Challenger During the Years 1873-76 The Opportunities of examining the Hydroida in a living state, or even in dead speci mens which have the soft parts sufficiently well preserved, are so comparatively few, that the systematist is compelled to have recourse to the chitinous periderm, as affording almost the only available grounds for determination and classification. This chitinous external skeleton, however, presents so many points of high morpho logical interest, that the classification thus based upon it is by no means an arbitrary and artificial one.
