The Cypridida; aud Catostomidcc iucluded in these collectious were 

 nearly all described for the first time in a paper entitled " Eesearches 

 upon the Cyprinoid fishes inhabiting the fresh waters of the United 

 States west of the Mississippi Valley, from specimens in the museum 

 of the Smithsonian Institution." This was i)ublished in the Proceed- 

 ings of ,the Academy of Natural Sciences of Philadelphia, 1850, pages 

 154-208. 



Girard's descriptions of these difficult fishes are very far from good. 

 The characters noted are usuallj' superficial ones, and real si>eciSc dis- 

 tinctions, such as differences in the numbers of the scales of the lateral 

 line, are generally overlooked.. 



After Dr. Girard's connection with the Smithsonian Institution had 

 Closed many of his labels became obliterated ; some of his types were 

 lost or destroyed, and a certain identification of many of his species 

 could not be made. A careful examination of the material studied by 

 him, including many bottles from wliich tlie labels have been lost, has 

 enabled the writer to positively identify very many of his types not 

 hitherto recognized. , There is also a series of manj' of Girard's types in 

 the i)ossession of the Academy of Pliiladtlpbia, these having been pre-'^ 

 sentt'd many years ago by the Smithsonian Institntion. These types 

 have been studied by Mr. Seth E. Meek, and many of them by the 

 writer also. iv 



The present ])aper contains a lis^ of Girard's si>ecies, arranged In the 

 order given by him, and opposite each my identification of it. Those 

 species of which the types are still in the National Museum are indicated 

 by a star (*); those which are found at i)resent only in the Academy of 

 Sciences by a dagger (t). A number of synonymic notes aie added. A 

 few notes taken from manuscripts of Mr. Meek, and not verified by me, 

 are credited to him.

' This is the ordinary northern Erimi/zon, described in Jordan &l Gilbert's Synopsis, 

 p. l'^'.^, as Erimijzon micetla. The two forms of Erimyzon seem to grade into each 

 other. South Carolina examples belong to the southern type, which is, therefore, in 

 all ])robability, the real Cijijrinus suceita of Laccpiide. The northern form (siicelta of 

 the Synopsis) may stand as Erimi/zon sucetta oblongus, and the southern form (E. goodei of 

 the Synoj'sis) as Erimi/zon sucetia. The southern form ranges from South Carolina to 

 Texas, and the type of J/, kenncrlii belongs to it. i
