The beast, traditionally referred to as a kylin, is in fact a direct copy of a Japanese chimaere, or Kaitsu on a Japanese original. A similar plate is illustrated in Meissener Porzellan des 18. Jahrhunderts aus Bad Pyrmonter Privatbesitz Museum im Schloss Bad Pyrmont November 2002 - January 2003 Exhibition Catalogue (2002), p. 85, and another is illustrated by D. Hoffmeister, Katalog der Sammlung Hoffmeister (Hamburg, 1999), Vol. I, no. 186. Another example from the Dr. Sali Guggenheim Collection was sold by Christie's Geneva on 15th May 1995, lot 76.
