IIaijitat. — Mississippi Valley, in all the larger streams. 



This species is found in some abundance in the larger streams. At 

 the Falls of the Ohio, it is taken in nets, and meets a ready sale. It is, 

 however, much less abundant than the Buffalo fishes are. From the 

 general use of the name '' Missouri Sucker", its abundance in the State 

 of Missouri* may be inferred; but, as to the facts in the case, I am not 

 informed. This fish is as sharply distinguished from the other Suckers in 

 its appearance as in its anatomy. The dusky colors and the smnll size 

 of the head attract attention at once. 



But one species is yet known. That being the case, the synonymy of 

 the species needs no discussion, its oldest name being the one in com- 

 mon use.
