picture of a group of zoophytes, and a tall specimen 

 of K. falcata makes a prominent object in the centre 

 of the group.

" The fishermen have given them the name of Bottle 

 Brushes."— FlUs. 



This zoophyte has an erect, filiform, zigzag stem, 

 surmounted by a tuft of short branches arranged so as 

 to form whorls round the stem. (Four branches form a 

 whorl). As the stem grows the lower whorls decay 

 and fresh ones shoot out above, so as always to preserve 

 the "bottle-brush^^ appearance. The colour is dark 

 bom. The cells are alternate, closely pressed, and 

 arranged in two rows. They taper towards the orifice. 



Mr. Mcintosh (St. Andrew's Fauna) has found 

 specimens of the species with a short secondary 

 stem.

 and S.), Cellaria lonchitis {Lamh.), Nigellastrum arti- 

 culatum [Oken), Sertularia lichenastrum (Lamx., Berk., 

 Stew.), Biseriaria articulata (De B.).
