REMARKS

Both specimens figured, the holotype and paratype are fragmented and poorly preserved and badly imaged, so that it is difficult to see what is being figured, however the description indicates an inner spicule it is possible this taxon is an entactinarian. A trilobite genus described by Maksimova (1978) bears the same name.
