Orthoceras cretaceptum pl.87 fig 2a Calucera Cerrucena type. pl 87-2a traces of transverse surface striae pl 86-1d, small form Partially same species as pl 87-2a > Mordilopsis fata. pl.35 fig 6 top, is cleaned up and looks like 6a, stronger curves around suture like Cylcerma, and permanent at break. Cyclomema percarinatum is more distinctly pyramidal. =type. Murchisoni? tellicincta = more rapid spire than Rogers Group. >Mordilopsis fata in the looks like >Graini form but has suture more radial, Cannularia 4th form, x 2 faces, type Zygophora recurvistris = our type but varrion Orthoceras aeguale. >Rhytistnyja 1130-1 mm. from as Mordilopsis mordeliana? >Patrzyga Cyclophora, Camarella Zygophora Murchisona tellicincta of Rogers Group type but larger apical angle. Cannularia granulata, Orthoceras contracta A + Wh. Artinista contracta Hall. pl.82 fig 8 top Cinchmatis. Ref these 86 shows strong sharp winding Cymatinita lyre, way up to break. These sharp wrinkles of 8a are nearly obsolete, or at least are very weak. Nearest to C. contracta of which except in size, unless it is a true Orthoceras, would it resembles mine in form.
