This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Panes (Greek)
Panes were rustic spirits (daimones) of the mountains and highland pastures who protected the goat herds and sheep flocks which grazed these lands. Panes were depicted as goat-footed men with the horns, tail, beard, snub nose and ears of a goat. They sometimes had actual goat-heads instead of just a few goatish features.
