Fifth Order. — Les Heteropodes. 
Body free, elongated, swimming horizontally ; head distinct ; two eyes ; the arms 
not in the form of a crown on the summit of the head ; no foot beneath the belly 
or under the throat for the purpose of crawling ; one or more fins, not disposed 
in pairs, or any regular oi'der of distribution. These animals, though allied to 
the C^phalopodes, may be considered as the first vestiges of a series of marine 
animals, intermediate between them and the fishes, they probably are very nume- 
rous and much diversified, but have at present escaped observation, or their exami- 
nation has been neglected.
