Arkell, et al. 1957, in Part L of the original treatise lists instead: Hungarites, Noetlingites, Longobardites, Neodalmanites, Groenlandites, Perrinoceras, Arctohungarites, Dalmanites, and Prohungarites. Only two have remained, Hungarites and Perrinoceras. Longobardites has been removed as type genus for the Longobarditidae, along with Arctohungarites, Groenlandites, and Noetlingites.
