*I employ the name Eventognathi for the Cyprinoids as a sub-order instead of Pleetospondyli. The literal 

 meaning of the latter is woven together vertebrae, and the co-ossification of the anterior vertebrae is a character as 

 true of the siluroids as of the cyprinoids. Nematognathi and Pleetospondyli are by some regarded as orders, and 

 the latter is divisible into 3 sub-orders, viz: — Eventognathi., Heterognathi, and Gymnonoti, the first mentioned 

 alone of which is represented in our waters. I therefore employ the names Nematognathi and Eventognathi as 

 sub-orders of the order Ostariophysi.
