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.
