We study the cohomology of the massless BRST complex of the Type IIB purespinor superstring in flat space. In particular, we find that the cohomology atthe ghost number three is nontrivial and transforms in the same representationof the supersymmetry algebra as the solutions of the linearized classicalsupergravity equations. Modulo some finite dimensional spaces, the ghost numberthree cohomology is the same as the ghost number two cohomology. We alsocomment on the difference between the naive and semi-relative cohomology, andthe role of b-ghost.
