The exceeding richness of the Malayan region in these fine insécts is seen by com- 
paring the number of species found in the different tropical regions of the earth. From 
all Africa only 33 species of Papilio are known; but as several "e still undescribed 
in collections, we may raise their number to about 40. In all tropical Asia there are at 
present described only 65 species, and I have seen in collections but two or three which 
have not yet been named. In South America, south of Panama, there are 120 species, 
or about the same number as I make in the Malayan region; but the area of the two 
countries is very different ; for while South America (even excluding Patagonia) contains 
5,000,000 square miles, a line encircling the whole of the Malayan islands would only 
include an area of 2,700,000 square miles, of which the land-area would bé about 
1,000,000 square miles. This superior richness is partly real and partly apparent. The 
breaking up of a district into small isolated portions, as in an archipelago, seems m 
favourable to the segregation and perpetuation of local peculiarities in Miro. p so
