It always protects itself by means of a living sponge (sometimes a compound ascidian) held over its back by the posterior two pairs of legs. The carapace is about as long as broad.

The carpus has three conspicuous distal tuberculiform teeth. The lateral teeth of the carapace are conspicuous, the two anterior ones the larger and less acute; on the left side the 2d tooth is double. The preorbital and suborbital teeth are about as larsfe as 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
