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

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

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

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

 forming a second concave disk. 



BARON CUVIER has called the third family of the Sub- 

 brachial Malacopterygii, Discoboles, on account of the disk 

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

 TERID^, 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.
