					                         Classifying Dragons

       Imagine that you are a famous space explorer and biologist. You have
recently arrived on the planet Nitram. Your job is to study the Nitramian
animals and develop a system for classifying them.
       You decide to begin your work by classifying Nitram’s dragons. You
think that this name is not very scientific. However, you must admit that
the animals look a lot like the monsters of Earth legends.
       You ask the computer to give you a brief summary of all the
information it has on Nitramian dragons. The computer produces the
following printout.
