A well-developed, purely ectodermal spur grasps round the margin of the exumbrella; the ocellus is placed immediately below the spur. In contradistinction to Sarsia tubulosa, the radial canal issues from the adaxial side of the bulb, close to the sulnimbrella, and the endoderm of the bull:) is not vaulting into the umbrella, neither behind nor in front of the radial canal (comp. Sarsia tubu- losa). The shape and the inner structure of the bulb may be seen in the figures. Colour.
