Hatchericeras lakefieldense Woods, 1962, is difficult to interpret. It looks like a representative of Hatchericeras, but seems more evolute, with a wider umbilicus than the type species, H. patagonense, when adult. Occurrence Barremian, Hatchericeras patagonense Zone of the Austral Basin, Argen- tina, and Makatini Formation, Barremian I, Locality 170, Mlambongwenya Spruit, Zululand.
