HE Island of Palawan, Palauan, or Paragua is situated some 90 miles to the north of Borneo. Geographically speaking, Palawan belongs to the Philippine group, being, like those islands, of later volcanic origin. Its fauna, however, has been received from both Borneo and the Philippines, and the greater proportion of its zoological productions have undoubtedly been received from the first-named island. This has been carefully demonstrated by Mr. A. H. Everett, in a paper read before the Zoological Society (April, 1889). Thus we may conclude with a fair degree of certainty that Palawan has been, at some time or other during the world's history, joined to Borneo and perhaps also to the Philippines, and for a considerably longer period formed part of the great island of Borneo.
Palawan is about 275 miles long, the breadth varying from 6 to 26 miles. To the north it is connected with the Philippines by a collection of islandsathe Calamianes. To the south the islands of Balabac, Ballimbangan, and Banguey may be mentioned as the connecting-links with Borneo. The depth of the sea at the southern end is only 100 fathoms, while at the northern extremity a deep channel of 722 fathoms divides Palawan from the Philippines.
The coasts are dangerous to navigators, being a network of coral reefs, over which the sea often breaks. These reefs rise like walls from the bottom of the sea, deep channels often running in close to the shore.
Through the centre of Palawan run ranges of volcanic mountains, none of which, however, are active. The alluvial washings from these mountains have formed extensive plains on the southern coast ; but the plains are not so great on the opposite side, where the mountains at times rise from the sea-coast : this is to be accounted for by the violence of the China Sea, which breaks with full force on this coast.
