Figure 1 Entire specimen of the massive coral, Pavona gigantea Verrill, showing two of the crescent-shaped burrows from which Pseudocryptochirus crabs were extracted. The larger of these, presumably occupied by a female crab, is the one sketched in Figure 2 with crab in situ. versity of California, Berkeley. Standing 15 cm high and measuring cm in greatest diameter and cm in circumference, it retains within its base a portion of the granite rock to which it was united before it was detached from the substrate. Widely spaced around its periphery, and in such a manner that only two, or at the most three, are visible in any one camera angle, are crescent-shaped burrows of the following dimensions in mm: Height Width Depth (Occupant) (ov 5 ) (ov?) —- (in situ) (ov?) {$) (non-ov ? ). 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 Southern California Academy of Sciences.
