1716 Btdletin ^7, United States National Miisenvi. 



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

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

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

 ludies 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 Gunther with the East Indian species, Monacanthus setifer, Bennett 

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

 than i head. (Mspidtis, bristly.)
