Croats seemingly were not recorded by the Bavarian Geographer (9th century), however, some scholars assumed that the unknown "Sittici" ("a region with many peoples and heavily fortified cities") and "Stadici" ("an infinite population with 516 gords") were part of the Carpathian Croats tribal polity, or that the Croats were part of these unknown tribal designations in Prykarpattia. Others saw "Lendizi" (98), "Vuislane", "Sleenzane" (50), "Fraganeo" (40; Prague), "Lupiglaa" (30 gords), "Opolini" (20), and "Golensizi" (5) as possible tribes of Croats. Lehr-Spławiński, Łowmiański and others concluded that Vistulans and Lendians because of their mention and described location in different sources were tribes behind which were hidden Croats.
