GILBERT AND STARKS —FISHES OF PANAMA BAY 



93 



at their posterior euds by a distance equaling the diameter of the pupil; anteriorly 

 they converge, meeting at a point opposite the front of the eye. 



The gill-rakers are long and slender, the longest two-thirds to five-sevenths 

 the diameter of the eye, there being 5 or 6 movable ones on the vertical limb, and 

 11 or 12 on the horizontal limb, besides 2 or 3 immovable rudiments on each limb. 

 There are 51 or 52 tube-bearing scales in the course of the lateral line, corresponding 

 in number with the approximately vertical series along the back. Each vertical row 

 under the middle of the second dorsal fin contains 7i or 84 scales in the fifteen 

 specimens examined. The lateral line is pale, but is accompanied above and below 

 by short stitch-like lines of black pigment, one pair for each scale.
