The first gave the most generally useful results for this study. COMPARATIVE MORPHOLOGY OF THE REPRODUCTIVE ORGANS In common with all known isopods the body of Limnoria can be divided into three major regions (Fig. 1) : the cephalon or head bearing the eyes, antennae, and mouth parts; the peraeon peraeon pleon cephalon (head). pleotelson ( telson) antennae brood pouch with eggs 5th peroeopod pleopods (leg) Fig. 1. Gravid female Limnoria (from G. O. Sars, 1897). Major regions of the body mentioned in text are noted. (The assistance of Mr. Robert Winsett, Scientific Illustrator, Publications Division, , in the final preparation of Figures 1, 2, 5, 6 is particularly appreciated.) or thorax bearing usually seven pairs of walking legs; and the pleon or abdomen bearing usually five pairs of swimming and respiratory appendages, the pleopods. The male and female gonads are contained within the peraeon. Their relationship to other major organs is shown in Figure 2. In Limnoria the sexes are separate but this is not true for several other isopods (p. 372). The body of an adult Limnoria tripunctata is roughly mm. long and mm. wide at the 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 Har
