of theancients, and it is alfo highly probable that the 
fmall frefh- water animals called Hydre or Polypes 
in modern natural hiftory, are confiderably allied in 
general habit to the Sepiz, and their arms or ten- 
tacula when microfcopically examined, feem befet 
* with numerous verrucze which probably act in the 
fame manner as the acetabula or fuckers on thofe of 
the Sepiz. It may alfo be obferved that the Loligo, 
inftead of the friable calcarious bone with which the 
common or officinal Cuttle-Fifh is furnifhed, has 
on the contrary a long, lance-fhaped, tranfparent 
cartilage in place of the bone; and this cartilage 
has fometimes been defcribed and figured as a fpecies 
of pennatula, under which name it may be found in 
the third volume of Seba’s Thefaurus, p. 40. pl. 16. 
and even in fome of the earlier editions of the Syf- 
tema Nature of Linnzus it was erroneoufly placed 
under that genus.
