| A. S. Woodward 1895 | Based on a very well-preserved specimen from Eichstädt, presented on a double plate, from the former ducal Leuchtenberg collection, I have established this species, which It is closely related to both Oph. serrata and Oph. attenuata. However, it differs from both in that its width decreases only very gradually towards the rear, with the dorsal line sloping almost straight down, whereas in the former it is bulbous in the anterior part; furthermore, it differs from Oph. serrata in that it is narrower and more elongated, and from Oph. attenuata in that the body does not narrow abruptly, but decreases in width very gradually. It also shares with both species the characteristic that the scales, when well preserved, also show a finely toothed posterior margin. — The dorsal fin has been preserved along its entire length, but not along its full height. The short, thick skull shows that not only the premaxilla, but also the upper jaw, along with the lower jaw, is equipped with a row of small, pointed teeth... The entire length to the middle of the caudal sac is 7', the greatest body width 1" 8; the length of the dorsal fin, on which one counts about 30 rays, 2" 7'''. |
