VIII.] SUB-REGIONS. 295 



St Julian Island in the Tambelan Archipelago, and being drawn 

 south of the Great Natuna (Bungoran Island), passes northward of 

 Labuan and thence follows the loo-fathom line, so as to embrace 

 Balabac, Palawan (Paragua), the Calamianes, and the Cuyo 

 Islands, and, returning along the same line of soundings on the 

 southern side of Palawan, is drawn immediately to the islands of 

 Cagayan Sulu, and Sibutu, whence it is continued through the 

 Makassar Straits south of the Paternoster, Lauriot (Laset Ketjil), 

 and Solombo islets, and in a north-westerly direction through the 

 Karimata Strait back to the island of St Julian." In the following 

 list the genera and species peculiar to the group are printed in
