APPENDIX. 
A. At eleven miles from the entrance, the port is separated into 
Sect. IV. . . 
—1. two inlets, which wind under the base of a dividing range 
of high, steep, and wooded hills ; these run up for five miles 
higher, when they become mere mangrove creeks. There is 
probably another inlet on the east side of Port Warrender 
which we did not examine, since it appeared to be less con- 
siderable in size, and important in appearance, than the arm 
which we had examined. Crystal Head is in latitude 
14° 28', and longitude 125° 55' 30". 
WALMESLY BAY appeared to be a good port also, but 
it is open to the eastward. We did not enter it. 
CAPE VOLTAIRE is the extremity of a promontory, ex- 
tending for more than twenty miles into the sea, and sepa- 
rating the Admiralty Gulf from Montagu Sound. There is a 
flat-topped hill near its extremity, in latitude 14° 14' 30", 
and longitude 125° 40' 12"; and, at three miles more to 
the southward, a peaked hill ; its shores on either side 
are rocky, and indented by bays. At one part the width 
across to Walmesly Bay cannot be more than a mile and a 
half. 
The MONTALIVET ISLES, about six leagues from the 
main, consist of three rocky islands ; they are visible for six 
or seven leagues from the deck : the north-easternmost is in 
latitude 14° 13' 40", longitude 125° 19' 30". 
MONTAGU SOUND extends from Cape Voltaire to the 
north end of Bigge’s Island, a distance of thirty-one miles, 
and is from eleven to twenty miles deep. It is fronted by a 
range of islands; the outer range, which is eight miles 
within the Montalivet Isles, was called Prudhoe Islands;
