Abstract: The shallow faint-end slope of the galaxy mass function is usually reproduced in Lambda cold dark matter (Lambda CDM) galaxy formation models by assuming that the fraction of baryons that turn into stars drops steeply with decreasing halo mass and essentially vanishes in haloes with maximum circular velocities Vmax <20-30 km s(-1). Dark-matter-dominated dwarfs should therefore have characteristic velocities of about that value, unless they are small enough to probe only the rising part of the halo circular velocity curve (i.e. half-mass radii, r(1/2)
