Camera lucida drawing of holotype, YPM 8932 from Yale P4 excavation in Wayne, New Jersey. Scale = 1 cm. For abbreviations, see legend for Fig. 25. group (Olsen and McCune ms). The pattern of the snout is Uke that described for the S. elegans group (Olsen and McCune ms). The circumorbital series is complete and composed of 2 or 3, usually 3, su- praorbitals (which may or may not be tuberculated), the dermosphenotic, 5 or 6 infraorbitals, the lachrymal, and 2 infraorbitals between the lachrymal and the antorbital. The infraorbitals within the circumorbital ring seem to be slightly thinner than in the S. elegans group, but the lachrymal and anterior infraorbitals are similarly deep. The dermopterotic and the pattern of the lateral line canals are like those of the S. elegans group. Like other non-Lepidotes semionotids, including the S. elegans group, Semwnotus capensis (Olsen and McCune ms), S. normanniae, and S. bergeri (McCune 1982), the cheek region is completely open except for an oval suborbital positioned between the circumorbitals and preoperculum and below the dermopterotic. The jaw joint is like that described by Patterson (1973) for L. toombsi, and all other Newark semionotids (Olsen and McCune ms), S. normanniae, S. bergeri (McCune 1982). The palate, the hyoid arch, the opercular series, and the pectoral girdle show no deviation from the pattern seen in the S. elegans group. I have seen very little of the gill arches, braincase, and other endoskeleton and will not attempt to describe Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Peabody Museum of Natural History.
