Lucernaria. 
Dunluce Castle, county Antrim, in great numbers ; July 1815,” Tem- 
pleton. Berwick Bay, rare. 
Our figures represent this beautiful animal in its natural size. The 
individuals from which they were drawn were of a clear pinkish red 
colour, but Montagu says that it is “ pellucid, green, brown, purple,

jection in the centre of the cupped expansion, exactly opposite the 
contracted base. 
In the specimens which furnished the vignette to this order (Fig. 
28,) there were nine glanduliferous tufts ; and Montagu’s figure re- 
presents a monstrosity with seven only, but as there is no appearance 
of marginal tubercles in it, the figure may belong to the following
