Eight gastropod species, rare in the Tshegan Formation, are considered. These species and six families, which include these species, were only mentioned in faunal lists of this formation (Amitrov, 1994, 2005). Two new species, Periaulax tsheganica sp. nov. (Trochidae) and Pusillina kazakhstanica sp. nov. (Rissoidae), are described. Other six species of the families Diastomatidae, Marginellidae, Melanellidae, and Mathildidae are figured and compared with related species; their distribution is discussed.
