118 PROCEEDIXOS OF THE ACADEMY OF [Jan., 



fragments, probably referable to the long-fingered crab, are in tbe 

 collection from Crosswicks, X. J. 



Still other fragments (PI. I, fig. 18) are strongly spinose. I 

 take that figured to be a portion of a hand from which the fixed 

 finger has been broken ofi' at the position marked f. The opposite 

 side bristles with three irregular rows of short spines, Avhile smaller 

 ones are scattered over the palm. The socket for the dactylo- 

 podite is very large. 



These fragments are so strongly marked and easily recognizable 

 specifically that I call the species Cancer (^f) whitfieldl ; the generic 

 reference being admittedly merely provisional and to call attention 

 to the necessity of examining further material; for it would be a 

 Cancer only in the Linurean limits of that genus. These fossils 

 are from Burlingtor county, N. J. The name is for Prof. R. P. 

 Whitfield, whose volumes upon the paleontology of New Jersey 

 have been of great use to workers in this field. 



There are also some densely granulose remains of portions of 

 limbs, possibly referable to Hoploparia or Adaeodes, in the collec- 

 tion of the Wagner Institute from Lenola, N. J. ; but they are too 

 imperfect to afford data of value at present.
