In 2001, Lenz and Kozłowska-Dawidziuk assigned the name Sagenograptus (species name S. arctos) to a late Wenlock retiolitid graptolite from Arctic Canada. We thank Rimma Sobolevskaya for subsequently informing us that the name Sagenograptus (species S. gagarini) had, already in 1962, been applied by Obut and Sobolevskaya to a Tremadoc dendroid graptolite from Taimyr. The generic name for the Arctic Wenlock retiolitid is here changed to Sagenograptoides.
