The Denticles are placed alternately, and have narrow 
Mouths or Openings. On feveral Parts of this Coralline we 
may obferve, oval-fhap’d Velicles, or little Bladders, which 
are inferted in the Stem, and have a Communication with 
the internal Part, by a {mall Opening at the Bottom of each. 
Their Necks are narrow near the Top, like a Pitcher ; and, ~ 
in fome Specimens colleéted in the Month of 4pri/, we have 
obferved the Remains of Animals like Polypes, fixed by the _ 
Tail to the Infide of the Neck of thefe Veficles, as in Plate 
I. Fig. B. where the dead Polype may be feen hanging out 
of the Veficle. Many Specimens of this Species are found of 
‘a reddifh Colour; tho’ almoft all the Corallines are of a 
fading yellow or brown Colour. We often find fome of this 
Species full of white fpiral Shells, like a minute Cornu Am- 
monis; and others over-run with a {mall bell-fhap’d Coralline, _ 
which will be defcribed hereafter:
