C-12O(2-1) observations of 24 FIR-bright ellipticals, as well as five other early-type galaxies, including one FIR-faint elliptical, IC 2006, are reported. The detected ellipticals are found to have typical molecular gas masses of about 10 to the 7th - 10 to the 8th solar masses, similar to their H I masses, and an approximately power-law distribution of M(H2)/L(B), extending to much lower values than for the spirals. The lenticular galaxies have CO properties intermediate between the elliptical and spiral systems. It is concluded that these ellipticals have global interstellar medium properties similar to those in late-type galaxies, but on a much smaller scale. A comparison of the properties of those ellipticals which have been detected in CO with the undetected galaxies indicates that the molecular gas may occur preferentially in the bluer, lower luminosity dwarf ellipticals, which have more than twice the detection rate of the brighter galaxies.
