Column irregularly distensible, not mucous, somewhat versa- 

 tile, but generally forming a tall, erect, thick pillar, the summit 

 expanding ; the margin tentaculate ; the surface longitudinally 

 fluted (as if composed of a multitude of slender vertical cylinders 

 placed in contact side by side), each cylinder studded with a 

 single vertical row of minute warts. No suckers or loopholes. 

 Substance pulpy, membranous. 



Disk expanded, membranous, concave, revolute. 



Tentacles numerous, in several rows, long, lax, irregularly 

 flexuous, scarcely retractile. 



Mouth not ordinarily set on a cone, but pouted after the re- 

 ception of food ; lip thin. Gonidial tubercles prominent. 



Acontia wanting (?).
