P2 obliquely triangular, smaller and less trans- verse than P3. P34 similar but progressively larger, strongly transverse, with persistent median internal fossette, very large and prominent parastyle, and labial face of ectoloph posterior to the parastyle excavated, with basal cingulum. Postero-internal cingulum of P4 barely larger than antero-internal cingulum and not cuspidate or projecting to form a hypocone. Upper. Fig. 2. Adiantoides leali.
