ERIMYZON SUCETTA. 147 Professor Agassiz's anisurus, considered by him as the "Western rep- ri'seutative of ohlongus, must beloug here. Professor Agassiz's tenuis from Mobile is uot described ; but as sucetta occurs abundantly in Ala- bama, it is safe to presume their identity. The type of Moxostoma da- tiformis Girard is now lost. Both figure and description point to the yoang of sucetta. The figure represents the scales rather smaller than usual, but it may not be correct. The types of Moxostoma Irnncrli/i Girard and of Moxostoma campbelli Girard, from Texas, have also disap- peared ; but they too seem to have been based on the young qf 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 lleugth of more than a foot. It is tenacious cf lile, and bites readily at asmall hook, but is not much valued for food. The young are rather lliandsome, the black lateral band being sometime very distinct. In ! aquarium, they act as scavengers. The adult lishes, especially the Imales, are very dusky in color, and the males in spring are provided litilh three largo tubercles arranged in a triangle on each side of the head. IThe fins of the adults are usually black, sometimes tinged with red. Spedmms in United'States National Museum. Xumber. Locality. Collector. 144 Sugar Loaf Creek, Nova Scotia ...... ...... H. B.
