1. MM对Zoantharia的令人钦佩的分类。米尔恩·爱德华兹和朱尔斯·海姆虽然非常精心和自然，但在通用继承的连续性中提出了几个非常明确的“突破”。 Turbinoliæ 和 Astroœidæ 两个重要科之间的巨大区别使得分类比实际情况更加人为。乍一看，这种分类似乎不太实用，因为有几个属要么根本无法放置，要么被暂时安排在某些科或科中。本次交流的目的是描述将 Turbinolidæ 科与 Astroœidæ 结合在一起的属的物种，描述一些非常奇特的 Heterophylliæ 和 Battersbyiæ 并对它们进行分类，并将 Palœcyclus 属从 Fungidæ 科中删除到 Cyathophyllidæ 科中。
1. The admirable classification of the Zoantharia by MM. Milne-Edwards and Jules Haime, although very elaborate and natural, presents several very decided “breaks” in the continuity of the generic succession. The great distinction between the important families of the Turbinoliæ and Astrœidæ renders the classification rather more artificial than it really is; and at first sight this classification may appear not very practical, on account of there being several genera which either cannot be placed at all or are arranged provisionally amongst certain divisions or families. The objects of this communication are to describe the species of a genus which unites the family of the Turbinolidæ to that of the Astrœidæ, to describe some very peculiar Heterophylliæ and Battersbyiæ and to classify them, and to remove the genus Palœcyclus from the family of the Fungidæ into that of the Cyathophyllidæ.
