Clariﬁcation of data on ﬁndings of rare species of bivalve mollusks Acharax johnsoni (Dall, 1891) (Solemyidae)and <i>Conchocele bisecta </i>(Conrad, 1849) (Thyasiridae) in the Far Eastern seas of Russia
Data on ﬁnding of living specimens of two rare species of bivalve mollusks Acharax johnsoni (Dall, 1891) (Solemyidae) and Conchocele bisecta (Conrad, 1849) (Thyasiridae) in Bering Sea, described in the book by S.V. Yavnov «Atlas of Bivalve Mollusks of the Far Eastern Seas of Russia» [2016], is reliable for the ﬁrst species, but erroneous for the second one. A specimen of C. bisecta was collected in the Sea of Okhotsk instead. The collecting sites of these mollusks are speciﬁed. The ﬁnding of a living specimen ofA. johnsoni in the Bering Sea is the second one in history of the study of this basin.
