The logic MSOL+$\mathbb{B}$ is defined, by extending monadic second-order logic on the infinite binary tree with a new bounding quantifier$\mathbb{B}$. In this logic, a formula $\mathbb{B}$X. φ(X) states that there is a finite bound on the size of sets satisfying φ(X). Satisfiability is proved decidable for two fragments of MSOL+$\mathbb{B}$: formulas of the form $\neg\mathbb{B}$X.φ(X), with φ a $\mathbb{B}$-free formula; and formulas built from $\mathbb{B}$-free formulas by nesting $\mathbb{B}$, ∃, ∨ and ∧.
