The engraved gem which forms the subject of this note (plate I, Al, A2, and fig. 1) is part of the collection of Mr. Richard Falkiner of London. I am grateful to him for allowing me to publish it here, and for placing at my disposal the notes which result from his own inquiries. What is known of the history and provenance of the object may be stated in a few words. It was bought by its present owner from a London dealer who had obtained it at auction.
