This zoophyte is generally three or four inches high, 

 though Mr. Hyndman has dredged it on our west of Scot- 

 land coast six, and in one instance, ten-and-a-half inches in 

 height. It is a remarkably handsome zoophyte, of a palish 

 horn-colour, clean and clear ; the pinnrc, which are subalter- 

 nate, branching out like polypody, whence its English name. 

 The cells are in rows on each side of the pinna3. The vesi- 

 cles are generally on the upper side of the pinnae, though 

 occasionally on the under. I have some finely branched 

 specimens of it from Mr. Tudor at Bootle.
