The detection of CO(2 - 1) emission from five positions within the blue elliptical galaxy NGC 3928 (Mrk 190) is reported. The spectra indicate discrete components with a velocity gradient of about 190 km/s over a projected distance of about 2 kpc and a total CO luminosity of 800,000 Jy km/s sq Mpc. The CO emission implies a mass of roughly 5.1 x 10 to the 8th masses of H2. Compared to a H I mass of 2.8 x 10 to the 7th solar masses, the mass ratio of H2/H1 is at least 18 in the inner region of the galaxy, a situation similar to what is seen in the inner regions of spiral galaxies. 17 refs.
