  We calculate the superconformal indices of recently discovered
three-dimensional N=4,5 Chern-Simons-matter theories and compare them with the
corresponding indices of supergravity on AdS4 times orbifolds of S7. We find
perfect agreement in the large N and large k limit, provided that the twisted
sector contributions at the fixed loci of the orbifolds are properly taken into
account. We also discuss the index for the so-called "dual ABJM" proposal.
