" This curious coralline appears through the microscope 

 to be of the most singular structure of any yet described. 

 It consists of sundry branches, and every branch is com- 

 posed of many stout, united, small tubes, which at certain 

 equal distances send off small capillary screw-like stalks, 

 each of which supports a cup of a bell-shaped figure, curi- 

 ously indented round the brim. These are placed in such 

 a manner as to correspond exactly in point of situation with 

 the others, and to give the whole very much the appearance 

 of the plant called horse-tail, or Eqnisetuvi; the capillary 

 stalks and their cups being all disposed in whorls or like 

 branches for candles." {Ellis.) The pedicles are ringed at 

 top and bottom. The vesicles which arise from the stem 

 are smooth and short-stalked. The first specimens we liad 

 of this were from Mr. Tudor, Bootle.
