Tliey iHimhcT 11 or IT) on the lower liinl) of the areli, ami in Iciii^tli are from three- 

 fifths to two-thircia the diameter of the eye. 



The character of width or position of the cross-bars is without value. In one 

 nf our small specimens, the second l)ar on one side occurs directly midway between 

 the first and second bars on the reverse side, wliile the third bar is only a little behind 

 the second bar of the reversed side. The first two bars are not always nearer 

 together than the others, as described by Jordan and Evermann. The bars are not 

 so conspicuous in our small specimens as in the larj^e ones, but they are evident. 



In our specimens of T. glaucits, the dorsal formula is V, I, 19, the anal 

 III, 17. Tlie gill-raUers arc short and thick at the base and taper rapidly to a 

 point. They number !J on the lower part of the arch, and in length are Imt 

 one-third the diameter of the eye.
