No, it is Bidleid. Shalba probably hadn't even been born at that point in time. He is not mentioned once in this story (at least yet, anyways). The point is that we were being introduced to the original Four Great Maous' children and establishing their characters. Even if they were way older and in places of responsibility, they obviously never matured and act like spoiled children, who were arrogant because of their lineage.
