Thaumastocheles zaleucus (Astacura). A blind deep sea decapod, from a depth of over 800 metres off the West Indies. Actual length of body about 10 cm. (After Spence-Bate). Too little is known about the distribution of the deep-water Crustacea to make any definite assertions. It seems probable that most of the abyssal genera are cosmopolitan where the oceans are deep enough, but the species are more restricted in their distribu- 1 Since this account was written both amphipods and isopods have been recorded from 10,687 metres in the Tonga 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 Green, J.
