Abstract：
A catalogue is presented of the nematode slide collection of W.L. Nicholas, which is deposited in the National Research Collections Australia at CSIRO. This is the most extensive slide collection of free-living marine and estuarine nematodes from Australia to date, and consists of 553 putative species, collected across a wide range of Australias eastern and northern regions over the course of nearly 40 years. The collection contains mostly marine and estuarine free-living nematodes collected on coarse substrate in littoral habitats. The most abundant genera were Desmodora, Theristus, and Onyx. Most taxa were found rarely, being recorded only once, and repeated sampling at several sandy beach sites revealed only a small proportion of the fauna on more than one occasion. A significant proportion of the taxa were also found to be widespread, occurring on more than one occasion at more than one location, with Theristus sp., Onyx sp., and Viscosia sp. occurring in the greatest number of localities. The catalogue adds an additional 90 species and 160 genera to the documented fauna of Australian free-living nematodes verifiable by specimens in permanent collections. It thus provides a better framework for studying nematode biodiversity and biogeography in the region.
摘要：
列出了W.L.Nicholas的线虫幻灯片集合的目录，它存放在CSIRO的澳大利亚国家研究收藏中。这是迄今为止澳大利亚最广泛的自由生活海洋和河口线虫的幻灯片集合，由553个推定物种组成，在近40年的时间里，收集了澳大利亚东部和北部的广泛地区。该集合主要包含在沿海栖息地的粗糙基质上收集的海洋和河口自由生活线虫。最丰富的属是Desmodora,Theristus,还有Onyx.大多数分类群很少被发现，只被记录一次，在几个沙滩上反复取样，不止一次发现只有一小部分动物区系。也发现了很大一部分分类单元，在一个以上的地点发生在一个以上的场合，Theristussp.,Onyxsp.,和Viscosiasp.发生在最多的地方。该目录为记录的澳大利亚自由生活线虫动物区系增加了90种和160属，可通过永久收藏中的标本进行验证。因此，它为研究该地区的线虫生物多样性和生物地理学提供了更好的框架。
