   I think the second sentence below needs to have the phrase “torsion-free” added to it twice. Right? I’m going to do that.

   a) The category $\lambda Ring$ of $\lambda$-rings is monadic and comonadic over the category of $C Ring$ of commutative rings.

   b) The category $\lambda Ring_{\neg tor}$ of $\lambda$-rings is monadic and comonadic over the category of $C Ring_{\neg tor}$ of commutative rings.
