430 ZOOLOGICAL GEOGRAPHY. [part III.very much richer in <strong>the</strong> one case than in <strong>the</strong> o<strong>the</strong>r. <strong>The</strong> 24o-enera derived from Borneo and Java are only about one fourth<strong>of</strong> <strong>the</strong> characteristic genera <strong>of</strong> those islands; while <strong>the</strong> 15Moluccan and Timorese geuera are fully one third <strong>of</strong> <strong>the</strong>ircharacteristic types. <strong>The</strong> proportion derived from <strong>the</strong> Australian,is greater than that derived from <strong>the</strong> Oriental side.We shall exhibit this perhaps more clearly, by giving a list <strong>of</strong><strong>the</strong> important groups <strong>of</strong> each set <strong>of</strong> islands which are absentfrom Celebes.Important Families <strong>of</strong> Java and Borneoabsent from Celebes.Important Families <strong>of</strong> <strong>the</strong> Moluccasabsent from Celebes.1.

Thismay be balanced by <strong>the</strong> absence <strong>of</strong> <strong>the</strong> excessively abundantTimaliidffi <strong>of</strong> <strong>the</strong> Indo-Malay islands, which arerepresented by
