Abstract
THE group of sea spiders, or the Pycnogonidea, was for a long time among the least known, though by no means the least interesting, of the divisions of the marine invertebrates. Linnæus described a species as a Phalangium, placing it among terrestrial forms, and though a century and a quarter has passed since then, the problem of where to place these Pycnogonids cannot be said to be finally settled.
