We search for the decays B- --> l(-)<(nu)over bar>(l) in a sample of 2.2 x 10(6) charged B decays using the CLEO detector. We see no evidence for a signal in any channel and set upper limits on the branching fractions of B(B- --> tau(-)<(nu)over bar>(tau)) < 2.2 x 10(-3), B(B- --> mu(-)<(nu)over bar>(mu)) < 2.1 X 10(-5), and B(B- --> e(-)<(nu)over bar>(e)) < 1.5 x 10(-5) at the 90% confidence level.
