Abstract: The cohomology of modular varieties defined by congruence subgroups of $ {\operatorname{Sp} _4}({\mathbf{Z}})$ whose levels lie between $ 2$ and $ 4$ is studied. Using a counting argument and the techniques of zeta functions, the authors completely determine the cohomology of a particular variety of this type.
