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 Meliphagide 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 
Timaliide of the Indo-Malay islands, which are represented by
