fessor K. Forbes; Sana Island, off Kintyre, Mr. Hyndman ; 
Liverpool, Mr. H. Johnson; Whiteburn, Miss Dale; Scar- 
borough, Mr. Bean; Bootle Bay, Mr. Tudor; Cornwall ; 
Devon; Norfolk, Mr. Peach. 
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 pinne, which are subalter- 
nate, branching out like polypody, whence its English name. 
The cells are in rows on each side of the pinne. The vesi- 
cles are generally on the upper side of the pinne, though 
occasionally on the under. I have some finely branched 
specimens of it from Mr. Tudor at Bootle. 
Genus VIII. ANTENNULARIA, Lobster’s Horn 
Coralline, Lamarck. 
Gen. Char. Polypidom plant-like, horny, simple or branched 
irregularly, the shoots fistular-jointed, clothed with hairlike verti- 
cillate branchlets; cells small, sessile, campanulate, unilateral ; 
vesicles scattered, unilateral. Name from the feeler of an insect. 
Polypes hydraform.—Johnston.
