The first record of O. erythrogrammon from Isipingo was found in a crevice at the highwater mark. The specimen has a mucilaginous cap covering the posterior end of the trunk. The anatomy shows that the intestinal siphon terminates posteriorly at the opening of the rectal diverticulum into the rectum. There is a pair of anal vesicles beset with numerous stalked ciliated funnels. Replacement setae are found associated with each of the two functional setae. Each nephridium is provided with a single outgrowth which divides into two coiled appendages. There are 12 muscle bundles of limited extent.
