Rafinesque's name. The Ptychostomus hucco Cope is certainly 

 identical with the present species. 



Moxostoma macrolepidotum (Le Sueur). 



Five from the Conestoga Creek in Lancaster County in Pennsyl- 

 vania, and two other examples without data likely were from 

 the same locality?. Also an example in the collection from the 

 Washington Market. 



I neglected to admit this species in my list of Delaware fishes, 

 though Cope had recorded it in 1870 without definite locality. 

 Along the Susquehanna River, in Maryland, it is known to some 

 of the fishermen, though is said to be less common than any of the 

 catostomoids. In Delaware, the fishermen know it along Broad 

 Creek at Laurel and Bethel. 



Moxostoma aureolum listed by Jordan^^ from Carlisle in Pennsylvania 



must be this species. 



Moxostoma lachrymale (Copej. 



Ptychostomus lachrymalis Cope, Proc. Amer. Philos. Soc. Phila., XI, 1870, 

 p. 474. Xeuse River, North Carolina. 



Head 4f; depth 3|; D. iv, 11, i; A, iii, 6, i; both V, i, 8; scales 

 43 in lateral line to caudal base, and 3? more on latter; 6 scales 

 above lateral line; 5 scales below lateral line; 16 predorsal scales; 

 snout 2| in head; eye 4|; mouth width 5|; interorbital 2|; length 

 12| inches. No. 6,848, A. N. S. P., type? of Ptychostomus lachry- 

 malis Cope. Neuse River, North Carolina. E. D. Cope. 



This example seems to differ from the preceding, as pointed out 

 by Cope, and may therefore be allowed as distinct. 

 Moxostoma duquesnei (Le Sueur). 



One example from the Youghiogheny River (Cope) and another 

 from a branch of the Big Mahoning Creek in Indiana County, 

 the latter recorded by me as Moxostoma aureolumP 



Following Cope's restriction, this species is allowed distinct 

 and identical with Le Sueur's fish, it being open to doubt that the 

 latter had Placopharynx. Moxostoma duquesnei is thus seen to have 

 more numerous scales in the lateral line than most of the species 

 of the genus. Other small-scaled nominal species, as Moxostoma 

 lesueurii (Richardson)-^ and Moxostoma alleghaniensis Nichols,^* 

 are either identical or very closely allied.
