GASTROPODAwith moderately impressed sutures, marked by narrow, rounded, verticalnodes which extend from suture to suture, from 16 to 20 being presenton each volution ; upon the outer volution the vertical nodes extendonly about one-third of the length of the volution below the suture, andat their base, towards the aperture, a revolving angle is gradually developedwhich continues into the spinelike lateral extension of tlieaperture."Ren1arks.-"Some impressions of the exterior of the shell show, inaddition to the characters enumerated above, that the outer volution isnearly smooth for a distance below the revolving angular ridge, andthen below this smooth area it is marked by rather fine revolving costae ;the entire snrfaee of the shell is marked by very fine revolving striae."(Weller)\\Teller's description was based on a very complete specimen, whercasthat of Whitfield's type was very imperfect.Range in New Jersey-AlERCHANTVILLE : 10Range oz~tsido Kew Jersey-Delaware.Type.-New Jersey: ANSP 1504i.Anchum abntpta Conrail 1860Plate 52, Figure 3A.nekura abrupta Conrad, 1860, Jour. ilcad.

If this specimen were complete it would have an additional heightat the apex of about 20 mm., and an anterior beak about 30 mm. inNEW JERSEY GEOLOGICAL SURVEY
