This paper gives the logical basis for the prover Otter-lambda. At the time I did not realize that AC is inconsistent with lambda logic, which makes one theorem vacuously true and leaves a gap in the proof of the completeness theorem for lambda logic. These defects are repaired in the revised version; but the published version is also given here for reference. The revised version also includes the proofs omitted from the published version because of conference proceedings length limits.
