10 CEPHALOPODA. LOLIGINID&. 
Inhabits the European seas, very often occurs on our own 
coasts, and is sometimes gregarious. The eggs resemble a 
bunch of grapes. 
This animal was well known to Aristotle, Athenzeus, Oppian, 
and other of the ancient naturalists. Aristotle did not over- 
look the cartilage at the base of the feet, which, he observes, 
is placed between the eyes, containing a little brain. The same 
author likens the supplementary arms to proboscides. He was 
well acquainted too with their eggs, which he has accurately 
described, and has detailed the amours of the Sepze; but I do 
not give the least credit to what he has said on this latter subject. 
The black liquor was likewise known to the ancients, who 
sometimes used it as ink, naming it Atramentum, believing 
that it was used by the animal to cloud the water when it was 
followed by its enemies.
