We have presented 
CCD photometry of a 0.06 square degree
near the nominal core of the open cluster, IC 2391. This data has been used
to prepare (V,B-V) and (R,R-I) colour-magnitude diagrams. Superimposing
theoretical isochrones appropriate to the age of IC 2391, we have
identified 17 stars as candidate cluster members possessing colours and
magnitudes corresponding to spectral types 
. We have compared this
number to the number of Pleiads that would be expected to be found in the
same area of sky and deduce that, if the luminosity function and space
distribution is similar to that of IC 2391, the contamination of our
photometric candidate membership list by background objects should be small.
