  Very recently, it was pointed out that there exists a population of gamma-ray
sources without associations at other wavelengths which exhibit spectral
features consistent with mono-energetic lines at energies of approximately 111
and 129 GeV. Given recent evidence of similar gamma-ray lines from the Inner
Galaxy, it is tempting to interpret these unassociated sources as nearby dark
matter subhalos, powered by ongoing annihilations. In this paper, we study the
spectrum, luminosity, and angular distribution of these sources, with the
intention of testing the hypothesis that they are, in fact, dark matter
subhalos. We find that of the 12 sources containing at least one prospective
line photon, only 2 exhibit an overall gamma-ray spectrum which is consistent
with that predicted from dark matter annihilations (2FGL J2351.6-7558 and 2FGL
J0555.9-4348). After discounting the 10 clearly non-dark matter sources, the
statistical significance of the remaining two prospective line photons is
negligible. That being said, we cannot rule out the possibility that either or
both of these sources are dark matter subhalos; their overall luminosity and
galactic latitude distribution are not inconsistent with a dark matter origin.
