translucent; adult less variegated ; dull olivaceous, mottled with dusky. 

 Length 10 inches. Cape Cod to Cuba, abundant on our South Atlantic 

 coast and the Florida Keys; also found southward, through the West 

 Indies to Brazil, a large specimen from Bahia having been examined by us. 

 It occurs also in the Canaries and Madeira. This species has been identi- 

 fied by Giinther with the East Indian species, Monacanthus setifer, Bennett 

 (1830), but that species seems to have the dorsal spine weaker, rather less 

 than head. (Mspidus, bristly.)

2132. MONACANTHUS SPILONOTUS, Cope. 



Depth 2^. D. I, 32; A. 31; scales each supportiDg a pedicle, whose 

 summit divides into 4 or 5 radiating spines. Body elongate, outline of 

 front straight; dorsal spine long, with simple teeth, 4| in length of body; 

 dorsal and anal fins medially elevated; no brush or spines on caudal 

 peduncle. Pelvic shield elongate, spinous all around, the movable portion 

 present. Light brown; some longitudinal lines just below the dorsal fin, 

 the median developing a dark spot below middle of soft dorsal. Gulf of 

 Mexico. (Cope.) Not seen by us. Perhaps the young of M. Mspidus, but 

 more elongate than any specimens seen by us. (dTttkoS, spot; V(&TO$, back.)

2183. MONACANTHUS OPPOSITUS, Poey. 



Depth about ^ of total length. D. I, 27 ; A. 27 ; P. 12. Preanal flap not 

 extending beyond pelvic spine; profile of head not concave; dorsal spine 

 over posterior part of eye; spine smoothish in front, with 2 rows of barbs

 spines. Color yellowish brown, with dark points forming irregular, inter- 

 rupted longitudinal streaks on sides. Length about 6 inches. Cuba.

 the fins shorter, (oppositus, opposite, from the position of the dorsal and 

 anal.)
