Entocristid

A metastylid is present at the base of the metaconid, and an entocristid is in an intermediate position between the metastylid and the entoconulid.

C₁ with enlarged concave mesiolingual fossa, no lingual entocristid but a distinct vertical torus; long precristid; horizontally disposed lingual cingulum with no basal bulge of enamel or distobasal notch; small distal surface for C¹ occlusion.

At this state of wear, a small entocristid anterior to the entoconid is evident, and is apparently larger on m2.
