The following fourteen new genera are proposed ; Microsphaeridiorhynchus, with type species Rhynchonella (?) litchfieldensis Schuchert, C, 1903, from the Upper Silurian (and possibly the Lower Devonian); Oligoptycherhynchus, with type species Terebratula hexatoma Schnur, J., 1851, from the Middle Siegenian to Eifelian; Ypsilorhynchus and Solidipontirostrum from the Upper Eifelian and the Lower Givetian, with type species, respectively, Leiorhynchus manetoe Mclaren, D. J., 1962 and Terebratula pugnoides Schnur, J., 1851; Stenoglossariorhynchus, with type species Leiorhynchus awokanak Mclaren, D. J., 1962, from the upper part of the Lower Givetian and the Middle Givetian; Platyglossariorhynchus, with type species Pugnax proteus Torley, K., 1934, from the Middle and Upper Givetian; Platyterorhynchus, with type species Leiorhynchus russelli Mclaren, D. J., 1962, from the Upper Givetian and the Lower Frasnian; Phlogoiderhynchus, with type species Uncinulus arefactus Veevers, J. J., 1959, from the Lower Frasnian (an Upper Givetian age cannot be dismissed); Paurogastroderhynchus, Leptocaryorhynchus and Planovatirostrum from the Upper Famennian (the second one may perhaps also be found in the Lower Famennian, the third one in the Middle Famennian), with type species, respectively, Camarotoechia (?) nalivkini Abramian, M.S., 1957, « Camarotoechia » jamensis Brice, D., 1967, Liorhynchus planoovalis Nalivkin, D . V., 1937; Centrorhynchus, with type species Camarotoechia baitalensis Reed, F.R.C., 1922, from the Famennian (the lowest and uppermost beds excluded); Macropotamorhynchus, with type species Camarotoechia mitcheldeanensis Vaughan, A., 1905, from the Lower Toumaisian, and Corrugatimediorostrum, with type species Terebratula Rocky'Montana Marcou, J., 1858, from the Middle Pennsylvanian
