Excerpt from The Lampreys and Fishes of Indiana Of these classes we have in Indiana representatives of two only, our waters supporting neither lancelets nor any form of shark-like animals. The classes represented are named and distinguished as follows: A. Body long and slender, eel-like; skin smooth and slippery, wholly devoid of scales; no paired fins; no lower jaw; the mouth placed in or near the center of a large, circular and sucker-like disc; no bony skeleton. Cyclostomi, p. 148. Aa. Body short or long; usually, but not always, furnished with scales or bony plates; paired fins rarely entirely wanting; lower jaw always developed; a bony skeleton always more or less devel oped, thus comprising a considerable number of membrane bones. Pisces, p. 152. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
