Так я достал такую классификацию:
1) Stone trolls
2) Cave trolls
3) Hill trolls
Цитата:
A variety of troll adapted for life among hills and moorland. Aragorn's grandfather Arador was slain by them in the hills north of Rivendell, and a company of these creatures were among the armies that Sauron loosed from the Morannon in the War of the Ring.
In appearance they were man-like, but larger, and seem to have been covered with hard scales. They were fearsome and vicious, bellowing like beasts as they stormed into battle, and beating their enemies down with great hammers.
4) Mountain trolls
Цитата:
Apparently trolls that lived in the mountains of Middle-earth. It was creatures of this kind that wielded the great battering-ram, Grond, at the Battle of the Pelennor.
5) Olog-hai
6) Snow trolls - ?
Цитата:
Trolls adapted for life among snow and ice. No snow-troll appears in Tolkien's work, but we can infer their existence from the fact that Helm Hammerhand is compared to one of these creatures during his sorties against the Dunlendings during the Long Winter
P.S. sorry за то, что по-английски. Переводить лень.
