Capsule:
 Relatively delicate texture, smooth surface.
 Widest across its ‘waist’.
 Very similar to Spotted Ray, but generally larger.
Capsule Size:
 Approximately 70-90mm long x 45-60mm wide excluding horns (when soaked).
Horns (when present):
 Top pair of horns approximately as long as capsule.
 Tips (if present) tend to curl in towards one another.
 Bottom pair of horns curl laterally, giving a ‘bobsleigh’ impression.
Tips of horns (if present) are thin and curly.
Lateral keels:
 No keels present.
Fields:
 Very shallow fields present between both pairs of horns, although these may not be present due to having been worn off.
Characteristic features:
 Very similar to the Spotted Ray eggcase, the only major difference being that Undulate Ray eggcases are generally much larger (possibly up to twice as large).
