. The microscope and its revelations. on , iii the last few yearspublished several interesting papers. CIRBIPEDIA 967 really so abrupt as it might at first sight appear to the group ofCirripedia, consisting of the barnacles and their allies ; for these,like many of the Suctoria, are fixed to one spot during the adultportion of their lives, but come into the world in a condition thatbears a strong resemblance to the early state of many otherCrustacea. The departure from the ordinary crustacean type inthe adults is, in fact, so great that it is not surprising that zoolo-gists in general should have ranked them in a distinct class, theirsuperficial resemblance to the Mollusca, indeed, having caused mostsystematists to place them in that series, until due weight wasgiven to those structural features which mark their articulatedcharacter. We must limit ourselves, in our notice of this group,to that very remarkable part of their history, the microscopicstudy of which has contributed most essentially to the elucidation.
