In Paleontology of Ohio, Vol, ii, p. 337, Meek mentions a similar Schizodus from the Upper Coal Measures of Nebraska, but thinks it is probably a distinct species, on account of the small size, more nearly central beaks and more prominent central and anterior margins. The specimen from Arkansas really agrees better with this description than it does with the undoubted Schizodus cuneatus, but the Nebraska specimen was never figured and named. Schizodus cuneatus was also found in the Lower Coal Measures of Conway county. 8 N., 17 W.. section 33, northeast quarter of northeast quarter. Schizodus wheeleri Swallow, Pl. xxii, Fig. 4. Cypricardia (?) wheeleri Swallow, Trans. St. Louis Acad. Sci., Vol. i, p. 96. Schizodus wheeleri Swallow, F. B. Meek, Final Rept. IT. S. Geol. Survey Nebraska, p. 209. This species is very common in the Coal Measures from Pennsylvania to New Mexico, in both Upper and Lower Coal Measures. It has been figured and described so often that nothing new can be added. Our specimens agree best with those from Iowa, described by F. B. Meek, Final Report of the U. S. Geological Survey Nebraska, p. 209, Pl. x, Fig. 1, c. Occurrence.--Several specimens, both rightand left valves, were found in the Lower Coal Measures of Conway county, 8 N., 17 W., section 33, northeast quarter of northeast quarter, at Cook's stone quarry, near Hattieville. This horizon is in the so-called Millstone Grit, and near the middle of the Lower Coal Measures. All the fossils in these strata are preserved i...
