of getting a shot at it. Mr. Roe, the Sur veyor-general, who examined several mounds during his expedition to the 
interior in the year 1836, found the eggs nearly ready to hatch in the month of November, and invariably seven or 
eight in number; while another authority has informed me of an instance of fourteen heme taken from one 
mound.” 
In a subsequent letter Mr, Gilbert states that the flavour of the egg is very similar to that of the Tortoise or

Turtle, and that when mixed with tea its similarity to the peculiar roughness and carthy flavour of that of the 
Hawk’s-bill Turtle is very remarkable. 
Genus Mrcaropius, Quay §& Gain. 
The members of this genus imhabit all the Indian and Philippine Islands and Australia, Mr. G, R. Gray 
informs me that “ the females of some species associate together in bands during the night and deposit their eggs 
in a cavity which they dig to the depth of two or three feet ; that the successive deposits of eggs amount to a 
hundred or more aud are left to be hatched by the solar rays; that some cover them with sand and others with 
the remains of plants; and that the eggs are extremely large for the size of the birds, and are generally of 
a cinnamon colour.” 
442. Megapodius tumulus, Gould. ; > : : : : ‘ R ; ‘ Kubo Va Bh ze. 
The following interesting account of the breeding-places of this remarkable bird has been transmitted to me by 
Mr. John M‘Gillivray as the result of his observations on Nogo or Megapodius Island in Endeavour Straits. It 
will be seen that its range is more extensive than I had assigned to it :— 
“The most southern locality known to me for this singular bird is Haggerston Island (in lat, 12° 3! south), 
where I observed several of its mounds of very large size, but did not see any of the birds. During the survey of 
Endeavour Straits in H.M.S. Bramble, I was more fortunate, having succeeded in procuring both male and female 
on the island marked *‘ Nogo’ upon the chart, where I resided for several days for that sole purpose. On this small 
island, not more than half a mile im length, rising at one extremity into a low rounded hill densely covered with 
jungle (or what in New South Wales would be ealled ‘ brush’), three mounds, one of them apparently deserted 
before completion, were found, The two others were examined by Mr. Jukes and myself. The most recent, 
judging from the smoothness of its sides and the want of vegetable matter, was situated upon the crest of the hill, 
and measured 8 feet in height (or 13} from the base of the slope to the summit) and 77 feet in cireumference. In 
this mound, after several hours’ hard digging into a well-packed mass of earth, stones, decaying branches and 
leaves and other vegetable matter, and the living roots of trees, we found numerous fragments of eggs, besides one 
broken egg containing a dead and putrid chick, and another whole one, which proved to be addled. All were 
imbedded at a depth of six feet from the nearest part of the surface, at which place the heat produced by the 
fermentation of the mass was considerable. The egg, 3+ by 2% inches, was dirty brown, covered with a kind of 
epidermis, which easily chipped off, exposing a pure white surface beneath. Another mound, situated at the foot 
of the hill close to the beach, measured no less than 150 feet in circumference, and to form this immense 
accumulation of materials the ground in the vicinity had been scraped quite bare by the birds, and numerous 
shallow excavations pointed out whence the materials had been derived, Its form was an irregular oval, the 
flattened summit not being central as in the first instance, but situated nearer the larger end, which was elevated 
14 feet from the ground, the slope measuring in various directions 18, 214, and 24 feet. At Port Lihou, im a small 
bay a few miles to the westward, at Cape York and at Port Essington, I found other mounds which were 
comparatively low, and appeared to have been dug into by the natives. The great size the tumuli (which are 
probably the work of several generations) have attained on Haggerston and Nogo patie arises sci Sees from 
those places being seldom visited by the Aborigines, I found several eves of large size in the ovarium of a EPRIAI 
shot in August, while the condition of the oviduct showed that an egg had very recently passed; hence it is 
probable that, in spite of their great comparative size, one bird lays several ; but whether cach mound is resorted 
to by more than one pair, I had not the means of ascertaining.
