Shimer and Shrock, 1944, Index Fossils,p. 595, pl. 248, fig. 7.Hyatt is perhaps the latest author to discuss this species extensively,but, as is his habit, he describes specimens in minute detail hut nowhereactually defines the species. From his discussion it may be inferred thathe had in mind ammonites that displayed no umbilical shoulder, hadsmooth flanks and compressed shells, and had a suture with abont fivebilobed saddles, the remaining seven or eight being entire.Range in New Jersey-TINTON: Tinton Falls, Beers Hill cut, near Freehold.Range outside New Jersey-Maryland, Mississippi.Type.-Location unknown, presumably lost.
