The Spadefish (Chaeto- 

 dipterus faber) is a tropical 

 species reaching the latitude 

 of New York in summer. 

 It is esteemed as a food fish, 

 attaining a weight of fifteen 

 pounds. It feeds to some 

 extent on the jellyfish called 

 the Portuguese Man-of-War 

 (Physalia). It is a hardy 

 fish, living many years in 

 captivity. It can change in- 

 stantly from white to black, 

 or to the banded phase 

 shown here. 



The Sheepshead (Archo- 

 sargus probatocephahis) is 

 found along the Atlantic 

 and Gulf coasts, but is not 

 abundant in the latitude of 

 New York. It is an excel- 

 lent food fish and more than 

 two million pounds are ta- 

 ken annually. Large speci- 

 mens weigh from fifteen to 

 twenty pounds. It takes the 

 hook readily and affords 

 much sport to the salt wa- 

 ter angler. It has been kept 

 at the Aquarium for five 

 vears at a time. 



The Quillback (Carpi- 

 odes velifer) of the Missis- 

 sippi Valley is often to be 

 seen in our collections. It 

 dues not exceed a foot in 

 length and has little com- 

 mercial value. The pro- 

 longed first dorsal ray gives 

 it its name. It belongs to 

 the group of fishes called 

 carp-suckers, and abounds 

 in sluggish waters, where it 

 does much rooting in the 

 mud. Specimens have lived 

 in the Aquarium three years.
