Diagnosis

Original diagnosis : Proximal limb short, stout, curved, faintly and sparsely pitted, and witli a row of distinct punctate markings where it borders the girdle, and a similar row parallel to it on the girdle itself, bearing on the ventral side the sail supported by thickened curved bars top and bottom, ¡and bordered with parallel peripheral thickened lines with two lateral flaps beneath ; proximal margin of girdle expanded into a wide high collar unmarked in its lower half, but with a reticulum of fine nerves on the upper half, open on the dorsal and ventral sides and supported by thick upright bars at the openings, one side decurrent in a large wide expansion, which meets the sail and forms in fact itself an upper sail with reticulate nervation  and a border like that of the lateral sail ; upper margin of girdle forming a long, narrow, tubular funnel expanding slightly above and toothed at the edge; distal limb suppressed, and represented only by a minute membrane at the base of this funnel
