除Barrtard& Barnard（1983）所述的海生钩虾外，本文还对钩虾总科、属的检索表、特征和种表进行了整理。这项工作是一本手册，通过使用人工（非系统发育）的关键字在家庭组的水平，导致附属关键字的家庭或家庭组的属的gammaridean端足类属的水平。多型科中的属被充分地诊断和描述以适合每个组内的分类学并发症。家系的诊断仅限于那些偏离伽马模型的性状，而伽马模型是用文字和插图来诊断的;因此，有些家系可能有相同的诊断。因此，与相似家族的交叉比较是每个诊断的有机组成部分。家庭描写扩大了家庭特征的共性。亲缘关系不是在系统发育水平上确定的，而是在确定时可能出现的混淆。读者必须交叉比较可能作为诊断的一部分提到的几个家族之间的关系，因为为了节省空间，所有可能的组合不会在每个可能的节点上复制。同样的比较方法通常但不限于用于每个科的属。为一些较困难的科提供了多个检索表;分类群经常被引用得比一个检索表多。一个家庭的图像钥匙的运作与同样的条件下，只有偏离模式伽马描绘。图形索引以相反的顺序排列，以便最不规则的分类群首先出现，而最接近模型诊断的分类群则放在最后。这一进展遵循的想法，最偏离类群是最容易确定的家庭。水平参考Barnard & Barnard（1983）的方法，建立了一个识别海洋伽马类所需的主检索表，并建立了两个检索表。在必要的地方，每个分类单元都提供了自1965年以来的迁移或重大变化的注释，这些注释尚未成为澳大利亚博物馆记录（1991年）补充13（第1部分）的共同知识，或者在此实施。每个属都提供了一个物种和选定的参考清单。在Bamard & Bamard（1983）的列表和地图中可以识别每个物种的地理代码。参考书目包括许多未在正文中引用的出版物，但省略了海洋伽马类，除了自1980年以来出版的项目，这些项目未包括在Bamard & Bamard（1983）中。有效使用本手册需要记忆伽马模型，按照此处提供的说明进行解剖的技能，熟悉术语表，并接受钥匙和诊断只是辅助手段而不是绝对终点的想法。
Keys, diagnoses and lists of species are presented for the marine families and genera of Gammaridea except those marinegammaroids treated by Barrtard& Barnard (1983). This work is a handbook for the identification of gammaridean amphipods to generic level through the use of artificial (non-phylogenetic) keys at the family-group level which lead to subsidiary keys to the genera of families or family groups. Genera in polytypic families are diagnosed and described sufficiently to fit the taxonomic complications within each group. Diagnoses of families are limited to those characters departing from a·gammaridean model which is diagnosed in words and illustrations; hence some families may have identical diagnoses. Therefore, cross-comparisons to similar families are made an organic part of each diagnosis. Family descriptions amplify the generalities of family characters. Relationships are identified not at phylogenetic level but in terms.of possible confusion in making identifications. The reader must cross-compare relationships among the several families that might be mentioned as part of the diagnoses because, to save space, all possible combinations are not replicated at every possible node. The same comparative method is generally but not exclusively used for the genera of each family. Multiple keys are provided for some of the more difficult families; taxa are often cited more tha, once in a key. A pictorial key to families operates with the same proviso that only the deviations from the model gammaridean are depicted. The pictorial key is arranged in reverse order so that the most anomalous taxa appear first and those closest to the model diagnosis are placed· at the end. This progression follows the idea that the most deviant taxa are the easiest to identify to family. level. The master key to families has the endpoints necessary to identify marine gammaroids by reference to Barnard & Barnard (1983); the two works are constructed .inparallel·fashion~·Families,andgenefawithin~families,areOfganisedalphabetically~ ·An index provides the principal reference for each genus and species. Where necessary, each taxon is supplied with notes on removals or major changes since 1965 which have not become common 2 Records of the Australian Museum (1991) Supplement 13 (Part 1) knowledge, or which are implemented herein. Each genus is supplied with a list of species and selected references. A geographic code, applied to each species, can be identified in the lists and maps of Bamard & Bamard (1983). A bibliography includes many publications not cited in the text but omits the marine gammaroids except for items published since 1980 which were not included in Bamard & Bamard (1983). Effective use of this handbook requires memorisation of a gammaridean model, skill in dissection following directions supplied herein, familiarity with the glossary, and acceptance of the idea that keys and diagnoses are only aids, not absolute endpoints.
