Holotype . UT90142 (internal mould of cranidium). Paratype material. UT90113 (librigena), UT90144 (librigena), UT90155 (librigena), UT90094a,b (pygidium), UT90115 (pygidium), UT90121 (pygidium). Locality. Ray’s Hill, St. Mary’s, Tasmania. Emended diagnosis. Species of Doublatia with a median preoccipital lobe and parabolic-shaped cephalon. Pygidium with eight axial rings and seven pleural ribs. Remarks. Doublatia pyriforme differs from the type species in that it has an obvious preoccipital median lobe, and a parabolic-shaped cephalon. Doublatia pyriforme also has a triangular L1, whereas the L 1 in D. inflata is much more rounded.
