To avoid undue repetition of references in the text of the follow- ing descriptions, all the terms used are those discussed and defined in previous works (Maderson, 1965a, 1966b, 1967; Maderson and Licht, 1967). This nomenclature is shown in schematic form in Figure 1. Condition One (6 specimens); PI. 1, figs. 2-4. Plate 1, figure 2 shows a sagittal section through a scale taken from the anterior margin of the specialized abdominal region where the gland development is smallest; an enlarged portion of the low- power view is shown in Plate 2, figure 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.
