These fishes are much more specialized than are the Ceratodontidae; the body is more or less eel-shaped, the scales are thinner, the paired fins are reduced to slender styliform appendages formed of a jointed axis with or without a unilateral fringe of cartilaginous rays bearing fine dermal rays, and the lung is paired.
This view was based mainly on the assumption that the skull was autostylic and that maxillary bones were not developed, and also on the resemblance, previously noticed by J. Newberry, between the dentition of Dinichihys and that of Protopterus.
Woodwards proposal has not met with general acceptance, but it is strongly supported by the recent investigations of C. Eastman, who has added fresh arguments in favor of the autostylic condition of the skull and the homology of the cranial roof-plates with those of the Dipnoans, the Ceratodontidae in particular.
