Habitat.—Pacifie coast of tropical America; Panama. 
This singular fish is not uncommon about Panama, where several 
specimens were obtained by Professor Gilbert. Of all the known spe- 
cies of Scienide this one kas the mouth most nearly vertical. There is, 
however, ip its structure nothing to warrant its separation as a distinct 
genus, Amblyscion. Many specimens from Panama are in the museum 
at Cambridge.
