A) Complete polygastric stage; B) Eudoxid stage; C) Anterior nectophore

Description
Polygastric phase: Both nectophores characteristically opaque with white ridges. Anterior nectophore: Size: 3.9 mm in length; 2.5 mm in breadth; Somatocyst-1.75 mm; hydroecium-1.85 mm nectosac-1.6 mm in length. With 7 facets-dorsal and ventral facets pentagonal in shape; baso-lateral facets elongate and broad; apico-lateral facets rectangular in shape. The somatocyst has no apical projection. Somatocyst globular, without any other branches and with a short stalk, occurring anterior to nectosac and hydroecium. Hydroecium small, conical, with broad opening. Nectosac small, lying beside hydroecium with 4 simple radial canals; lateral canals not arched.
Posterior nectophore: Length-9.35 mm; breadth 6.75 mm. With 4 whitish ridges, dorsal ridge being absent. Ridges not prominent in well developed nectophores, and therefore, smooth and barrel-like in shape. Ostial teeth not pronounced, but keel-like in appearance. Ostial end twisted, displacing right lateral ridge and left ventral tooth. Ventral ridges forming hydroecial wings not fused, two flaps from these wings over lap, firmly held in place. Nectosac with simple radial canals.

Eudoxid phase: Referred to as "Sphenoides" from a prior name of Huxley, 1859.

Bract: Upto 9 mm long, with 7 facets. Ridges milky-white. Four apical facets meet at tip, two elongated sloping baso-lateral facets, and a dorsal facet. Baso-sagittal ridge long. Phyllocyst with only 2 branches-thick, oval shaped anterior, and thin, thread-like posterior branches.

Gonophore: Upto 6.8 mm length and 3.67 mm in breadth, with 4 milky-white ridges, ending in 4 conspicuous teeth at base.
