Note 15 — Class—CRUSTACEA. Sub-Class—CIRRIPEDIA.

The protrusion of the egg-bearing pouches in Cyclops and its kindred genera, outside the body, offers a feeble analogy with what takes place in Cirripedes. Professor Allman (‘Annals of Natural History,’ vol. xx, p. 7,) who has attended to the subject, says that the external egg-bearing pouches are “a portion of the membrane of the true ovaries:” if the membrane of these pouches had been specially made adhesive, the analogy would have been closer.
