I have fome elegant fpecimens from the Eaft Indies, 

 that approach very near to this kind, but they have no 

 radical tubes, and their fides bend inwards.

This elegant little Sea Matt I found growing on a red 

 pennated cartilagenous fucus, called Fucus Nereideus, 

 from the Mediterranean Sea. 



The cells when magnified appear furrounded by inarp 

 denticles, with a briftle fituated in the front of each cell, 

 bending inwards like a horn : the mouths of the cells in- 

 cline forward, and their whole femi-tranfparent fubftance 

 appears full of fmall points. I am indebted for this, 

 among many other rare fea productions, to my ingenious 

 and worthy friend Dr. John Fothergill, F. R. S.
