and more or less rectangular figures, between which are 

 similarly shaped prolongations downward of the black 

 ground.* Many show the red blotches spread out and 

 blended above, so that the downward prolongations of the 

 ground color have become detached and form a series of 

 black spots separated by red, from the narrow band of 

 ground color remaining on each side of the light dorsal 

 line. In others these black spots have become united and 

 form a black line, so that on each side of the light dorsal 

 line we have a line of black, one of red, another of black, 

 and the light lateral line.f In one specimen the black is 

 almost entirely replaced by red. These color variations are 

 all individual, none geographical.
