(?) Culicocrinus spinosus new species 
Plate II, figs. 4, 4a-c 
This name is given to a solitary specimen from Tennessee, with much 
doubt as to its generic affinities, but chiefly on account of the five large spinifer- 
ous interlocking orals, which differ from those of the typical species in having 
the posterior plate flanked on the outer side by anal structures and smaller 
lateral plates, but nevertheless present considerable similarity in proportion 
and general arrangement. The primibrachs are also less deeply incorporated 
in the cup.
