Obs. Between Ph. Trumpo and the above species, the 

 Baron tinds no distinction. Between Ph. Catodon (Svinewal) 

 and Macrocephal us he considers any diflerence in teeth to be 

 the result of age. Ph. Macrocephalus of Gmelin, v/hich 

 forms the Sub-genus Phi/salus of Lacepede, rests only on a 

 bad figure of Anderson's, and is considered doubtful both 

 by the Baron and I\I. Desmarest.

 racle situated at the end or ?iear the end of the upper part of
