Body more or less cylindrical in expansion, with a distinct, flat, 

 muscular, basal disk. Tentacles round, simple, surrounding the buc- 

 cal disk in few or many cycles, sometimes obsolete. Walls perforate

This extensive family may be divided into several sub-families, 

 which are, however, not always well defined. 



1. Bunodinoe. Column bears tubercles or verruciform suckers, 

 which are imperforate, or rarely perforate, but do not emit acontia. 



2. Sagartinm. Column perforated with special pores, for the emis- 

 sion of acontia. Surface smooth, or with inconspicuous contractile 

 suckers. 



3. Phellince. Column elongated, covered to near the mai-gin with 

 a persistent epidermal layer or tunic. Lateral pores and acontia few, 

 or entirely wanting. 



4. Actinince. Column smooth, fleshy, destitute both of verruciij or 

 suckers and special pores. No acontia. Margin with or without col- 

 ored spherules. Includes ActinidcB and Anthead<B Gosse.
