Specimens from the Catawba River all have a relatively longer head 
than typical examples from the Potomac; former 4 times in length to 
basis caudal fin ; latter 4.5 times. They have also teeth 4.1—1.4, in place 
of 4.22.4; the three inferior of the outer row obtuse, without hook, the 
superior one only with masticatory face. Both varieties may really be- 
long to the H. hudsonius, as indicated in Monograph Cyprinide Penn- 
sylvania.
