The monographic description of Permian cephalopods of Primorye region has been
 made in the first time (24 nautiloid and ammonoid forms including 5 new species were
 described); some -ammonoid beds were distinguished within Chandalazian and Ludjan-
 zian formations of Permian; the correlation of Permian sediments of different region
 was accomplished; on the basic of data on ammonoids of Pamirs, Sicily, Primorye
 region and Trans-Caucasus the preliminary scheme of  zonal stratification of Permian
 within Tethys is proposed.
