Ursus in 370-390, which had a nave and four aisles, was destroyed in 1734-44, only the (inaccessible) crypt and the round campanile remaining from the earlier structure; there are fragments of reliefs from a pulpit erected by Archbishop Agnellus (556-569) in the interior.
The more important of the carnivores which haunt the forests, valleys and mountain slopes are the bear (Ursus arctos), wolf, lynx, wild cat and fox (Vulpes melanotus).
In 1893 the bones of a cave-bear (Ursus spelaeus) were taken from a cavern of the Bjelasnica range, in Herzegovina, a discovery without parallel in the Balkan Peninsula.
Three species of bears are scientifically recognized, but one of them, the ice-bear (Ursus maritimus), is only an accidental visitor, carried down by the Arctic current.
Louisiana bears (Ursus luteolus) still inhabit the inaccessible canebrakes near the coast, and occasionally one is found farther west; and in the western mountains black (and cinnamon) bears, including the New Mexico black bear (Ursus Americanus amblyceps) still are found.
