amazing lultre, that marks the path of the animal 
wherever it directs its courfe, and which in the minds 
of the timid and fu perditions, creates images of danger 
of the mod tremenduous kind. 
Linnaus enumerates nine different fpecies, one only of

quarter of the globe. They are all characleril'ed by a 
long projection from the forepart of the head, of a light 
and empty fubllance. The antennte are feated below

is largeft, and of a globular form ; the roftrum is bended
