(Figs. 246 & 217.) 



Body conical ; sub-pentangular at base ; 



FIG. 246. FIG. 247. areas five, oblique ; pores six or seven to 



^^ ^^ each, alternating and arranged in rows, 



separated by a ridge ; apical pores five, 



base wide ; beneath concave; concavity intersected by five 



bars, which descend and meet in the center ; spaces between. 



triangular, terminating above in the apical pores. 



Figure 24:7 shows the base with the intersecting bars and 

 triangular spaces between. 



I am unable to determine w r hether the head is supported on 

 afoot-stalk; the joints of a crinoid, however, are. numerous 

 in the marl in which this curious species is found.

&quot; Conical ; cells inalternate, oblong externally, interior coni

margin of the cell in its immature 

 state open and denticulated ; when 

 mature, covered ; mouth near the

 imperfect, circular when perfect ; 

 gemmuliferous chamber at the dis

 concave surface furrowed, irregular 



and minutely granulated.&quot; * Miocene, and common to most 

 of the beds upon the JSTeuse and Cape Fear.
