erous on the north-western coast.

The specimens from Goulburn Islands consist of reddish sandstone, not to
be distinguished from that which occurs beneath the coal formation in
England. On the west of these islands the coast is more broken, and the
outline is irregular: but the elevation is inconsiderable; the general
height in Cobourg Peninsula not being above one hundred and fifty feet
above the sea, and that of the hills not more than from three to four
hundred feet.

On this part of the coast, several hills are remarkable for the flatness
of their tops; and the general outline of many of the islands, as seen on
the horizon, is very striking and peculiar. Thus Mount Bedwell and Mount
Roe, on the south of Cobourg Peninsula; Luxmoore Head, at the west end of
Melville Island; the Barthelemy Hills, south of Cape Ford; Mount Goodwin,
south of Port Keats; Mount Cockburn, and several of the hills adjacent to
Cambridge Gulf, the names given to which during the progress of the
survey sufficiently indicate their form, as House-roofed, Bastion,
Flat-top, and Square-top Hills; Mount Casuarina, about forty miles
north-west of Cambridge Gulf; a hill near Cape Voltaire; Steep-Head, Port
Warrender; and several of the islands off that port, York Sound, and
Prince Regent's River; Cape Cuvier, about latitude 24 degrees; and, still
further south, the whole of Moresby's flat-topped Range, are all
distinguished by their linear and nearly horizontal outlines: and except
in a few instances, as Mount Cockburn, Steep-Head, Mounts Trafalgar and
Waterloo (which look more like hills of floetz-trap) they have very much
the aspect of the summits in the coal formation.*

(*Footnote. Captain King, however, has informed me, that in some of these
cases, the shape of the hill is really that of a roof, or hayrick; the
transverse section being angular, and the horizontal top an edge.)

Sketch 1 of some of the islands off Admiralty Gulf (looking southward
from the north-east end of Cassini Island, about latitude 13 degrees 50
minutes, East longitude 125 degrees 50 minutes) has some resemblance to
one of the views in Peron's Atlas (plate 6 figure 7): and the outline of
the Iles Forbin (plate 8 figure 5, of the same series) also exhibits
remarkably the peculiar form represented in several of Captain King's
drawings (Sketch 2).

The red colour of the cliffs on the north-west and west coasts, is also
an appearance which is frequently noticed on the sketc
