In 1994, and 1996-1998, the Nightingale reverse was modified slightly. Instead of the Croatian 'Slavuj' the bird's name is replaced with the Latin Lusciannia megarhynchos. Except they spelled the first part incorrectly: it should read Lusciania megarhynchos.
The obverse still bears the marten, whose pelt was once a monetary unit, and whose Croatian name -- Kuna -- is still the monetary unit.
