The order Perciformes, to which we now come, is a very large one indeed and our survey of it will continue as far as page 144. The common feature of fish in this order is some degree of structural resemblance to the perch, manifest in the position and spininess of fins and other such details. We begin by examining one of the most important families in the order, that which includes the sea basses and the groupers.
