and remains motionless for some seconds to observe its pursuer, 
stretching out its neck, flapping its wings and emitting a peculiar cry, 
upon the sound of which other individuals come forward to join it. 
When one is wounded and cries out, many others come forward as if 
to protect it, and approach quite near, descending to the lowest boughs. 
The adult males frequent the tops of the highest trees, as Mr. Wallace 
observed in the other species, and as I also remarked in my former 
expedition. As regards the nidification I have as yet obtained no 
information.” 
A letter was read from Mr. Walter J. Hoffman, dated Reading, 
Pennsylvania, U.S.A., July 15th 1875, containing a sketch of a horn 
of an American Pronghorn (dntilocapra americana) with a double 
prong.

M. d’Albertis’s specimens, Ann. Mus. Gen, vii. p. 344.—P. L. 8.]
