large tusks of the male about 2s. 6d. per pair, while the bones make the 
best charcoal for sugar-refining. The price for oil varies from 12s, 
to 20s. per gl. After many years’ experience it has been found at 
the Repulse Bay station that the old cows yield the most oil, the 
quantity being sometimes as much as from 8 to 10 gls., but on the 
average only 4 or 5 gls. The winter months, with respect to the 
amount of oil obtained, are the most profitable time. 
Species. —Dugongs have been divided into three species, the 
basis being apparently geographical and without valid characters 
to distinguish the forms, viz.: H. tabernaculi from African (east 
coast and Mauritius); H. dugong from Indian (Malaysia and the 
southern shores of Asia to the Red Sea); and H. australis from 
Australian seas.

Introduction. —This species, which is nearly allied to the satin 
bower-bird, is especially interesting, as being the constructor of a 
bower even more extraordinary than that of the latter, in which the 
decorative propensity is carried to a far greater extent. From the 
extreme shyness of its disposition this bird is seldom seen by ordinary 
travellers, and it must be under very peculiar circumstances that it 
can be approached sufficiently close to observe its colours. Mr, 
Gould, being secluded near a small waterhole—a basin in a rock on 
a remote mountain, to which he had been guided by an aboriginal— 
during a dry season, writes of the result thus :--‘* My presence wag 
evidently regarded with suspicion by the visitants to the spot; but 
while I remained lying on the ground perfectly motionless, though 
close to the water, their thirst overpowering fear they would dash 
down past me and eagerly take their fill, although a black snake was 
lying coiled up on a piece of wood near the edge of the pool.” Six or 
eight spotted bower-birds displaying their beautiful necks were 
often perched within a few feet of him. ‘They were by far the 
shyest of the whole of the assemblage there congregated. Honey- 
suckers and parrots were constantly assembling throughout the day 
in this lonely spot, which presented no attractions to any person 
but a naturalist. Bath ahs
