"The European Eocene primate genus Protoadapis, as generally conceived of, is long-lived and highly speciose, but nonetheless homogeneous. Reappraisal of the material involved shows, however, that among the 10 species allocated by Gingerich (1977) to Protoadapis and its closest relatives Cercamonius and Pronycticebus, three separate groups are discernible, together with three individual species that are clearly misattributed. Within the genus Protoadapis we recognize for the moment two species, P. curvicuspidens and P. recticuspidens, both originally described (as species of Plesiadapis) by Lemoine in 1878. These two differ somewhat in trigonid morphology, but both are quite distinct from all other material subsequently referred to Protoadapis. As thus constituted, Protoadapis may be most closely comparable to Agerinia. A second genus, by priority Pronycticebus, is represented by material formerly allocated to 'Protoadapis' (or Europolemur) klatti, as well as by Pronycticebus gaudryi and by a new species we describe here. Pronycticebus may possibly bear affinities with certain Pelycodus. The third major morph in the assemblage is comprised of specimens allocated to 'Protoadapis' angustidens (now filholi), 'Protoadapis' (or Cercamonius) brachyrhynchus, and possibly 'Protoadapis' weigelti; the earliest available name for the single species represented by this material is Cercamonius brachyrhynchus, and its affinities lie with the larger species of Notharctus. The species 'Protoadapis' ulmensis, based on isolated teeth, appears to be related to Adapis, the genus in which it was originally described, and the affinities of the two species 'Protoadopis' russelli and 'P.' louisi are unclear"--P. [1].
