根据雌性生殖器官的结构，可以将腕足动物的6个超科分为两类。在Gymno胸膜和Dromiacea中，输卵管在第三准足类动物的髋部打开，精囊是胸骨的内翻，与输卵管没有任何内部联系；在这些方面，它们类似于非短肢动物的十足动物，它们的受精也是外部的，这两个超级科可以统称为原始短肢动物。在其余四种中，即长尾、短尾、短尾和短尾，雌性生殖器开口在第6胸骨上，精囊是输卵管的扩大部分。它们有内部受精，在这方面在Deca poda中可能是独一无二的，并且将被称为高级Brachyura。在一篇较早的论文（Hartnoll, 1968a）中，我描述了晚期短尾目雌性动物生殖道的形态，并证明了它们在结构上有相当大的差异，尤其是阴道和外阴。同时，我对在螃蟹身上观察到的不同形式的交配行为产生了兴趣，因为这些行为可能与结构变化有关。因此，我收集了有关交配行为的信息，部分来自原始研究，但大部分来自迄今为止在文献中非常分散的已发表数据。事实上，在女性生殖器的结构和交配方式之间只发现了有限的相关性，这方面将在本文的最后一节中讨论。关于交配的积累数据在论文的正文中进行了介绍和讨论，并得出了一些结论。在这个过程中，有必要反复提到某些物种和关于它们的各种信息来源。为了避免不必要的重复，在表1中按科列出了物种和参考文献的完整编号表。在文本中，在适当的地方列出了这些编号表，以表明某一节所依据的数据。甲壳纲动物，16岁
It is possible to divide the six superfamilies of the Brachyura into two groups on the basis of the structure of the female reproductive organs. In the Gymno pleura and the Dromiacea the oviducts open on the coxae of the third peraeopods, and the spermathecae are invaginations of the sternum without any internal connection with the oviducts; in these respects they resemble the non-brachyuran Decapoda, in which fertilisation is also external, and the two superfamilies may collectively be termed the primitive Brachyura. In the remaining four, the Cory stoidea, Oxystomata, Brachyrhyncha and Oxyrhyncha, the female genital openings are on the sixth thoracic sternite, and the spermathecae are enlargements of the oviducts. They have internal fertilisation, being probably unique among the Deca poda in this respect, and will be referred to as the advanced Brachyura. In an earlier paper (Hartnoll, 1968a) I described the morphology of the genital ducts in females of the advanced Brachyura, and demonstrated that there was considerable variation in structure, especially of the vagina and vulva. At the same time I became interested in the different forms of mating behaviour observed in crabs, in view of the possibility that these might be related to the structural variations. Accordingly I collected information on mating behaviour, in part by original research, but largely from published data which were hitherto very widely scattered in the literature. In fact only a limited correlation was found between the structure of the female genitalia and the manner of mating, and this aspect is covered in the final section of the paper. The accumulated data on mating are presented in the body of the paper, discussed, and a number of conclusions drawn. In the course of this account it is necessary to make repeated references to certain species and to the various sources of information regarding them. In order to avoid unnecessary repetition a complete numbered list of species and references is given, family by family, in table I. In the text lists of these numbers are given where appropriate to indicate the data upon which a particular section is based. Crustaceana, 16 11
