No. 1. — List of the Fishes sent by the Jfriseum to different In~ 

 stitutions, in exchange fur other Specimens, with Annotations. 

 By F. W. Putnam. 



[Authentic labels accompany the specimens, having numbers on the left corre- 

 sponding to those attached to the specimens. The figures on the right margin 

 designate the number of specimens forwarded of each species.] 



From the Fresh Waters of Forth America. 



Lcpidosteus osseus LaCepede, Hist. Nat. Poiss. V. p. 333. 1803. 



Lepidosteus oxyurus Rafixesqce, Ichth. Ohien. p. 73. 1820. 



Cylindrostcus platostomus Rafinesqce, Ichth. Ohien. p. 72. 1820. 



The synonymy of the species of the genera Lepidosteus and Cylindros- 

 teus is very complicated. The specimens included under the name of 

 Lepidosteus osseus LaCepede are from South Carolina, the locality of 

 Linnscus's Esox osseus, which LaCepede has confounded with the Lepi- 

 dostt its ferox of authors, from the Mississippi lliver, under the name of 

 Lepidosteus spatula. 



Polyodon folium LaCepede, Hist. Nat. Poiss. I. p. 403. 1798.

Pimelodus atrarius DeKay, Fishes N. York. p. 185. 1S42. 



The specimens of Pimelodus forwarded are undoubtedly identical with 

 the species described by DeKay under this name, but it remains to be 

 proved that DeKay's species is not synonymous with some one of Ra- 

 finesque's. 



Pctromyzon americanus LeSueuh, Trans. Am. Phil. Soc. (New Series.) 

 I. p. 3S2. 1818. 



Ichthyomyzon argenteus GmAnn, Pac. P. P. Surv. X. p. 381. 1S59.

Anguilla bostoniensis LeSuedr, Jour. Philad. Acad. Nat. Sci. I. p. S2. 

 1817. 



We question the validity of the several species of Anguilla that are 

 described from our sea-coast and fresh waters. 



Uranidea gracilis Putnam, MS. 1856. 



Svx. Cottus gracilis Heckel, Ann. Wien. Mus. II. p. 148, 1837; Ura- 



quiescens DeKay, 1842. 

 We do not see the necessity of the name AcantJtocotlus, proposed by 

 Girard for the marine species of the old genus Cottus, when DeKay, 

 many years before, by giving the name of Uranidea to one of our fresh-
