  We present Berkeley Illinois Maryland Association (BIMA) millimeter
interferometer observations of giant molecular clouds (GMCs) along a spiral arm
in M31. The observations consist of a survey using the compact configuration of
the interferometer and follow-up, higher-resolution observations on a subset of
the detections in the survey. The data are processed using an analysis
algorithm designed to extract GMCs and correct their derived properties for
observational biases thereby facilitating comparison with Milky Way data. The
algorithm identifies 67 GMCs of which 19 have sufficient signal-to-noise to
accurately measure their properties. The GMCs in this portion of M31 are
indistinguishable from those found in the Milky Way, having a similar size-line
width relationship and distribution of virial parameters, confirming the
results of previous, smaller studies. The velocity gradients and angular
momenta of the GMCs are comparable to the values measured in M33 and the Milky
Way; and, in all cases, are below expected values based on the local galactic
shear. The studied region of M31 has a similar interstellar radiation field,
metallicity, Toomre Q parameter, and midplane volume density as the inner Milky
Way, so the similarity of GMC populations between the two systems is not
surprising.
