  The results of magnetic susceptibility, electrical resistivity ($\rho$),
heat-capacity (C) and thermopower (S) measurements on CeCuAs2, forming in
ZrCuSi2-type tetragonal structure, are reported. Our investigations reveal that
Ce is trivalent and there is no clear evidence for long range magnetic ordering
down to 45 mK. The $\rho$ behavior is notable in the sense that (i) the
temperature (T)-coefficient of $\rho$ is negative in the entire range of
measurement (45 mK to 300 K) with large values of $\rho$, while S behavior is
typical of metallic Kondo lattices, and (ii) $\rho$ is proportional to T-0.6 at
low temperatures, without any influence on the exponent by the application of a
magnetic field, which does not seem to classify this compound into
hither-to-known non-Fermi liquid (NFL) systems. In contrast to the logarithmic
increase known for NFL systems, C/T measured down to 0.5 K exhibits a fall
below 2 K. The observed properties of this compound are unusual among Ce
systems.
