is consequently more readily obtained with its living 

 inhabitants. 



Plumularia pennatula, A very elegant and delicate species, 

 sparingly found on this shore ; probably often overlooked 

 from its diminutive size. Fine specimens are found 

 growing on Cardium aculeatum. 



Plumularia myriophyllum (Pheasant's tail Coralline). This is 

 one of our most beautiful zoophytes when in perfection ; 

 the colour is nearly amber, with something of a metallic 

 lustre. It is not common, but we have repeatedly found 

 it at Southport. 



Plumularia frutescens (Shrubby Coralline). This species we 

 have several times picked up on the shore ; it has a 

 considerable resemblance to small specimens of Haledutn 

 halecinum, but is darker coloured ; the most distinguishing 

 character is its varnished appearance. It attains the 

 height of four inches, but with us seldom exceeds two or 

 three; grows on shells and stones, but is but seldom 

 found, except after severe storms or very heavy spring- 

 tides. 



Laomedia dichotoma (Sea-thread Coralline). Growing on 

 stems of fuci, sea-weeds, and on other zoophytes ; is of 

 very slender form, but extends a foot or more up the 

 stalks and over the shells on which it is located. Found 

 in large masses, along with its numerous congeners, after 

 strong winds or high tides. 



Laomedia geniculata (Knotted Sea-thread Coralline). Much 

 resembling the last species, but generally more upright 

 in growth. Found on the stems of fuci, and, under 

 similar circumstances, with the other species.
