Nice, but this begs the question: why don't you simply make up your own? I guess there's not much wrong with using existing weapon animation slots, but I can feel the trouble brewing.

Adds casting animations for mummies, mindflayers, cornugons, glabrezu, tattered skeleton warriors, and yuan-ti spellcasters
Mummies: Nice.
Mind Flayers: I may be mistaken, but these look identical to the animations already included (the mind flayers have G25 and G26, and they appear valid to me).
Cornugon: This may be a problem with ToB on Mac OS X, or a problem with 3D, but the animation is too wide (whenever the wings are full-span, the cornugon starts floating around on the screen and parts of the interface get drawn around it).
Glabrezu: Nice.
Tattered Skeleton: Nice.
Yuan-Ti: Nice.
EDIT: I should mention that I tested each sequence for all of these, using CTRL+S and CTRL+A. I also checked weapon animations for various weapon styles (these shouldn't make a difference, since there are no weapon animations for these creatures). Everything (minus the cornugon) worked properly.
You also include the whole IC_LIZARD_CASTER1 animation set, but quite a few of these are unnecessary (they're identical to the animations already included in BG2).
I would have liked to see a refined wailing virgin (if such a thing exists; the one in BG2 doesn't have a death animation and has the shortened casting animation). Oh well.
