The Narwhal, perhaps the strangest of the many 

 strange animals included in this order, is essentially an 

 Arctic form, frequenting the icy seas of the highest 

 latitudes, and rarely wandering to more temperate 

 regions. It frequents the coasts of Greenland, Spitz- 

 bergen, Nova Zembla, and Siberia, and was seen by 

 Parry as far north as lat. 81° 10', its favourite haunts 

 principally lying between 70° and 80°, South of this 

 zone it has very rarely been observed. Nilsson records
