The specimens assigned to Mesodema venulosa and Redlichia idonea by Whitehouse are reillustrated and reanalysed. Mesodema is considered a synonym of Redlichia (Redlichia), while Redlichia idonea is not considered synonymous with R. forresti. Redlichia idonea is a very large trilobite, probably attaining a maximum length of 20 cm, while the single cranidium of R. venulosa is about half that of a large R. idonea. Redlichia venulosa is easily distinguished from R. idonea by its much wider cranidium and narrower glabella.
