 near vent; dorsal region spinous from a little behind the nares

Brownish above, faintlj' verraiculated with lighter; sides yel- 

 lowish, becoming white below; fins uniform light yellow; a 

 brown spot at base of pectoral. (x\fter Cope) 



The hairy blowfish is known only from the small specimen 

 4 inches long described by Professor Cope; the specimen was 

 taken in the Gulf Stream off Newport. Jordan and Evermann 

 suggest that it may be the young of Spheroides p a c h y -

 be nearer to S. n e j) h e 1 u s (Goode & Bean), Proc. U. S. Nat. 

 Mus., 412, 1882, a southern species known from Georgia to 

 Texas. 



No specimens have been recorded from waters of New York.
