This illustration does not convey quite adequately the effective way in which the pit is filled up by its inhabitant. B. C. dimorphus (after Henderson). Female and male, X8, to show the striking sexual dimorph- ism in this species. Compare with figures D and F of C. coralliodytes, where the male and female are drawn to the same scale and are more nearly the same size. C-F refer to C. coralliodytes. C. Side view of mature female, X6. The eggs in the brood pouch are indicated as seen through the transparent lateral walls of the latter. Note also the flattened anterior part of the carapace, and the enlarged second pair of thoracic appendages used in movement in the pit. D. Ventral view of mature female, X6. Some of the developing eggs in the brood pouch are seen projecting from it. The immature eggs in the ovary are indicated by the dotted circles in the abdomen, posteriorly. E. Immature female, ventral view. To show narrow abdomen. F. Male, X6, to show size compared to mature female. The copulatory styles are represented by dotted lines passing beneath the abdomen, emerging at its anterior 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 Carnegie Institution of Washington.
