GASTROPODA 65Turbinella intermedia Weller 1907Plate 58, Figures 10, 11Turbinella intermedia Weller, 1907, p. 767, pl. 90, figs. 18-22.Description.-"Internal casts short fusiform to subglobular inform with about three volutions, the dimensions of two nearly completeexamples being: height, 18 mm. and 13 mm. ; greatest diameter, 17 mm.and 11.8 mm. Apical angle about 75", the spire about one-third thetotal height of the shell, the volutions increasing somewhat rapidly insize, subangular on the periphery and marked by rather strong verticalnodes, which become obsolete before reaching the suture above, and alsoa short distance below the periphery, about 12 nodes occurring uponthe outer volution; the last volution rather rapidly contracting belowand produced into a short anterior beak; columellar cavity of moderatewidth, bearing the impressions of three rather faint revolving folds."(Weller)Remarks.-"Only the internal casts of this species have been ohserved.These resemble similar casts of T. alabamensis, but they are alwaysshorter, with the volutions less regularly rounded over t.he pcriphery,and they do not attain so large a size. They differ from the castsof 7'. pnrva in being somewhat larger, in having a more elevaterl spireand in the more nearly vertical position of the nodes. The species is, infact, somewhat intermediate in its characters between T. a'nbamensisand T. parva, and has been obscrved only from the Mercha~ltville claymarl,xrhile these other two species are both Navesink species."Range in Xew Jersey-&~ERCIIANTVITJLE : 15, 16Type.-Lenola, NJSM 7769.Turbinella alabamensis (Gabh) 1860Plate 56, Figure 5 ; Plate 59, Figure 1Cancellaria Alabameasis, Gabb, 1860, Jour. had. h'at.
