With the Dolphins, we close the series of fishes having Scombroid 
affinities, and begin the equally important serics of PIERCI- 
FORMES, those related in some degree to the common Perch. 
The Perch-like fishes have usually larger and rougher scales than 
the Scombroids, and the development of the spinous armature of 
the fins is in general more pronounced. We begin with one of the 
most aberrant forms, the small
