Esox Rafinesque becomes again Belone Cuvier. 

 Glossamia pandionis becomes Xystramia pandionis. 



There are no species of Leucos in America, the 

 species so-called being referable to Myloleucus Cope 

 and Hesperoleucus Snyder. There are, according 

 to Prof. Cockerell, no true species of Leuciscus in 

 America or Japan. The American species, so- 

 called, stand for the present as Richardsonius Gerard, 

 though some of the included sections (Clinostomus, 

 Phoxinus, Hemitrcmia, Siboma), may prove to be 

 of generic value. Cheilonemus Baird replaces Leu- 

 cosomus, preoccupied. Cremnobates Giinther re- 

 places Auclienopterus, preoccupied. Cynicoglossus 

 Bonaparte replaces Microstomas, preoccupied. Eu- 

 dulus Fowler replaces Dides. Evermannellus Fow- 

 ler replaces Odontostomus. Haloporphyrus Giinther 

 replaces Lepidion. Notoscopelus Giinther replaces 

 Macrostoma. Quassilabia Jordan and Brayton re- 

 places I j ago chillis. Scaphirhyncliops Gill replaces 

 Scaphirhynchus. Stcncsthes Jordan replaces Steno- 

 tomus, preoccupied. The Scup becomes thus Sten- 

 esthes chrysops. Xiphister Jordan and Gilbert re- 

 places Xiphidion. 



. CarcharJihnis coinmcrsoni Blainville should 

 probably stand, instead of C. lamia. I sums tigris 



(Atwood) replaces I sums dckayi, Isurus oxyrhyn- 

 chus European species not yet known from our 

 coast. Lamna nasus ( Bonnaterre ) , has priority over 

 Lamna cornubica (Gmelin). Mustelus Valmont, 

 1764, or of Linck (1790), must stand for the smooth 

 "Dog Sharks," which may for the present, pending 

 investigation be left in one genus. Mustelus Valmont 

 is equivalent to Cynias Gill, Mustelus Linck to 

 Pleuracromylon. The species are Mustelus asterias 



(Valmont) or Cynias canis (Mitchill) and Mustelus 

 or Pleuracromylon mustelus (L.) 



The name Raja diaphanes Mitchill replaces 

 Raja ocellata (preoccupied) Raja scabrata Garman 

 replaces Raja radiata (not found in America) and
