"In the monography recent system of baikalian amphipods is critically examined, its revision at a level of families will be carried out. A few genera of amphipods with a various lifestyle (Pallasea, Acanthogammarus, Parapallasea, Ommatogammarus) are also reconsidered. The special attention is given to the systematics of a parasitic genus Pachyschesis, with the description 12 species new for the science; their lifestyle and parasit-hosts specifity are characterized; general laws, connected with the transition of crustacean to the parasitism, are considered. The basic trends of an endemic evolution of the baikalian fauna of amphipods, evolutionary parallels between amphipods of Baikal and marine basins are described. The complete list of valid families, genera and species of baikalian Amphipoda is given."
