. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. Fig. 5. Anacontium carpenteri Raymond, x 4. Fig. 6. Anacontium brevis Raymond, x 4. show no furrows. The eyes are small, well forward and far apart, so that the cardiopthalmic area occupies a large portion of the prosoma. The genal spines are minute, and probably would not be seen on poorly preserved specimens. The posterior margin of the prosoma is turned down vertically, as in modern Limulus. Measurements. The holotype (prosoma) is 7 mm. long, 12 mm. wide; the width between the eyes is mm. and the posterior end
. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. Fig. 5. Anacontium carpenteri Raymond, x 4. Fig. 6. Anacontium brevis Raymond, x 4. show no furrows. The eyes are small, well forward and far apart, so that the cardiopthalmic area occupies a large portion of the prosoma. The genal spines are minute, and probably would not be seen on poorly preserved specimens. The posterior margin of the prosoma is turned down vertically, as in modern Limulus. Measurements. The holotype (prosoma) is 7 mm. long, 12 mm. wide; the width between the eyes is mm. and the posterior ends of the opthalmic ridges are mm. apart. The cardiac lobe is mm. long, and 3 mm. wide at the posterior end. The cardiopthalmic area is 5 mm. long, on the median line. The paratype (prosoma) is 5 mm. long, about 9 mm. wide and the width between the eyes is mm. Formation and locality. Two specimens of the prosoma were collected from the Wellington formation on the southwest quarter of the north- west quarter of section 2 of township 21 north, range 1 west, in Noble County, Oklahoma, where they were associated with numerous speci- mens of Conchostraca and insects. The holotype is 4724, and the paratype 4725. It is named for Professor F. M. Carpenter who found the specimens, and whose studies and collections have greatly enlarged our knowledge of Permian arthropodan 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 Harvard University.
