Abstract
This Ganoid appears to have been first described, under the name of
Squalus spatula
, by Maduit in the ‘Journal de Physique’ for 1774, pp. 384-386, plate 2, fig. 1. Sub sequently, several zoologists described and figured the external appearance of
Polyodon
under the various synonyms of
Polyodon
(Lacépéde),
Spatularia reticulata
(Shaw), and
Planirostra
(Lesueur). The systematic position of the genus appears to have changed as often as its name. Originally regarded as an Elasmobranch, and subsequently as a Teleostean, it was reserved for H. Müller, in 1846, to elucidate its real affinities and to indicate its marked distinctness from the other families of Ganoids by establishing the suborder Chondrostei for its reception.
