  The recent discovery of isotopes with Z=110--111 suggests evidence for (1) a
monopole--monopole interaction that does not appear explicitly in
Nilsson--Strutinsky mass systematics, and (2) a competition between $SU(2)$ and
$SU(3)$ dynamical symmetries that has been predicted for this region. Our
calculations suggest that these new isotopes are near spherical, and may
represent a true island of superheavy nuclei, but shifted downward in neutron
number by these new physical effects.
