We investigate observational constraints from lensing statistics and high-z type Ia supernovae on flat cosmological models with nonrelativistic matter and an exotic fluid with an equation of state, pₓ=(m/3-1)ρₓ. We show that agreement with both tests at the 68% confidence level is possible if the parameter m is low (m0.85) and 0.24Ωₘ₀0.38 with lower values of Ωₘ₀ corresponding to higher m. We find that a conventional cosmological constant model with Ωₘ₀0.33 is the best fit model of the combined likelihood.
