DescrijJiion of the specimen. — Although the specimen is somewhat 

 deformed by stirffing, and has the pectoral and caudal fins mutilated, 

 I do not hesitate to found a new species on it, its characters being 

 so very distinct. The greatest height of the body is 1| in the 

 length, Avithout caudal. The snout appeal's to be rather produced 

 and slightly pointed. The dorsal has only a thin coat of scales, and 

 its anterior part is nearly free ; the spines are very strong, and 

 increase to the fourth, which is 1 5 in the length of the head ; the 

 follo\\'ing gradually become shorter to the eighth, the ninth to the 

 thirteenth being nearly equal. The soft portion of the fin is not 

 elevated and rounded posteriorlj'. The second anal spine is the 

 longest and equals the foiu'th of the dorsal. The soft portion is 

 rather higher than the soft dorsal.
