At p. 286 three species of Physeter are mentioned under Aleut names, and at p. 288 six species of Balaena. These are cited by Chamisso (Nov. Act. Acad. Leop.-Carol. Nat. Curios., xii, 1, 1824, pp. 249-260), who refers to volume and page of Pallas's work, showing that this portion of the work, at least, was accessible to Chamisso as early as 1824, although not commonly recognized as "published" till 1831. On this point see Coues, Birds Col. Valley, 1878, p. 615.
