CRETACEOUS FOSSILSSubgenus Palaenstac~ts Bell, 1850Enoploclytia IPalaeastacus) sp.Plate 80, Figures 3-5Descriptiou-Dactylus straight, ovate-triangular in section, graduallytapering distally. Teeth circular in section, about equal in sizeand spacing, more than their diameter apart. The distance betweenthe proximal (1st) tooth and the proximal end of the finger about equalto the spaee between the first and third tooth. Integument thick, studdedwith widely separated papillae and tubercles, the laster numerouson the upper surface of the dactylus where at least three arc on the midline.The posterior tubercle of this row of three forms an eqnilateraltriangle with a transverse row of two tubercles behind it. Articularnodes stout, conical, widely fiaired at the bases and placed slightly belowthe upper margin of the finger.The tip of this unique finger is lacking and most of the low subconicalto dome-shaped tubercles are broken. The occludenl surface haca median row of six teeth plus a tubercle which is situated to one sideof the midline between the third and fourth tooth. The lateral surfacesof the finger are flattish.Measurement of figured specimen : length 55.7, height Behind proximaltooth 15.2, thickness behind proximal tooth 13.O mm.Remarks.-This is the second giant Enoplocl7~tia that has beenfound in the Americas, the first being E. (P.) zudkeri (JQ~itfield, 1880.p. 37, pl. 16, figs. 1 a-c; pl. 17, fig. 1 a; Upper Albian; Texas), a specieswith a strongly curved and tapered dactylus. The straight dactylaraxis and coarse surface tnberculation of our species agree with the descriptionof E. (P.) image1 M'Coy (1849, p. 332 ; Senonian ; England) ;however, the dactylar teeth of M'Coy's species-which has never heenfigured-are said to be less than their diameter apart.Distributio?t.-Delaware: Merchantville formation: Spoil banknorth of Chesapeake and Delaware Canal about one-quarter mile eastof Summit Bridge, Delaware.Figured specimen.-WFIS No. 17079.Enoploclytia suhgen. et sp. indet.Plate 8P, Figure 6A rectangular fragment 1neas.1ring 30 x 40 mm., from the spoil banknear Summit Bridge, Delaware, represents the co?lrirx lateral surfaceof a large palm. Spinous tubercles ornament the surface and the positionof the carpopropodal articulation is marked by a broad, deepgroove. In the same block of clay close to the palm there is an imperfectmold of a large tubular finger. (ANSP 19734).NEW JERSEY GEOLOGICAL SURVEY
