parison of the short- with the long-ranged species are expressed in 
the following table.

This shows 1) that, considering the probable error of such small 
numbers, the short- and the long-ranged species contribute about 
equal proportious to the cold fauna; 2) that very few of the tem- 
perate group are short-ranged, exactly the reverse of the behaviour of 
the tropical groups. - 
Further, 
of 44 “Hot” species 38 are short-ranged and only 6 are long-ranged, 
0 BA 
of 13 or 18 “cold” species 8 or 11 are short-ranged whilst 5 or 
7 are long-ranged — 39 9); 
of 35 or 40 “Temperate” species 6 or 9 are short- but 29 or 
31 are long-ranged — 80 |,. 
But if we take all the species promiscuously, which oceur in 
the Hot zone, these amount to about 60, about two-thirds of the 
whole number available, and in them the long- and the short-ranged 
species are equally represented! This contradietory result is a strong 
indication that the dwellers in the tropical Hot-lands are a compound 
assembly of at least two categories, namely Natives, some of which 
may ascend ever so far beyond their original hot clime, secondly 
immigrant descendants from temperate parts, ‘be these the plateau 
or more Northern regions. 
The “Southern” Genera and Species. 
(Total 44 species. Diagram No. II, and List A.) 
Of these Southerners 35 species occur within the first 1000 feet 
from sealevel, and thence they extend upwards as follows.
