1996年查戈斯考察队收集了128个后鳃腹足类标本，代表至少50个物种，其中只有41个物种在本文中描述：两个cephalaspideans都属于Chelidonura属，两个sacoglosan种Thuridilla，一个有问题的分类海兔，和36种裸鳃类。在裸鳃亚目中，除了海蛞蝓，所有的亚目都只有一个或两个物种，而海蛞蝓则占了大部分。其中2个种仅被分配到属中，Phyllidiopsis和Dermatobranchus各1个种，而2个种与已知种相似。本文报道了多个Phyllidiidae种，但只有10个种被确定为一个分类单元，并对Hoplodoris pustulata、Dendrodoris tuberculosa、Phyllidiopsis xishaensis和Phyllidiella striata的分类地位进行了讨论。在印度洋有四个新的分布记录，有几个物种是有趣的，因为它们很少被记录。
The 1996 Chagos expedition collected 128 specimens of opisthobranch gastropods representing at least 50 species, of which only 41 species are described in this paper: two cephalaspideans both belonging to the genus Chelidonura, two sacoglossan species of Thuridilla, one sea hare with problematic taxonomy, and 36 species of nudibranchs. Of the nudibranchs, all the sub-orders are represented by one or two species only except the dorids, which comprise the majority of the collection. Two species are allocated to genus only, one species each of Phyllidiopsis and Dermatobranchus, while two species are similar to known species. Numerous species of Phyllidiidae were collected, but only 10 are confidently assigned to a taxon. The taxonomic identities of Hoplodoris pustulata, Dendrodoris tuberculosa, Phyllidiopsis xishaensis and Phyllidiella striata are defined and discussed. There are four new distribution records for the Indian Ocean and several species are of interest as they have been rarely recorded.
