#3859, single zooid, about 3mm in length, possibly immature; yellow in life, color faded in formalin.

Muscles cover about half the body on the left, most of the body wall on the right. Longitudinal vessels mostly complete, a few are incomplete. Agrees morphologically in every aspect with the detailed description and figures in Kott (1985). No gonads.
