Length of sagitta is greater than height; height/ length ratios from approximately 60–72%. Margins smooth except for few small lobes on posterodorsal and posteroventral. Anterodorsal margin nearly straight; remaining dorsal and posterodorsal margins rounded.Anteroventral margin only slightly rounded; middle portion of ventral margin almost horizontal. Posteroventral margin rounded. Anterior more tapered than posterior. Prominent sulcus on inner face slants at approximately 45-degrees. Sulcus extends across approximately 75% of inner face. Dorsal and ventral margins of sulcus essentially parallel. Sulcus undivided, no defined ostium and cauda. Ostium does not quite reach anterior margin. Short, fairly wide ostial channel opens onto anterodorsal margin. Posterior of sulcus rounded. No depressed area above sulcus. Crista superior more pronounced than crista inferior. No ventral furrow. Outer face usually convex, thickest at center.    Remarks   Gnathophis meridiesis an uncommon component at its typestratum and locality, the lower Eocene Bashi Formation (Wilcox Group) in Meridian, Mississippi. This taxon is also uncommon in the Claiborne Group in Alabama. Species of  Gnathophislack a depressed area above the sulcus, a feature that occurs on most congrid otoliths. Although one of the specimens we examined is a juvenile and two specimens are fairly worn, they possess the salient characteristics indicative of  Gnathophis meridies.   Stratigraphic and geographic range in Alabama   Gnathophis meridiesis known only from the “upper” LisbonFormation at site ACh-7.
