Loren Coleman from Cryptomundo has added to his list of the top 13 most credible cryptids and now has a list of the top 50 cryptids from around the world.

Certainly worth a read over, as most people have probably never even heard of most of them. Another good source of info on the subject is the Leaves of Wisdom information source at Book of THoTH. There's a cryptids page there that has a fairly extensive list.
