The difference between the two extremes is so marked that, but for the possession of a fairly well-graded series, it might fairly have been regarded as specific. The inside of the dry corallum is, like the soft tissues of the polyp, of a dark madder-colour. 2. Flahelhun laciniatum^ Philippl.

A single specimen, in very fair preservation, from Station 116, 405 fathoms, which we name with some confidence from Philippi's description. We are not able, however, to identify it with Prof. Martin Duncan's figures, which appear to represent young and there- fore not unequivocally determinable forms of Flahellum laciniatum, Phil., natural size. We agree with Prof. Moseley (' Challenger ' Deep-sea Madreporaria, p. 170) in considering that his Flabcllum ala-.
