Fehse, D. presents significant contributions to the knowledge of the Triviidae family, detailing new species discovered across various regions in the Pacific. The findings include new taxa from the Tonga Islands, Fiji, Society Islands, Tuamotu Archipelago, Solomon Islands, Vanuatu, Lifou, and New Caledonia, as well as insights on Dolin's work regarding Indo-Pacific Triviidae. Notable new species identified are Gregoia peregrina, Gregoia tonga, Gregoia eua, and Trivellona carina, among others. The research introduces a variety of new taxa, such as Gregoia alta, Trivellona plana, and Trivirostra angustata, expanding the understanding of this diverse family. Additional species include Purpurcapsula pulcherrima, Gregoia ramosa, and Trivellona inflata, highlighting the rich biodiversity within these regions. The annotation emphasizes the breadth of new discoveries, which contribute to the ongoing study of marine mollusks and their classification. Overall, the work underscores the importance of continued exploration and documentation of marine life in the Pacific.

All known fossil and Recent species of the endemic South African genus Triviella Jousseaume, 1884 are critically revised. The type material of many species is presented on photos for the first time, and many of the often short original descriptions were emendated when necessary. All available information are summarized and aspects of the zoogeography are explained. Five new species are described as Triviella lorenzi n. sp., Triviella chiapponii n. sp., Triviella montorum n. sp., Triviella carptima n. sp., and Triviella martybealsi n. sp.

This comprehensive study on Triviidae builds upon Cate's 1979 review, introducing two new genera and numerous species from the central Indo-Pacific, Pacific, and southwestern Indian Ocean that are new to science. Most of the new taxa originate from deep-sea environments, reaching depths of up to 1000 meters. The work is divided into several parts, detailing new Triviidae from various regions, including the Philippines, Taiwan, Indonesia, and the Australes, as well as the Marquesas. Among the new taxa are Gregoia n. gen. and Novatrivia n. gen., along with multiple new species such as Gregoia mauricettae, Gregoia albengai, and Gregoia mariecatherinae, among others. The study also presents species like Novatrivia mirabilis and Trivellona gilbertoi, contributing significantly to the understanding of this family. This volume not only expands the taxonomic framework of Triviidae but also enhances knowledge of their distribution and ecological significance in deep-sea habitats.
