ORDER CRINOIDEA. MICROCRINUS CONOIDEUS. N. G. 



(Figs. 246 & 247.) 



Body conical ; sub-pentangular at base ; 

 areas five, oblique ; pores six or seven to 

 J^ ^p 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 247 shows the base with the intersecting bars and 

 triangular spaces between. 



I am unable to determine whether 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. 



Eocene of Craven county, and associated with Echinocya- 

 mus Parvus.

BRYOZOA. LUNULITES BENTICULATA. (FigS. 248 & 249.) 



" Conical ; cells inalternate, oblong externally, interior coni- 

 cal, nearly vertical to the two surfaces of the polypidom ; 



margin of the cell in its immature 

 state open and denticulated ; when 

 mature, covered ; mouth near the 

 distal extremity; semicircular when 

 imperfect, circular when perfect ; 

 gemmuliferous chamber at the dis- 

 tal end of the cell, opening round, 

 concave surface furrowed, irregular 



and minutely granulated." * Miocene, and common to most 

 of the beds upon the Neuse and Cape Fear.
