134 CRETACEOUS FOSSIliShowever, that the name is to be kept nearer home. The species is apparentlyassociated with dela.warenuis and the assignment to a differentgenus seems unexpected. The writer has arbitrarily followed Collignon.Range in New Jersey-RIERCHAXTVILLE : Burlington County.Range outsidc New Jorsey-Crosswicks (Merchantville and Woodbury) : Chesapeake andDelaware Canal.Typo.-ANSPDelaware.19492. Locality: Chesapeake and Delaware Canal,Submorionicerar sp.Whitfield (1892, p1.42, fig. 9 ; p1.43, figs. 1-2) figures as Ammonitesdelawarensis Norton a specimen 185 mm. in diameter, with maximu~nheight of whorl of 90 mm. and width of 60 mm. A little more than onewhorl is preserved and all of the early stages are missing. Only theumbilical and ventrolateral nodes are displayed, and the ribs are veryweak. The keel is visible but sub~lned. Collignon (1948, fasc. 14, p. 30)refers this specimen to Snbmortonicoras, and conceivably it could be alarge stage of S. vanztxemi, but as the authentic specimens of vam~cxenaiavailable are all small, it is not possible to assign it with assurance.Whitfield (1892, p. 252) refers to the specimen as "a large cast sentme, as one of the type specimens, from the Acad. Nat. Scicnees, Philadelphia,"and undcr the heading "Formation and locality" he says,"The type specimens are all from Delamare."
