|dc.description.abstract||A detailed account of the anatomy of Pachycormus macropterus (Blainville)
1818, the type species of the type genus of the family Pacbycormidae is
given, with special reference to the neurocranium, visceral arch skeleton
and pectoral girdle.
The genera and species ascribed to the family Pachycormidae by various
authors are reviewed with the result that: - three genera, Leedsichthys
(Woodward) 1889, Eugnathides Gregory, 1923, and Ohmdenia Hauff 1953, are
removed; three other genera, Asthenocormus (Wagner) 1863, Prosauropsis
Sauvage 1895, and Orthocormus Weitzel, 1930 are found to be ill founded
and their species redistributed within the family; and the number of species
in several of the remaining genera is reduced.
A revised diagnosis of the family is given and a list of characters drawn
up, on the basis of which the Pachycormidae sensu stricto is considered
to be monophyletic; the interrelationships of the genera within the family
are considered. Finally the relationships of the pachycormids to other
major groups of fishes are reviewed and a new systematic position assigned||en_US
