 juveniles represented by crosses, transforming prejuveniles by open circles, and transformed juveniles and adults by

No series contained both nietainorpliosing and 

 metamorphosed specimens. 



The largest specimen with the transitional 

 coloration was trawled from 3 fathoms off Soldier 

 Key, Florida (table 1). According to the label, 

 it was estimated to be 2 inches (about 50 mm.) 

 total length at capture (about 40 mm. standard 

 length). The transitional (or transformed) colora- 

 tion would be expected under those conditions 

 unless the fish had just settled to the bottom

when captured. It wjis then kept in an aquarium 

 at Marineland, Florida, for about 2K months, 

 and during this time it grew to a total length 

 of 93 mm. (73 mm. standard length). At 73 mm. 

 the fins still retained the transitional coloration, 

 the body remained dark, and the eye was still 

 relatively small. How long the specimen would 

 have retained these transitional features is un- 

 known, but they were retained, under these 

 unnatural conditions, on this much larger speci-
