Description. — The shape of the body is similar to that of Urano- 

 Scopus scaber. Its greatest height (.29), which is at the origin of the 

 spinous dorsal, is contained 4 times in its length in the young* and 3J 

 times in the adult. The greatest width of body (.24^) is nearly ^ of the 

 length, and equals the length of the ventral (.24i). The height at the 

 ventrals (.27) equals three times the distance from the snout to the cen- 

 tre of the eye (.09). The least height of the tail (.11) equals the width 

 of the interorbital area (.11), and is contained 9 times in the total length. 



The length of the head (.39) equals 3 times the length of the opercu- 

 lum (.13). There are two postocular depressions, whose length (.OTA) 

 equals their width (.07^), or slightly less than twice the length of the 

 snout (.04). The greatest width of the head (.31) equals nearly 3 times 

 the least height of the tail. The length of the upper jaw (.17) is con- 

 tained nearly times, and of the mandible (.23) 4J times in the total 

 length. The long diameter of the eye (.03^) equals | the length of the 

 longest anal ray (.14), and -fV of the length of the head. 



The distance of the spinous dorsal from the snout is about f of the 

 total length. The length of its base (.12) equals twice the length of its 

 first spine (.0(3). The spines are all shorter than in A. y-grcccum. The 

 second spine equals the first, and 3 times the last (.02). The length of 

 the base of the second dorsal (.30) equals times the length of its last 

 ray (.05). The first ray equals the first spine in length. The longest 

 ray (.IG^) is contained G times in the total length. 



The distance of the anal from the snout (.GO) equals twice the length 

 of the second dorsal base (.30), and nearly twice the length of the anal 

 base (.31). The first anal ray (.04) equals the snout in length. The 

 longest (.14) slightly exceeds in length the operculum, while the last 

 (.07j^-) about equals the length of the postocular depression. 



The length of the middle caudal rays (.23-?r) is usually a little less than 

 that of the ventral (.241). 



The distance of the pectoral from the snout (.36) equals 3 times the 

 length of the base of the spinous dorsal. The length of the pectoral 

 (.29) exceeds the length of the ventral (.24^) by about \ of the length of 

 the latter, and is contained nearly 3^ times in the total length. It ex- 

 tends to the 5th anal ray.
