Type species: Propinacoceras beyrichi Gemmellaro, 1887, SD Diener, 1921, p.12.

[Miller & Furnish, 1940, p.41: In all known species of the genus the conch is thinly discoidal, being flattened laterally and ventrally. The umbilicus is very small. The conch is expanded orad fairly rapidly: The living chamber is at least half a volution in length. The growth lines are slightly sinuous, and each forms a large ventral salient and on either side of it a broad shallow rounded sinus, a similar low broad lateral salient, and a rounded sinus which extends  to the umbilicus. The ventral side of the conch bears two rows of large low rounded nodes. During early adolescence the ventral zone of the conch is non-nodose, but as maturity is approached rounded nodes are gradually developed and become elongate transversely so that at full maturity they are in reality short ribs. Each suture fo the genotype forms a narrow ventral lobe, a broad first lateral saddle in the top of which are two small lobes, a moderately small first lateral lobe, a large second lateral lobe, and several auxiliary lobes and saddles. Except on the umbilical portions of the conch all the lobes are bifid. In most congeneric forms the first lateral saddle is more strongly divided and  there is therefore more like that of Artinska].
