Also an example from Thomasville (J. A. G. Rehn on March 

 25, 1904), Georgia. 



Erimyzon sucetta oblongas (Mitchill). 



Moxostoma claviformis Girard, Proc. Acad. Nat. Sci. Phila., 1856, p. 171. 

 Coal Creek, Canadian River, Indian Territory. 



No. 6,798, A. N. S. P., cotype of Moxostoma claviformis Girard. 

 Coal Creek, Canadian River, Indian Territory. H. B. Mollhausen. 

 From the Smith-sonian Institution (No. 165). 



Besides the very large series of examples from numerous localities 

 in the Middle Atlantic States, are others from: Richmond, Virginia; 

 Hicksville, Ohio; Marshfield, Missouri; Fort Smith, Arkansas. 



Minytrema melanops (Rafinesque). 



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

 p. 471. Yadkin River, North Carolina. 



Nos. 6,968 (type) to 6,970, A. N. S. P., cotypes of Ptychostomus 

 pidiensis Cope. Yadkin River, North Carolina. E. D. Cope. 

 These examples are undoubtedly the present species, as they show 

 the air-vessel in two compartments, and the bases of the scales 

 spotted. The adults Cope mentions in his description evidently 

 were not preserved, as they are not in his collections. 



Also one from the Ohio River, one from Indiana, one from Del 

 Rio in Texas, and one from Hartford in Arkansas. The last, a very 

 young example, I wrongly identified as Catostom,us nigricans}'^ 



Forbes and Richardson state^ that this species ranges on ''the 

 Atlantic Slope from New Jersey to North Carolina," though there 

 is no evidence whatever of its occurrence in New Jersey, so far as 

 I know of. Further, in view of the lack of detail, the single record 

 for its occurrence in the Susquehanna River basin may also be 

 questioned. 



Moxostoma anisurum (Rafinesque). 



Ptychostomus velatus Cope, Proc. Amer. Philos. Soc. Phila., XI, 1870, p. 470. 

 Youghiogheny River, Pennsylvania. 



Nos. 6,954 (type) and 6,955, A. N. S. P., paratypes of Ptychostomus 

 velatus Cope. Youghiogheny River, Pennsylvania. E. D. Cope. 



One from the Beaver River (Cope in 1880), Pennsylvania; one from 

 the Blue River and another from the Wabash River, Indiana. The 

 last example was identified by Cope with the following species, 

 but it has a slightly larger mouth and lips.
