74 GLAUCUS; OE, 



sters' horns, and wliat not, are zoophytes of different 

 kinds. Here is Sertiilaria argentea (true squirrel's 

 tail), here, S. filicula, as delicate as tangled threads 

 of glass. Here, abietina; here, rosacea. The lob- 

 ster's horns are antennaria antennina; and mingled 

 with them are PlumulariiB, always to be distin- 

 guished from Sertulariae by polypes growing on 

 one side of the branch, and not on both. Here is 

 falcata, with its roots twisted round a sea-weed. 

 Here is cristata, on the same weed ; and here is 

 a piece of the beautiful myriophyllum, which has 

 been battered in its long journey out of the deep 

 water about the ore rock. Tor all these you must 

 consult Johnston's Zoophytes, and for a dozen 

 smaller species, which you would probably find 

 tangled among them, or parasitic on the sea-weed. 

 Here are Flustroe, or sea-mats. This, which smells 

 very like verbena, is Flustra coriacea (PL I. Fig. 2). 

 That scurf on the frond of oar weed is F. lineata 

 (PL I Fig. 1). The glass beUs twined about this 

 Sertularia are Campanularia syringa (PL I. Fig. 9) ; 

 and here is a tiny plant of Cellularia ciUata (PL I.
