In shape they are mostly of some form referable to the cuneate form.
At the time of metamorphosis, young are dark brown with specks of black and with a dark, cuneate, leaflike middorsal mark.
Tail very short, rounded or cuneate, of fourteen or more feathers.
Divisions few, stalked, from cuneate to roundish-ovate, toothed or incised at the apex.
The lesion is one of the left occipital cortex in the cuneate lobe and the neighbourhood of the calcarine fissure.
Such a loss agrees with a lesion involving the upper part of the cuneate lobe above the calcarine fissure.
Valve linear, with cuneate ends; otherwise as in S. pinnata.
Valve rhombic-lanceolate, with cuneate ends and produced apices.
Valve symmetrical in zone and valve view along the sagittal line, but asymmetrical to the transverse axis, cuneate.
Valve clavate, with cuneate, acute apex; axial area distinct; central area unilateral with one stigma.
