. A brief general account of fossil fishes : the Triassic fishes of New Jersey. Fishes, Fossil; Paleontology. THE STATE GEOLOGIST. 85. Fig. 12. Semionotus fultus Ag. Fulcra and anterior rays of dorsal fin As already remarked, the sole criterion relied upon by New- berry for distinguishing the so-called S. meter opt erus consisted in a supposed relatively greater depth of body—"the fusiform and slender fish standing for /. fultus, and the broader one for /. ; Curiously enough, it has been shown by Dr. Eaton, after a study of Newberry's originals in the American Museum of Natural History, that whereas one of the specimens of S. macropterus in its compressed and flattened condition is deeper than a type of S. fultus, all the others are proportionately more J. H. Redfield, after advocating the suppression of the name "macropterus," remarks that S. fultus is specially characterized by the length of the dorsal and anal fins, which are even longer than in S. tenuiceps. 2 A comparison of text Fig- ures 12 and 13 will enable one to appreciate the differences as regards structure of the dorsal fin in this species and S. microp- terus. In Plate IX. of this report is given a photographic repro- duction of one of Newberry's originals. This is the most abundant of all the New Jersey species, and in the Connecticut Valley Trias is only inferior numerically to the ubiquitous S. tenuiceps. The average length is stated by New- 1Amer.
