ICHTHYOLOGICAL REPORT 



SINCE- the report on the Fishes has passed through the press, 

 I have had an opportunity, by the politeness of Mr. John S. 

 Sleeper, Editor of the " Mercantile Journal," of examining a 

 specimen of the " Lophius piscatorius" Sea-Devil ; and as the 

 account embodied in my report was extracted from Yarrell's 

 " British Fishes," I would present a description here from a 

 recent specimen, that the ichthyologist may judge for himself, 

 as to my correctness in considering our fish the same as the 

 foreign species. 



Length of the specimen before me, two feet and one inch ; 

 width across, in front, of the pectorals, one foot ; length of the 

 head, from the tip of the snout to the occiput, six inches. All 

 the upper part of the body, is of a dark brown color, caused by 

 very minute irregular markings ; body beneath, white. Nu- 

 merous fleshy cirrhi beneath the lower jaw, edging it to the 

 angles ; beyond these, they are continued to the pectoral fins, 

 and back of them, they are again continued to the tail ; these 

 cirrhi are, beneath the jaw, nearly an inch in length, on the 

 sides of the body they are much smaller. The vertical gape of 

 the mouth, when expanded, is five inches ; the distance across 

 from angle to angle of the upper jaw, eight inches ; the tip of the 

 lower jaw projects nearly two inches, in front of the upper.
