as Sand Sucker or Striped Sucker. My specimens are iden- 

 tical with those from the Ohio River and the Great Lakes. 

 If E. sucetta (Lacepede) is not the same as E. melanqps, we 

 can never know it until specimens are taken in the original 

 localities. The name sucetta has priority.

35. MYXOSTOMA EURYOPS. Sp. nov. 



I dislike to introduce another specific name into a genus 

 already overloaded with nominal species, but the present 

 fish is so singular in its physiognomy, and so apparently un- 

 like the other species of this genus, that I do not know what 

 to do with it unless I give it independent rank. The only 

 species which seems to be at all similar is M. bucco (Ptychos- 

 tomus bucco Cope, Hayden's Geol. Surv. Wyoming, 1870, 

 437). 



Body stout, compressed, heavy forwards, tapering behind into a slender 

 caudal peduncle ; depth 4 in length ; head 4£ in length, very short, deep, 

 and thick, almost cubical, the snout prominent and nearly vertical, the 

 profile being abruptly decurved in a manner very unusual among Suckers ; 

 eye excessively large, longer than snout, near to the top of the head, 

 forming more than one-third of the side of the head (in a specimen six 

 inches long), nearly equal to the wide and flattish iuterorbital space. 

 Vertex slightly concave ; mucous ridges rather prominent. 



Greatest width of head (through cheeks) greater than the width of the 

 body, and equal to greatest depth of head, 1£ in length of head, and 6 in 

 length of body ; mouth inferior, the lips but faintly plicate ; lower lip full, 

 truncate behind, not ^-shaped. 



Scales large, equal ; 15 before dorsal fin ; lateral line distinct and nearly 

 straight, with 43 scales.
