Scientific paper

New infrared (JHK) observations of 38 early-type galaxies with dust-lanes have been obtained. About one third of these have red broad-band colours when compared with a sample of 19 morphologically normal galaxies. IR excesses are found preferentially in systems exhibiting at least weak signs of a luminous disc. Eleven of the galaxies have published radio continuum fluxes or upper limits. Within this small subset there is no indication of a correlation between infrared excess and radio flux density. Two of the galaxies with infrared excesses lie within X-ray error boxes from HEAO-A2 observations.
