very much richer in the one case than in the other. The 24 

 genera derived from Borneo and Java are only about one fourth 

 of the characteristic genera of those islands; while the 15 

 Moluccan and Timorese genera are fully one third of their 

 characteristic types. The proportion derived from the Australian, 

 is greater than that derived from the Oriental side. 



We shall exhibit this perhaps more clearly, by giving a list of 

 the important groups of each set of islands which are absent 

 from Celebes.

If we reckon the absent families to be each represented by 

 only two important genera, we shall find the deficiency on the 

 Oriental side much the greatest ; yet those on the side of the 

 Moluccas are sufficiently remarkable. The Meliphagidse are not 

 indeed absolutely wanting, since a Myzomela has now been 

 found in Celebes ; but all its larger and more powerful forms 

 which range over almost the entire region, are absent. This 

 may be balanced by the absence of the excessively abundant 

 Timaliidse of the Indo-Malay islands, which are represented by
