The Wilkes example varies chiefly in its nearly uniform 
brown body, without the pale band found on so many specimens; 
very faint traces of pale blotches on lower side of the head; 
very pronounced white blotch before blackish one at beses of 
the last dorsal rays. This latter ne the chief character 
for P. ellipticus Jordan and aie which thus appears 
synonymous. Our series of specimens show not only variation 
in this respect, but elso the disappearance of the broad pale 
vertical band or even partial obliteration of the black axil- 
lary and blotches at last dorsal rays basally.
