BANDURRIA, a Spanish musical instrument of the guitar family having from three to six strings plucked by a plectrum. The bandurria is not to be confused with the pandura, an ancient oriental instrument of the lute type, from which, as also from the mandoline, it differs essentially inasmuch as its back is flat, not vaulted. In England the bandurria, or a very similar instru ment, was known as a bandoer or bandora.
