APPENDIX B. 



The Spotted Wrymouth (p. 63), has been recently discovered by the Rev. Mr. Linsley on 

 the shores of Long Island sound, near Stratford, Connecticut. 



APPENDIX C. 



Under the article Mossbonker, (p. 260), I should have stated more correctly that a wagon 

 load usually contains two thousand fish, and consequently that the number of these fish cap- 

 tured at Bridgehampton amounted to 168,000. I take this occasion to add, that this fish is 

 frequently known, on Long island, under the name of White-fish. 



APPENDIX D. 



Since the preceding sheets were printed, we have received the sixteenth volume of the 

 Histoire Naturelle des Poissons, de MM. Cuvier et Valenciennes. In this volume we 

 find a genus of Cyprinidae, hitherto undescribed, from this country. 



GENUS GOBIO. Cuvier. 



Dorsal and anal short, and without spines. Pharyngeal teeth conic, feebly bent at their 

 summits, and in two series. Barbels at the angles of the mouth.

[Communicated to Cuvier by Milbert, from the Falls of Niagara.] 



As the name of Labeo oblongus has been applied by MM. Cuvier and Valenciennes to a 

 species from Java, we propose to change our L. oblongus to elongatus.
