We report here additional positive results of a search for muonless neutrino- and anti-neutrino-induced events using an enriched antineutrino beam and a muon identifier of relatively high geometric detection efficiency. The ratio of muonless to muon event rates is observed to be R=0. 200. 05. We observe no background derived from ordinary neutrino or antineutrino interactions that is capable of explaining the muonless signal.
