The study is of the marine gastropods in the Cerithiopsidae and Newtoniellidae collected from expeditions to New Caledonia and the Loyalty Islands. In all 171 species were found among which 76 are newly described as well as an additional 3 species that are figured but not named. Most of the shells are small in these groups and the size ranges from about 14mm. to less than 2mm. in length. While these shells are not the kind of shells that are of interest to most shell collectors, the authors of this study have done a remarkable job in making their research available for scientific workers to study.The small size of the shells poses no obstacle to the very precise and very clear photographs that are found in this journal. The authors have given special attention to the protoconchs of these shells as a key in their separation into species. As for general shell collectors, this can serve as a study that will open your eyes to the structural beauty and diversity found in even the smallest of molluscan shells.
