This Coralline differs very much from the fetacea, or 

 fmall briftle : it is three inches high, twice as big every- 

 way as the other ; and differs not only in being jointed, 

 but the denticles are half bell-fhaped, and much nearer 

 together ; befides, the ovaries are in clufters all along the 

 upper fide of the ftem, and when the young ones are 

 ready to come out, the tops of the ovaries are divided 

 like a coronet. This defcription is taken from a very 

 good fpecimen, preferved in fpirits, with its polypes and 

 ovaries perfectly diftinct.

Little Sea-brijlh Coralline. 

 ^his Coralline has a fingle 



pennated ftem ; the pinnse, or 

 fmall fide branches, are alter- 

 nate and a little bent : the 



ovariis oblongo-tubulatis denticles are but juft vifible ; 



axillaribus. they are on the upper fide of 



the little branches, and very 

 remote from each other : the 

 ovaries come out juft above the 

 infertionof the little branches, 

 and are of an oblong tubulous 

 fhape.

This little beautiful Coralline, which is about one inch 

 and an half high, is more frequently met with than the 

 former.
