volume of the Philofophical Tranfacftions, accom¬ 
panied by fome farther obfervations by Mr. John 
Hunter. From the figure there given, and which 
we have here copied, as an illuftration of this par¬ 
ticular, it appears that the animal fhould be con- 
fidered as a fpecies of Terebella, which, when it 
has formed itfelf a hole in the madrepore, continues 
to refide there, and may be fuppofed to protrude 
itfelf occalionally from its cell in queft of prey. 
Fig. i. The animal taken out of its cell. 
Fig. 2. A piece of the madrepore, with the cell 
in which the terebella relides.
