根据文献数据和我从沿海收集的大量材料，概述了挪威水域已知的带壳海洋底栖腹足类动物的分布。覆盖的地理区域在大陆斜坡上向下延伸约1200米，从南部的瑞典边境延伸到东北部的俄罗斯边境。在斜坡上，分布仅限于0°以东和72°n以南的地区，北海和挪威海沟的西部“斜坡”都不包括在内。系统学和命名学密切遵循克莱门（欧洲海洋软体动物检查表）。重点是每个物种在指定区域内的分布，但在认为相关的地方也讨论了分类学和命名学问题。总共包括365个物种级别的分类群，其中326个被认为绝对属于挪威的动物群。其余的被记录为可疑的，要么因为只发现了空壳，要么它们的确认分布超出了这里定义的限制。在所包括的“物种”中，我认为至少有18种未被描述，而另外16种是在Hoisaeter（1986）出版后从挪威材料中描述的。47种的北部分布界限被扩大，11种的南部分布界限被扩大。66种的属名与Hoisaeter（1986）中使用的属名不同，而35种有另一个特定的名称。本文的主要部分列出了所有更改，并提供了对更改源的参考。鉴定出4种区系成分：坡面成分，主要分布于500 ~ 1200 m负温度的大陆坡面；一种北极成分，挪威的物种几乎只在东芬兰马克发现；挪威的一组物种，只在或主要在斯卡格拉克海岸或奥斯陆峡湾发现；最后是在大部分海岸发现的主要群体。
Based on literature data and my extensive material from along the coast, the distribution of shell bearing marine, benthic gastropods known from Norwegian waters, is outlined. The geographic area covered goes down to c. 1200 m on the continental slope, and extends from the Swedish border in the south to the Russian border in the north-east. On the slope the distribution is restricted to an area east of 0°, and south of 72° N. Neither the North Sea nor the western ‘slope’ of the Norwegian Trench are included. Systematics and nomenclature follow Clemam (Check List of European Marine Mollusca) closely. The emphasis is on the distribution of each species within the designated area, but taxonomic and nomenclaturial problems are discussed wherever considered relevant. Altogether 365 species level taxa are included, of which 326 are considered as definitely belonging to the Norwegian fauna. The rest are recorded as doubtful, either because only empty shells have been found, or their confirmed distribution falls outside the limits here defined. Of the ‘species’ included, I consider at least 18 to be undescribed, while another 16 were described from Norwegian material after Hoisaeter (1986) was published. The northern distributional limit is extended for 47 species, while 11 species have received a new southern limit. Sixty six species have a generic name diferent from the one used in Hoisaeter (1986), while 35 species have another specific name. All changes are listed in the main part of the article, and references are given to the sources for the changes. Four faunal components are recognized: a slope component, species mainly found in negative temperatures on the continental slope, between 500 and 1200 m; an Arctic component, species in Norway almost exclusively found in East Finnmark; a group of species in Norway found only or mainly on the Skagerrak coast or in Oslofjorden; and finally the main group found along most of the coast.
