"BaLTOBERGSTROEMIa" SULCATA (BeRGSTROM I973) Holmia sulcata; Bergstrom 1973:292, figs. 7, 8; Ahlberg et al. 1986:41, fig. 41. Types: Holotype, Palaeontological Institute, University of Lund, Lund, Sweden (PIL), LO 4462T, see Bergstrom (1973). Discussion: The generic name of this species is placed within paraphyletic shuttermarks be- cause it differs from the type of the genus in the condition of only one character, part of the reason why the two species were placed within the same genus: the condition of the poste- rior margin of the ocular lobe relative to the junction of the posterior margin of the lobe with the glabella. In B. mobergi the posterior margin of the lobe is rotated outward about 10 degrees relative to its condition in "; sulcata. This species is excluded from the genus Holmia because of the condition of characters 1 to 3, 5 and 6, listed above under B. mobergi. Occurrence: Sweden: Believed to be in the Holmia kjerulfi zone, from ForsemoUa in An- drarum and Brantevik-Gislovshammar, eastern 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.
