They are named after their locations, e . g . a paraconule is located between a paracone and a metacone, a hypoconulid is located between a hypoconid and an entoconid.
22.
There is a well-developed cingulid at the outer back margin ( distobuccally ), between the hypoconid ( one of the main cusps ) and the hypoconulid ( a smaller cuspule ).
23.
No other cusps are visible in the talonid, but the specimen is worn and poorly preserved; the posterolophid, a crest descending from the hypoconid, may end in a small hypoconulid.
24.
Like the upper teeth, they bear four cusps ( metaconid, protoconid, entoconid, and hypoconid ), four lophs ( metalophid, mesolophid, hypolophid, and posterolophid ) and three valleys.
25.
The main cusps, the buccal hypoconid and lingual entoconid, are opposite each other on the margins of the tooth ( the entoconid is further to the front in " Phenacopithecus " ).
26.
The smaller hypoconulid cusp is present towards the inner side of the tooth, and the hypoconid and hypoconulid are connected by a cutting edge which is suggestive of the presence of a metacone cusp on the upper molars.
27.
The protoconid, another cusp on the labial ( outer ) side, is connected at its back to a longitudinal crest, which in turn anchors the transverse mesolophid crest, and then joins the hypoconid labial cusp.
28.
In " Indraloris himalayensis " lower molars, there are four main cusps ( protoconid and metaconid in the trigonid, hypoconid and entoconid in the talonid ), which give the crown a rectangular aspect, although the labial cusps ( protoconid and hypoconid ) are placed somewhat anterior to their lingual counterparts.

Muirhead ( 1997 p . 372 ) describes " W . ridei " as having the following features that are unique : parametacrista on the first molar is straight, entoconid either missing of combined with the hypoconid in a more posterior position, the loss or reduction of styler crests, small metaconid, talonid basin reduced by the Ngamalacinus ", and that is the metaconid and protoconid are reduced.
