«Kola Meridian» is a standard hydrobiological transect in the Barents Sea lo-cated along 3330' E. Regular hydrological and hydrobiological studies at the transect have been carried out since late 19th century. However, almost all results of these stud-ies remain unpublished and majority of the collected materials are lost. We tried to find remaining samples of gastropods in the collections of the Zoological Institute of RAS. Only 151 lot from 65 samples, collected from 1898 to 1991 had been found. Revealed species composition differ from previously published data.
