Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L.I. Price 1937 | Skull slender and acuminate. Snout rather sharp. Eyes large, centrally located. Parietals deeply emarginated along occipital crest. Vestigial otic notch with reduced supra-temporal and parietal above and squamosal below. The supra-temporal does not appear to touch the postorbital. Occipital plate slanting gently backward from crest. Pineal foramen quite small and quite close to occipital crest, resembling closely the more specialized pelycosaurian condition. |
