An analysis is presented of events with a single jet and significant missing transverse energy selected from 4.7 pb[sup [minus]1] of data collected at the Fermilab Tevatron with the CDF detector. The goal is to identify events of the type p[anti p] [r arrow] Z[sup 0] + jet; Z[sup 0] [r arrow] [upsilon][anti [upsilon]]. Event selection and backgrounds are discussed. The number of observed monojet events is compared to the number of observed Z[sup 0] [r arrow] e[sup +]e[sup [minus]] events in which the Z[sup 0] is accompanied by a jet. The author measures the number of light neutrino species to be N[sub [upsilon]] = 2.2[+-]1.5 and then places an upper limit on the number of neutrino species at N[sub [upsilon]] < 5 (90% C.L.).
