UC San Diego Library – Scripps Digital Collection

Although the collections of NAGA Expedition are small and contain many well-known and widely distributed species of the Indo-West Pacific area, they also contain several little-known forms (e.g. Charybdis edwardsi Leene and Buitendijk, Portunus minutus [Shen] and P. tweediei [Shen]) and two new species. A few additional Indo-West Pacific Specimens from the collections of the Scripps Institution, other than NAGA material, are included in the present report. With the better-known species the synonymy has been abbreviated to one or two recent references which permit ready identification; in other cases a full synonymy is given. NAGA collections are reported in the text as Station Numbers (followed by NAGA Catalogue Numbers) with detailed localities and their lists of species in the Appendix. These localities are also plotted on the map. Measurements are of total breadths, including last anterolateral teeth; those over 100 mm to the nearest 0.5 mm, and the remainder to the nearest 0.1 mm.
