Generic Characters. — Body smooth, without scales ; dorsal and anal fins 

 opposite, and near the tail ; pectoral fins large, descending to tlie inferior surface 

 of the body, and by an extension of the membrane surrounding an oval disk ; 

 ventral fins united by a membrane winch extends circularly under the belly, 

 forming a second concave disk. 



Baron Cuvier lias called the tliird family of tlie Sub- 

 bracliial JSIalacopterygii, Discoboles, on account of tlie disk 

 formed by the union of the ventral fins. The term Cyclop- 

 TERiD.E, derived from an original Linnsean generic name, is 

 here adopted in order to preserve uniformity in the names of 



* The family of the Sucking-fishes.
