LKW is very narrow, <5% of MAW and with a distinct groove between the lateral keel and case proper. This groove is not present in any other ENP skate egg case. Lateral keels extend onto horns and are also present on inner horns. Anterior apron border of egg case broad and concave, anterior horns more robust than posteriors at base, becoming flattened and threadlike at tips. Posterior apron is nearly straight, broad, and transverse, about

Attachment fibers present, originating on lateral keel near the junction of exterior base of posterior horns and case. Egg cases removed from a single specimen was a light golden brown in color.

To the best of our knowledge this is the first confirmed record and description of the egg case of this species.
