 cealnient in water. In alcohol they fade to light brown or slate color; 

 (he lower surfaces paler. There are no spots or darker markings of any

As may be seen from the accompanying list of specimens, the range 

 of this species is quite limited. It has not been found outof the rivers 

 of ISTorth and South Carolina.
