Collected by A. S. Rogovich

• ZIN PH

•Probably, after Rogovich’s death his collection was divided into several parts and transferred to dif- ferent institutions of Moscow, Saint Petersburg, and Kiev (Fig. 2). In Moscow, Rogovich’s collection first appeared in the Geological Room (Cabinet) of the Imperial Moscow University (GR; Pavlova 1910; mammals), later A.P. and M.V. Pavlovs Geological- Paleontological Museum, primarily within the Moscow Geological Prospecting Institute (MGRI; 1930–1987), and now within the Vernadsky State Geological Museum (SGM; for detailed history of SGM see Bessudnova 2006). In the unknown period, one turtle specimen from Rogovich’s collection (ZIN PH 8/36) was transferred from MGRI to ZIN, as is documented by a label written by L.I. Khosatzky, which is accompanying the specimen (Fig. 1E). Some fishes from the Rogovich’s collection are stored in SGM (Nessov 1992), although Bannikov (2010) not- ed that their storage is unknown. In 2017, one of us (IGD) during a visit to SGM managed to find two pe- ripheral plates of a pancheloniid sea turtle in one box with Rogovich’s material of fishes and mollusks from the Zaitsev’s brickworks of Kiev (these specimens are not included in the description). The presence of Rogovich’s mammals in SGM needs verification
