Paraperrinites
[Tumanskaia, 1949, p.57: Conch discoidal, with thin, convex venter.  Umbilicus not large.  Sculpture expressed by thin radial growth lines or by nodules.  Lobe line consists of a ventral and five lateral lobes on the outer side and of one lobe on the
umbilical wall. Both halves of the ventral lobe and each lateral lobe with a large prong at the base.  On the sides are some
prongs of simple shape.  Some species show doubling of some prongs at their tips.

Representatives of the genus Paraperrinites are distinguished from the genus Abichia and from its subgenus Properrinites
Elias by a more complicated lobe line:  Paraperrinites has two to three prongs on each half of the ventral lobe and both
Abichia and Properrinites may have none to one prong on the lobes of the outer side; they posess one to two prongs on
lobes of the inner side.  All lateral lobes have the same shape in Paraperrinites, the fourth and fifth lobes of Abichia and
Properrinites strongly differ from the rest (most are only two-pronged).  Paraperrinites differs from Perrinites
by its less complicated lobe line, lesser number of lobes, which are subdivided to a lower degree; Perrinites has not merely
(simple or subdivided) prongs on top of both halves of ventral lobe and on first lateral lobe: whole rami, carrying from 3 to 6
lobes, are present.]

Metaperrinites:
[Leonova, 1989, p..129:] Conch subdiscocone or pachycone, involute.  Umbilicus tight.  Lamellae thin, straight on lateral
sides and form a wide, low sinus on venter.  Ventral lobe with moderately wide, serrated prongs.  Lateral lobes commonly wedge-shaped, serrated, in the upper lobe part sometimes secondarily serrated.  Third lateral lobe wide, almost divided into two individual lobes, the inner one (fourth) smaller and thinner than the outer one (third).  The dividing saddle is lower than other saddles.  Fifth lobe (originally umbilical) not large, umbilical lobes small.  Dorsal lobe wide,trifid.  Inner lateral lobes weakly subdivided, the third is wide and bifid.
