5. Giving due consideration to the fact that the 

 time of capture was unknown for all of the 

 samples and that the treatment of the sam- 

 ples had not been uniform, it is suspected 

 that this technique may have useful possi- 

 bilities in taxonomic studies of the adults. 



6. Chromatograms of the larvae, in repeated 

 runs of samples of the same species, showed 

 varying results. The inconsistencies in 

 these results may, in part, have resulted 

 from the loss of free amino acids from the 

 larvae due to leaching after death, prior to 

 their capture, or if taken alive, to the re- 

 peated freezing and thawing they were sub- 

 jected to while they were being segregated 

 from the rest of the plankton. Although the 

 amount and effect of decomposition of the 

 amino acids in the larval samples were not 

 investigated, this possibility cannot be ig- 

 nored. 



7. The author feels that any conclusion regard- 

 ing the use of chromatographic technique, 

 based on the present experiments, is pre- 

 mature. Nevertheless, he believes that 

 methods of applying this technique to taxo- 

 nomic" studies of adult and larval tunas can 

 be developed.
