al rare and new crustacea--Squilla, Lupea thalamita, and a new
genus allied to Gonoplax, which will be found described in the Appendix.
Of landshells, only two kinds, a Helix and a Succinea, were found upon
Facing Island. Of marine species, 41 were added to the collection; the
most important in a non-zoological point of view is a kind of rock oyster
of delicious flavour and large size.

LEAVE PORT CURTIS FOR THE NORTHWARD.

November 29th.

Sailed from Port Curtis for the northward, in company with the Asp, the
Bramble being sent to Moreton Bay in order to communicate the results of
the survey to the Colonial Government, and rejoin us at Cape Upstart. For
the next two days light northerly winds prevailed, after which we had the
wind from about East-South-East.

PERCY ISLES.

December 3rd.

The Asp having made a signal for assistance, and it being ascertained
that she had lost her dinghy and bumpkin by a sea which struck her while
crossing a tide-race, it was judged necessary to run for the nearest
place where the damage could be repaired. We consequently anchored under
Number 2 of the Percy Isles, to leeward of its south-west point, in 10
fathoms, mud, between it and the Pine Islets of the chart.

Here it blew so hard from East-South-East that a second anchor was let
go; the yards were pointed to the wind, and the top-gallant masts sent on
deck. A party which attempted to land were forced to return, nor was it
thought expedient to repeat the attempt on the following day. We remained
at this anchorage until the 7th, and found the gale to subside into the
south-east trade.

This is the largest of the Percy Isles, being about twelve or fourteen
miles in circumference. In structure, it may be said to consist of a
series of hills running in ridges, many of them covered with gumtree
scrub; and all with long grass growing in tufts, concealing the loose
stones, and rendering walking very laborious. On the western side of the
island, about a mile from the anchorage, the sea communicates, by a
narrow entrance, with a large basin partially blocked up with mangroves,
among which a creek filled at high-water, runs up for a mile. At the head
of this hollow a deeply worn dried up watercourse indicated the
periodical abundance of fresh water; and by tracing it up about a mile
further, I found many large pools among the rocks containing a sufficient
supply for the ship, but unavailable to us in consequence of the
difficulty in
