ERIMYZON SUCETTA. 



147 



Professor Agassiz's anisurtts, considered by him as the Western rep- 

 resentative of oblongus, must belong Lere. Professor Agassiz's tennis 

 from Mobile is not described ; but as sucetta occurs abundantly in Ala- 

 bama, it is safe to presume their identity. The type of Moxostoma cla- 

 riformis Girard is now lost. Both figure and description point to the 

 young of sucetta. The figure represents the scales rather smaller than 

 usual, but it may not be correct. The types of Moxostoma Jtennerlyi 

 Gftard and of Moxostoma campbelli Girard, from Texas, have also disap- 

 peared ; but they too seem to have been based on the young of the 

 present species, and as sucetta certainly occurs in Texas, these nominal 

 species must fall into the synonymy. 



The Chub Sucker is one of the smallest species, rarely reaching a 

 length of more. than a foot. It is tenacious cf life, and bites readily at 

 a small hook, but is not much valued for food. The young are rather 

 handsome, the black lateral band being sometimes very distinct. In 

 the aquarium, they act as scavengers. The adult fishes, especially the 

 males, are very dusky in color, and the males in spring are provided 

 with three large tubercles arranged in a triangle on each side of the head. 

 The fins of the adults are usually black, sometimes tinged with red.
