divided into three facets, two diversely declining from each corner — 
namely, a larger one on the outer side (i), and a smaller one facing in- 
wards on the inner side of the end for the pterygoid {k), and a smaller 
one (I), posterior to the others ; the middle of the outer ventral edge 
of the bone (m), which, in Haliaetus, is expanded in order to increase 
the articulating surface, performs the same service in the fossil, 
but is very much thicker and more protuberant. The owner of 
this quadrate was as strong in the beak as on the wing. Locality, 
Kalamurina. 
In the proceedings of the Linnsean Society of New South Wales, 
Vol. 6, at p. 123, is a note proposing that the Eagle described in 
the Proceedings of the Royal Society of Queensland, Vol. 6, p. 161, 
under the name Uroaetus brachialis should be removed to a new 
genus, Taphaetus, on the ground that an aquiline femur figured 
and described in the note, and assumed to be cospecific with the 
humerus. U. brachialis, could not belong to the living genus, Uroaetus. 
This proposal is largely based on the improbability of two large 
eagles co-existing in the same fauna and locality. Now that we have 
proof that two birds of the kind were contemporary, it seems 
advisable to restore brachialis to Uroaetus, the genus to which 
its humerus allies it. In placing the humerus and quadrate 
now described in the same genus as the femur of the note, the writer 
is led by a desire to avoid multiplication of names on insufficient 
grounds. The femur is 7 J mm. shorter than that of a female 
of Uroaetus audax, but this measurement is estimated after a con- 
jectural restoration of the condylar region, and may be somewhat 
defective. The humerus, on the other hand, is decidedly larger 
than that of Uroaetus audax. We must therefore either propose 
a new genus for the latter fossil, or regard Taphaetus as a rather 
short-legged eagle, a course which for the present seems preferable.

Asturaettts furcillatus U.S. 
Tibiotarstjs. — Plate I., fig. 3. — A right tibiotarsus, wanting 
the cnemial crest, but otherwise well-preserved. A cnemial 
crest produced but slightly, if at all, proximad of the articular 
surface of the head, a fibula anchylosed to the shaft at its distal 
end as well as to the peroneal ridge, and a broad low distal joint with 
low ridged malleoli, of which the inner on the post axial side inclines 
ventrad at a much more acute angle than the outer, — these features 
combined afford good guidance to the tibias of the Australian 
Falconidw, exclusive of Pandion. But to discriminate between 
the tibias of the genera wherein the bones are nearly the same 
in size and porportions — namely, Haliastur, Astur and Lophoictinea — 
is no easy matter, for these are all very much alike. Happily, 
it is not necessary to attempt to do so now, since the tibia of the 
extinct falconine bird named in the title is sufficiently distinguished 
from all of them by characters of its own, observable on its almost
