I think you're right, McGraw. There seem to be a lot of names for a few kinds of drum.

I've found another instrument. Go to the painting (link in first post) and enlarge it as much as you can. Then locate:

right half of choir
second row from top
ninth angel from the center (in blue robe)

That angel is playing castenets.

(When counting the angels, disregard halos of angels not visible.)

That angel had probably been guarding pilgrims on the way to Santiago, where it acquired a fondness for Spanish music.
