Veficulated Corallines. 5* 



regular Branches, that have the Appearance of the Fir-tree, 

 or, as feme think, of the Fern ; the Branches of this extend- 

 ing themfelves in the fame Diredion with the Leaves of that 

 Plant. 



The Denticles are placed alternately, and have narrow 

 Mouths or Openings. On feveral Parts of this Coralline we 

 may obferve oval-fliap'd Veficles, or little Bladders, which 

 are inferted in the Stem, and have a Communication with 

 the internal Part, by a fmall Opening at the Bottom of each. 

 Their Necks are narrow near the Top, like a Pitcher ; and, 

 in fome Specimens colleded in the Month of Aprils we have 

 obferved the Remains of Animals like Polypes, fixed by the 

 Tail to the Infide of the Neck of thcfe Velicles, as in Plate 

 L Fig. B. where the dead Polype may be feen hanging out 

 of the Veficle. Many Specimens of this Species are found of 

 a reddifli Colour ; tho' almofl all the Corallines are of a 

 fading yellow or brown Colour. We often find fome of this 

 Species full of white fpiral Shells, hke a minute Cornu Am- 

 monis \ and others over-run with a fmall bell-fhap'd Coralline, 

 which will be defcribed hereafter.
