 ray very much elongated. The whole surface minutely granulated, with the exception of 

 the fleshy portion of the tail and a very small space anterior to it, which are studded with

Monacanthus setifer, Dekay's Report, p. 337, pi. 59, fig. 194. 



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. Zool. Soc. of London, Pt. I., p. 112, 

 1830). 



GENUS III. ALUTERES, Cuv. 



An elongated body, covered with small and scarcely visible granules ; a sin- 

 gle spine in the first dorsal ; the chief character is in the pelvis, which is com- 

 pletely hidden under the skin, and is without that spinous projection observed 

 in the other Balistes.
