CRUSTALOGY, noun [Latin , a shell, Gr., discourse.] That part of zoology which treats of crustaceous animals, arranging them in orders, tribes and families, and describing their forms and habits. [Crustaceology, the word sometimes used, is ill-formed, and its derivatives inconveniently long. Who can endure such words as crustaceological?]
