[D&D] Alternate Monster Names

An often-overlooked section of the AD&D Monster Manual II is its index, which includes not only its own contents but also those of the original Monster Manual and the Fiend Folio, and also lists various alternative names for monsters from all three volumes in addition to the standard names. This is interesting to me, because while some of those names are included in the monster names or descriptions, many of them are not - particularly for the Fiend Folio creatures, which it almost seems as if Gary Gygax or someone else at TSR systemically renamed, perhaps as a memory aid.

Because I think some of these alternate names are fun and in a few cases like them better than the standard ones (and especially like the world-building flavor of different people having different names for the same thing) and because while the index references the standard name for each alternative name but doesn't do the reverse, I decided it was a worthwhile exercise to go through the index to compile all of the alternate names and arrange them by the order of the books for easy reference. So now I can see at a glance that stirges are also called bat birds, ettercaps are sometimes known as spider-beasts, khargra are earth fish, osquips are rock rats, and so on. And, having done that work, I figured other people might also be able to get some use out of it, so I might as well share it.
