are in most; cases very great, and are much more conspicuous in the specimens themselves 
than on paper. It will be seen that no less than fourteen Papilionidæ inhabiting Celebes 
and the Moluccas are from one-third to one-half greater in extent of wing than the allied 
species representing them in Java, Sumatra, and Borneo. Six species inhabiting Amboyna 
are larger than the closely allied forms of the northern Moluecas and New Guinea by about 
one-sixth. These include almost every case in which closely allied species can be compared.

The differences of form are equally clear. 
Papilio Pammon everywhere on the continent is tailed in both sexes. In Java, Sumatra, 
and Borneo, the closely allied P. Theseus has a very short tail, or tooth only, in the male, 
while in the females the tail is retained. Further east, in Celebes and the South Moluccas, 
the hardly separable P. Alphenor has quite lost the tail in the male, while the female 
retains it, but in a narrower and less spatulate form. A little further, in Gilolo, P. Nicanor - 
has completely lost the tail in both sexes. 
Papilio Agamemnon exhibits a somewhat similar series of changes. In India it is 
always tailed ; in the greater part of the archipelago it has a very short tail; while far 
east, in New Guinea and the adjacent islands, the tail has almost entirely disappeared.
