I supposed, previous to the appearance of Dr. Dekay’s Report, this species to be Mitch- 
ill’s M. broccus, and thus I called it in the ‘* Proceedings of the Boston Society of Natural 
History,” p. 84 (Sept. 1842), Dr. Dekay’s specific name has been previously applied to 
another species of the genus by Bennett (Proceed. Zo]. Soc. of London, Pt.1., p. 112, 
1830). 
GENUS III. ALUTERES, Cuv. 
An elongated body, covered with small and scarcely visible granules ; a sin-

pletely hidden under the skin, and is without that spinous projection observed 
in the other Balistes.
