WHITE-BREASTED SEA EAGLE. 5b 
Nidification.—The white-breasted sea eagle breeds during the 
months intervening from July to November, its nest being placed in 
the fork of some tree, oftentimes not very high up, in some secluded 
spot not far from the beach. It is composed of sticks lined with 
fine twigs of coarse grass, and the eggs, generally two in number, 
though three occur at times, are of a dusky white, finely marked 
with numerous irregular and angular hairlike streaks, not unlike 
hieroglyphics, and spotted with minute dots of reddish-brown. 
They measure 2hin. long by lgin. broad. Dr. Ramsay says :— 
“ The nest is by no means so bulky a structure as that of many of 
its allies, nor is it so large as one would expect from a member of 
the family to which it belongs. In almost every instance the 
examples found by Mr. Rainbird were placed near the tops of the 
larger trees in belts of mangroves, skirting the edges of salt-water 
swamps and marshes in the neighbourhood of Port Denison. They 
were composed of twigs and dead branches of mangrove, lined with 
a finer material. One was lined with tufts of lichen ; and in this 
instance the egg was placed on various fish-bones, shells and claws 
of crabs, &c.; the edges and sides were beautifully ornamented 
with long streamers of bleached seaweed, which gave the nest a 
novel and pleasing Spree nese 
Where found.—The white-breasted sea eagle is found on the 
coast, generally frequenting the more secluded rivers and bays of. 
northern and eastern Australia, from about the 130th meridian of 
east longitude to the 33rd degree of south latitude. It is also found 
in New Guinea, Timor, Ternate, Moro, Macassar, and Batjan. It 
is more frequent on the coast of southern Queensland than on that 
of the north, but is never found further inland than such parts as 
are under tidal influence. 

Tree-Kanaaroo ~—Dendrolayus lumholtzii. 
Discovery.—Notwithstanding that Australia was visited by 
several English naturalists during the first half of the present 
century, it was reserved for a Norseman to be somewhat recently 
the discoverer of the tree-kangaroo or boongary of the aboriginals, 
In the year 1880, Carl Lumholtz undertook an expedition to Aus- 
tralia, partly for the object of making collections for the museum of 
the University of Christiania. His travels, which occunied four 
years, included expeditions in South Australia, Victoria, New South 
Wales, and Queensland. He advanced about 800 miles into 
Western Queensland, but as the results in no wise corresponded to 
the hardships he had to endure, he returned and selected Northern 
Queensland as the field of his chief exploration, and he there spent 
fourteen months in constant travel and study. From Aug., 1882, to 
July, 1883, he maie his head quarters in the valley of the Herbert 
River. He there lived with the blacks whom he characterised as 
the lowest of the whole human race. From these associates he 
obtained information of the existence of the boongary, which seemed 
to him to be unknown to science, but the more he searched for this
