notes and nothing corresponding to them can be seen npon the speci- 

 men. Whether they be mere color spots, disk pores, or tubercles, is 

 uncertain. When fully expanded the column showed longitudinal 

 lines. 



According to Mr. Bradley's notes it is a hardy species, feeds well, 

 and bears rough handling.

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 

 or imperforate. Ambulacral appendages on the sides of the body 

 various. 



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

 which are, however, not always well defined. 



1. Bunodinm. Column bears tubercles or verruciform suckers, 

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



2. Sagartiiue. 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 margin mth 

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

 or entirely wanting. 



4. Actinime. Column smooth, fleshy, destitute both of verruca? or 

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

 ored spherules. Includes Actmidce and Antheadce Gosse.
