This information is based upon various sources, but no personal knowledge. I am indebted to the late Alan Horowitz for his compilation, and to Dr. J. Pachut. I have reassigned many species of Semieschara to Onychocella without any critical review. Many of the species of d'Orbigny need further revision. As stated by Taylor et al (2018), many of the fossil species lack distinguishing features, and belong in the "stem-group" onychocellids.
I would be grateful for corrections to, or critical reviews of this information. This is not a 'final' version (an impossible ideal), but a working document.
