Glossaulax hicolor (Ph'iW'p'pl 1848) (Text-fig. ), living in the Holoccne warm waters of Japan, is similar to end form A (Tcxt-ftg. ) of (i. didyma didyma, but the former species is easily distinguished from the latter because: (1) the anterior callus lobe of the um-. 14b ^-*=^' 3" ^^ 10b Text-figure 22 -Glossaulax didvma didvma (Roding, 1798) from Paleo-Ofuna Bay (Matsushima and Ohshima, 1974). All the specimens illustrated (xQ 8) are preserved m KPM (unnumbered). The specimens of la-2b. 3a-6b, 7a-10b, and 1 la-14b were collected, respectively, from localities 1 (loc. 8 of Matsushima, 1984), 2 (loc. 9 of Matsushima. 1984). 3 (loc. 16 of Matsushima, 1984), and 4 (loc. 34 of Matsushima, 1984) illustrated in this 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 Paleontological Research Institution (Ithaca, N.
