Snow-trolls were one of several troll subspecies.
Snow-trolls are mentioned only once in Tolkien's works, in reference to Helm Hammerhand stalking his enemies "like a snow troll" during his sorties against the Dunlendings in the Long Winter. The trolls who lived in the Coldfells in western Eriador may have been similar to these.
