Dr. Liitken’s views (Spolia Atlantica, 139) as to the transformations 
incident to its growth. We see no difference between Atlantic and 
Pacific coast specimens.

This species represents C. chrysurus on the Pacific coast of tropical 
America. It is very similar to the latter, and will probably be consid- 
ered as a geographical variety of it when these fishes are better known. 
RECAPITULATION. 
We have in this paper admitted 30 species of Carangine. More or 
less doubt is attached to the nomenclature or systematic position of 
several of these. We therefore repeat the list here, with the nature of 
the doubts remaining to be solved in each case. The general distribu- 
tion of the species is indicated by the letters W. (Western Atlantic), 
A. (Western Africa), P. (Eastern Pacific, Panama, &c.), E. (East In- 
dies).
