M - The anterocone is always bifid. The labial epiphysis is present in 85% and always long. Both the lingual and labial anterolophs are long, and generally reach the margin of the frontal cones. From both anterocone s an anterolophule starts, of which the labial one is sometimes not connected to the appendix of the paracone. In these cases, between the anterior cones, no island develops. The mesoloph is always long. On the strong cingula the mesostyle and entostyle is frequent in the form of small cusps. In most cases the connection of the metacone and hypocone is closed. In a few cases, however, the crest leads toward the cone only from the root of the mesoloph.

. An oval-shaped island is enclosed between the two anterior cones. The mesolophid is always long, reaching the margin of the tooth. Both lateral cingula are well developed at the sinus. There is an island-forming tendency also between the two posterior cones, and these are present at different evolutionary stages. The metacone can be joined to the hypocone system in three ways: from closing cingulum (27%), from the hypolophulid (13%) and from both sides (46%). There are cases (10%) that these ridges are joined only on the margin of the metacone, but do not pass its peak.
