. Genera now in the Flickiinae:
:'' Flickia'' Pervenquiere, 1907 - Shell smooth, moderately evolute, rather compressed, venter narrowly arched, suture smooth, undulatory. U Alb -L Cenom. N Afr, Madag, Texas. :'' Ficheuria'' Pervenquiere, 1907 - Shell very involute, globular, umbilical shoulder tending to be angular. Suture similar to that of Flickia. U Alb. -L Cenom. of North Africa. :'' Adkinsia'' Boes, 1928 - Shell rather more involute and inflated than ''Flickia'' but less than ''Ficheuria''; first lateral lobe narrower than on either. L Cenom, Texas. Genera placed in the Salaziceratinae:
:'' Salaziceras'' Breistroffer, 1936 - Described as small, moderately involute, inflated, with more or less straight, course, rounded ribs that arise from prominent umbilical bullae and sutures with simplified saddles. More closely resembles other Lyelliceratid genera except for the suture. U Albian, France. :'' Neosynoceras'' Breistroffer, 1947 - A dwarf, involute, globular form with sharp umbilical, ventrolateral, and siphonal (mid ventral) tubercles. L Cenomanian.
