contents We extend the Otal-Rosas bound on the number of small eigenvalues of the Laplacian on a hyperbolic surface to the small eigenvalues of pseudo-Laplacians. In the process, we extend the work of Colin de Verdière on the spectral theory of pseudo-Laplacians to hyperbolic surfaces with more than one cusp.
