A description of the Crangonidae shrimp collection is presented. It was collected by Dr. K. Sakai from catches of fishing vessels operating on the shelf and the upper part of the continental slope of Tosa Bay (Shikoku Island, Japan) in 1961-1962, 1979 and mainly in 1963. Then this collection was transferred for storage to the Crustacean Section of the Zenkenberg Research Institute (Frankfurt am Main, Germany). During processing this collection of shrimps, they were measured with an accuracy of 1 mm from the end of the rostrum to the end of the telson (total length - TL) and (or) from the end of the rostrum to the middle of the dorsal part of the posterior edge of the carapace (length of the carapace - CL). The collection included 64 specimens of crangonid shrimp, including: 5 females Aegeon lacazei (Gourret, 1887); 1 female, 2 males and 4 damaged specimens Neocrangon sagamiensis (Balss, 1913); 1 female, 2 males and 4 damaged specimens Crangon dalli Rathbun, 1902; 4 females and 7 males Parapontocaris aspera Chace, 1984; 1 female Parapontocaris laevigata Chace, 1984; 12 females of Metacrangon longirostris (Yokoya, 1933); 19 females and 2 males of Pontocaris pennata Bate, 1888. For the first time, three species of crangonids (N. sagamiensis, P. aspera, P. laevigata) were discovered in the Tosa Bay. In the description of each species, in addition to length measurement data and sex determination, if necessary, the justification of the taxonomic status of the species is given, as well as information about the presence or absence of eggs on the pleopods of females.
