Lowland ’’ are those inland ^^arts not much ele¬ 
vated above the sea level, 
“Subalpine” includes the lower ranges of hills 
and country adjacent; and 
“ Alpine/’ the hills above (say) 2000 feet. 
We find, therefore, that the eight districts arrange 
themselves thus — 
1. Alpine and Subalpine—Kannoch, Athole, Bread- 
albane, and Lomond, 
2. Alpine, Subalpine, Lowland, and Littoral—Earn, 
Forth, and Perth, 
■3. Subalpine, Lowland, and Littoral—Gowrie. 
In ma^ng up lists of the productions of the whole 
oounty, it will be suflficient to merely indicate by 
means of the initial letters, the districts in which the 
species has been detected, and to note whether the 
species is Alpine, Subalpine, Lowland, or Littoral, 
whether it is common or rare, and to give in the 
latter case one or two habitats ; but in making up 
the species of a district it will be better to particu¬ 
larise in what part of the district the species is found 
or is most common. For this purpose, those districts 
which admit of it have been subdivided. These 
subdivisions with their characters, are :— 
1. Bannoch, into (a.) Bannoch
