Extract

In a paper by Mr E. W. Binney on the Fossil Fishes of the Pendleton Coal Field, published in 1841, the dentary bone of Rhizodopsis is figured as the “upper jaw of a new species of Holoptychius,” to which, however, he did not attach any specific name. In the same paper its scales are also figured and referred to the same genus. Scales belonging to the same fish were afterwards figured by Professor Williamson under the name of Holoptychius sauroides, and again by Mr Salter, as those of Rhizodus granulatus. Both of these specific names occur under Holoptychius in Agassiz's general list of Ganoids published in 1843, but as they were unaccompanied either by figures or descriptions, it is really immaterial which of them, if indeed either, was applied by him to the fish in question. The authority for the term “sauroides” as applied to the common species of Rhizodopsis, the only species of the genus which is as yet known with certainty, must therefore remain with Professor Williamson. Holoptychius sauroides of Binney and of Messrs Kirkby and Atthey is quite another fish, now also distinguished generically as Strepsodus, and for it the specific name “sauroides” is therefore equally valid.
