behind and below the root of the pectoral ; it is very strong and long, 

 two-thirds of the length of the head, flattened, sharp outside, and 

 striated ; the first ray is the longest, scarcely longer than the spine 



The dorsal fin commences above the humeral ; it has ten strong 

 spines, longitudinally striated ; the third and foui'th arc longest, 

 their length being 3i in the height of the body. The membrane 

 between the spines extends to the upper third. The length of the 

 base of the soft portion is more than one-half of that of the spinous. 

 The rays are broken off. 



The origin of the anal fin falls below the end of the dorsal. The 

 first spine is scarcely shorter than the second, which is shortest ; the 

 two othei's are shorter, but nearly equal in length. 



Caudal rounded ? 



The scales are osseous, very adherent, not striated, each Math 

 three or four prominences behind ; those of the breast are largest ; 

 the fins are entirely scaleless. The lateral line commences behind 

 the scapulary spine, and is very curved on the trunk, like the back. 



The ground-colour now is yellowish, largely marbled with broAATiish. 

 The spinous portion of the dorsal and the vcutrals are brown ; the 

 other fins yelloMash.
