COMMENTS

Desmarest (1817) described Limulus walchii , a new limulid from the Jurassic of Solnhofen (Bavaria, Germany). In his famous monograph with A. Brongniart, Desmarest (1822) made the same description. Then numerous authors, ignoring the first Desmarest’s work, used this taxon with the date of 1822. The correct combination is thus Mesolimulus walchii ( Desmarest, 1817) .
